Introduction
As modern surveying equipment and methods have evolved, LSS has also developed
much more functionality in order to make the most of the techniques available. This is
especially true when it comes to data acquisition, field coding and transfer from survey
instruments. McCarthy Taylor Systems Ltd has strived to ensure that LSS surveyors are
able to make the most of the options available.
This workshop manual has been prepared for trainees attending the LSS and Survey
Instruments workshops to help with the configuration of both the survey instrument and
computer laptop. It is normal (and recommended) that the trainees bring their own
instruments and laptops to the workshop, so that they leave with a fully configured and
working system.
Hence we will start by ensuring that the latest version of LSS is installed on the trainees’
laptops, upload a standard LSS code list onto the instrument and make any required
configuration changes to the survey instrument.
We will look at feature coding for strings and points, plus the LSS ‘Reserved codes’ and
how these can be used to add extra observations effectively and efficiently into the LSS
survey.
There will be a practical exercise outside to help demonstrate these options, followed by
the downloading (transferring) of the practical exercise survey data onto the laptops and
the processing in LSS.
We will finally look at the export commands in LSS to see how we can upload design
data for setting out back onto the instrument. We will also look at how to update the
LSS legend in a typical LSS prototype survey before creating the necessary code lists to
upload back onto the survey instrument.
The workshop is split into four teaching sessions as follows.

Session 1
Duration:
1.1
Installing LSS, Tutorials and Testdata
1 hour 30 minutes
If the latest version of LSS is not set up on the laptop then the program can be installed
either from a DVD or following downloading from the LSS website at dtmsoftware.com.
From the DVD, the following Installation allows the user to install LSS and Tutorials,
Files for Surveyors for different survey instruments, Rough Guides, Utility Programs, 3D
Demos and the 3D Vantage program.
Follow the default install unless LSS is already installed on this PC.
Testdata contains example data/settings and includes the legend prototype for those
new to LSS (see Configure).
We can install Tutorials and Testdata separately.
The Deskey dongle drivers installation will automatically follow the LSS install but is not
needed if LSS is already running on the PC.
Page 4 of 58
1.2
Installing Other Files used by LSS
Survey Instrument Support Files
The Survey Instrument support files are also found on the LSS installation DVD, under
‘Files for Surveyors’:
Leica System 1200 includes Viva and the new Nova instruments and for all these loggers
on this platform it is recommended that the survey data is transferred to pc using the
Leica 1200 (DBX) Database Reader, which is installed by hitting the icon below:
Page 5 of 58
This will create a new folder ‘Leica 1200 DBX’ immediately beneath the default folder
which will be the LSS root program folder, namely C:\MTPSYS.
The System 1200 DBX database reader can also be installed from the LSS Installation
DVD using Windows Explorer to find (and run) the Leica_1200_dbx.exe file in the Leica
\ 1200 \ Leica_1200_dbx directory.
All the required installs have been grouped together at the bottom of the above screen.
Page 6 of 58
Next the System 1200 Example Codelist is installed on the C:drive from the Codelist
directory on the DVD. Three codelists area available on the DVD: the standard LSS
Prototype, the road markings prototype and an advanced version, which uses some
higher functions on the Viva. These are pre-formatted for immediate upload to the
System 1200 instrument without the need to go via Leica Geo Office Tools and we will
transfer across to the instrument data card or USB stick.
Or the codelist files can be copied direct from the DVD onto the Leica System 1200
memory card.
The Leica System 1200 GPS Format File can be ignored here – the GPS or TPS
format is copied over as part of the DBX database reader.
But we will need to install Leica Geo Office Tools Program by saving the zip file,
unzipping on the C: drive and running the ‘Setup.exe’ file to install Leica Geo Office
Tools on the pc.
Alternatively we can open the DVD with Windows Explorer, find the
Leica_Geo_Office_Tools_en directory in Support files \ Leica, and run the Setup.exe file.
For Leica TPS instruments, Leica Geo-Office Tools is the communication software from
Leica and we will see later in the workshop how we use this software to add new feature
codes into a codelist and transfer the updated codelist to the Leica 1200 platform
instruments.
All these files are also available for downloading and installing from the LSS website at
dtmsoftware.com.

Rough Guides
The following window is invoked when selecting the ‘Rough Guides’ from the Home
screen:
For example clicking on 1 Feature coding for Land & Eng. Surveyors will open a
very useful document ‘Principles of Survey and Feature Coding’ as a pdf file.
This describes in detail the aspects of coding and stringing on the logger for optimum
input into LSS and we will look at some of the details later on as part of the practical
exercise.
The other useful pdf document that can be downloaded and printed is the LSS instrument interface guide on setting up LSS and Leica System 1200 / Viva on which
this manual has been based.

1.3
Installing Programmer’s Notepad File Editor
The LSS installation DVD contains a shareware program called Programmer’s Notepad
File Editor that we have found ideal for editing large files of data. It is found in ‘Utility
Programs’, or the program can also be downloaded from the LSS Website.
Page 9 of 58
This will install Programmer’s Notepad on your
computer. Follow the installation defaults
including the destination location;
C:\Program Files(x86)\Programmer’s Notepad.
Later on we will set this to be the default File
editor in LSS Configure Hardware and
System – File Editor.
Page 10 of 58
1.4
Configuring Leica System 1200
The two requirements for using LSS coding to the best advantage are a relevant code
list and a subset of the config set both of which have identical usage for both TPS and
GPS.
Note: the instrument firmware is important for the support of some of the functions in
this section. If you do not have the latest firmware, particularly if it is earlier than
Version 5.62, not all the options will be available.
Code List
An example code list has been built from the LSS prototype legend (supplied with
Testdata) on the LSS DVD (in ‘Support_files\Leica\1200\code_list’) and already
copied to the C: drive folder earlier.
The LSS point features translate as ‘point codes’ and the LSS link features as ‘point
codes with lines’ (replacing the use of ‘line codes’ for processing purposes).
The following steps explain the method of transferring this code list to the System 1200;
1) Copy the required Code list files .XCF, .X06 and .X23, from the LSS DVD ‘Code
lists’ folder to the ‘Code’ folder on the card.
* Note : The 1200 Simulator card folders are in ‘Configuration/Data Paths/PC card
path’
2) Transfer the Compact Flash card from your computer to the System 1200 sensor.
* Note : The Compact Flash card must always be “Stopped” before removing it
from the PC and the System 1200 must always be switched off before removing
the Compact Flash.
3) Select option 6 Tools… from the Main Menu.
* Note : This option can be selected by
pressing the number 6 key, or by navigating
to 6 Tools... and pressing the Enter key, or
by touching the Tools… icon when using an
active touch screen.
4) Select option 2 Transfer Objects… from the
Tools Menu.
5) Select Codelists from the Transfer Objects
Menu.
6) In the ‘Transfer Codelists’ screen copy ‘From
CF Card’ and ’To System RAM’, select the
copied code list and CONT [F1].
Page 11 of 58
Config Set Alterations
This contains all the predetermined settings for a Leica 1200 instrument of which the
Display mask and the Coding/Linework elements are important to LSS;
Display Settings (Display masks)
The LSS example display mask tab shows the Code
and its description along with up to five associated
attributes (as used by the example prototype tree
feature PD).
Use the scroll bar to reach the fifth attribute e.g. the
tree species in the LSS example code list.
To amend your display mask to match that shown above choose Management /
Configuration Sets from the main menu. Highlight the configuration set to be updated
then select New to create a copy of this config set (select [F3] Edit to change the
existing one) typing in the new Name and Description etc. Click Store to create the
copy.
On the Wizard Mode screen select [F6] List / Display Settings and [F3] Edit.
We suggest the following settings;
Mask 1 Survey - leave as your preferred view of the measurements etc
Mask 2 Offset - remove this by setting ‘Use in Survey’ to NO (not needed for
LSS).
Mask 3 Code – change to see the code list attributes as below by clicking DMASK
Enter the Lines as shown below using the scroll bar to access the settings as shown in
the second screen capture.
Then select [F1]
‘CONT’ twice to
accept these
changes. Coding
& Linework
Settings
Note: These changes are necessary in order for the LSS coding to perform correctly.
On the Wizard Mode screen again select ‘Coding and Linework Settings’ /[F3] ‘Edit’.
Page 12 of 58
This is essential for the correct use of the Code list
etc.
1. ‘Quick Code’ set ‘Off’ although the prototype code
list has been set to use 3 digit codes if this is
switched ‘On’.
2. The ‘Rec Free Code’ set to ‘Before Point’.
3. ‘Attributes’ set to ‘Last Used’ means that values
added for a feature code will be remembered
when it is used again.
4. ‘Mand Attribs’ set to ‘Code change Only’ so that
shots without a change of code will not request
the attribute values again e.g. a row of trees all
with the same dimensions.
5. ‘Thematc Codes’ set to ‘With Codelist’ allows the
Code input to enter the codelist.
6. ‘Show codes’ set to ‘All Codes’.
7. ‘String Attrib’ set to ‘1’ will use the string number
attribute as set in the LSS prototype codelist.
8. Then select the ‘Linework’ tab. Check that ‘Begin
Line’ is set to ‘BEG’ to allow LSS to automatically
recognise a System 1200 start of string.
9. Finally press CONT to confirm settings and
[F1] ‘Store’ to update the configuration set.
ID Templates
On the Wizard Mode screen again select ‘ID
Templates’ / [F3] ‘Edit’.
Note: The settings should be made according to
those shown so that the instrument can increment
the numbering systems efficiently.
If these settings are not available, then the firmware
may need to be re-installed. Please contact Leica for
advice.
Hot Keys and User Menu
On Wizard Mode again select ‘Hot Keys and User
Menu’. Set ‘Hot Keys [F7]’ to be
‘Select Free Code’.

1.5
Configuring Leica Viva System
The two requirements for using LSS coding to the best advantage are a relevant code
list and a subset of the config set both of which have identical usage for TPS and GPS.
Code List – An example code list has been built from the LSS prototype legend
(supplied with Testdata) on the LSS DVD (in ‘Support_files\Leica\1200\code_list’)
and already copied to the C: drive folder earlier.
The LSS point features translate as ‘point codes’ and the LSS link features as ‘point
codes with lines’ (replacing the use of ‘line codes’ for processing purposes).
The following steps explain the method of transferring this code list to the Viva logger;
1) Copy the required Code list files .XCF, .X06 and .X23, from the LSS CD ‘Code lists’
folder to the ‘Code’ folder on the card or USB memory stick.
2) Transfer the Compact Flash card / USB memory stick from your computer to the
Viva logger.
3) Select User from the Main Menu.
4) Select option 4 Tools & other utilities.
5) Select 1 Transfer user objects.
6) In the ‘Transfer User Objects’ screen select
“Codelist” as the Object to transfer from
‘From’ CF Card or USB
‘To’‘ Internal memory, select the relevant code list
and OK [F1].
Page 14 of 58
Work Settings
1. Now from the ‘User’ menu select ‘1 ID
Templates’
2. Set the TPS points to be manually entered
with an increment of ‘1’.
It may be necessary to go down one to Area001 first,
to effect this change.
3. Go back to the ‘User’ menu and select
Page 15 of 58
Coding & Linework
4. Under ‘Code & attributes’ tick the box to
‘Use a list box to view codes’ , then set
the ‘Suggested attributes’ to ‘Last Used’.
This means that values added for a feature /
string number will be the next default input.
5. ‘Prompt for Mandatory Attributes’ should
be set to ‘Code change Only’ so that making
a shot without changing the code will not
request the attribute values again e.g. a row
of trees all with the same dimension.
6. Under ‘Linework’ tick the option to
‘Automatically create lines & areas when
coding’.
LSS uses the ‘Begin Line’ setting in the
‘Linework’ tab to automatically recognise a
start of string. It must be set to the default
‘BEG’. Alternatively the LSS start string ‘.’
character could also be used.
7. ‘Quick Code’ is currently ‘Off’ although the
prototype code list has been set to use 3 digit
codes if switched on.
The ‘Store free code’ is set to ‘Before pt is
stored’ which means all Free code [F7]
additions made before a shot apply to that
observation.
Page 16 of 58
My Survey Screen Settings
The ‘My Survey Screen Settings’ shows the Code and its description along with up to
five associated attributes (as used by the example prototype tree feature PD). Use the
scroll bar to reach the last attribute.
To create these settings choose ‘User’ from the main
menu and then ‘Work Settings’, then ‘My Survey

Session 2
Duration:
2.1
Survey Practical Exercise
1 hour 30 minutes
The following plan and accompanying coding document have been designed so that a
practical exercise can be carried in which to practice some of the latest techniques that
have been developed in conjunction with Leica System 1200 and Viva instruments.
These include general feature coding, the use of string numbers and the ‘.’ and ‘..’
special codes, feature attributes on the instrument and reserved codes used to generate
additional observations in LSS. It is quite a condensed survey so be prepared to take a
bit of time to acclimatize yourself with how the feature and other coding is applied on the
instrument.
Before we go outside, we will
just go through codes used in
the exercise and then explain
how to start a new survey job on
the survey instrument.
The rough guide,
‘Feature coding for Land &
Eng. Surveyors’.
Titled “Principles of Survey and
Feature Coding”.
can be found on the LSS
Installation DVD or the Website,
is a good reference.
We will go through the pdf.
Page 19 of 58
In the plan below the numbers refer to the point identifiers, marked on mini sports
cones, which are to be the point ids on the instrument.
The black numbered observations are the ones to be surveyed; whilst the blue numbered
observations are those representing extra points created by using the LSS reserved
codes, described fully in the rough guide.
The table on the page opposite, to be taken outside along with the plan, is an itinerary of
the codes to use on the instrument in order to make use of the coding options during
Input Load in LSS.

Instrument Data Capture on a Leica 1200
Creating a new 1200 job

Select option 1 Survey from the Main Menu to
access the Survey Begin screen.
Note: Select by pressing the number 1 key, or by
navigating to 1 Survey and pressing the Enter key,
or by touching the Survey icon when using an active
touch screen.

Select the Job list and Enter.

Select New

Type in the Name and other settings for
General.

Also set the Codelist, Coord System and the
Averaging settings. Then Store.
Note: If only one Codelist is in use on the
Instrument then it will be the default.

Returning to the Survey Begin page, the Coord System, Codelist and Config Set
should be set for the new survey e.g. as per the LSS CD ‘Support files’ folder.
Note: When using a TPS the Setup needs to be
selected from this page unless no co-ordinate
information is required during the survey. In which
case use the Free Code ‘Setup Fr’, and the Point
codes ‘Setup Pt’ and ‘CTLObsRO’ to store the Setup
and control obs information for LSS purposes only.
Note: CTLObsRO may also be used following a
CTLObsID when multiple control obs are required and
recorded average is to be avoided.
Page 22 of 58
Setup procedure
The following example assumes an arbitrary co-ordinate system. If existing control
coordinates are needed the stations can be uploaded from LSS to a Fixpoint Job (see
exporting data from LSS to Leica 1200) and then copied to the current job before doing
the first set-up using ‘Convert’ [4] then ‘Copy
Points Between Jobs’ [3]
Press SETUP [F3] to input the details and observe
the baseline stations.
For Method choose Set Azimuth to supply an
arbitrary bearing.
For Station Coord use ‘From Job’ rather than ‘Frm
Fixpoint Job’ (see first paragraph above).
Select the Station ID to select or enter a new station
(as shown) Enter the Instrument Ht.
If you have selected a new Station ID the New
Point screen will be displayed for co-ordinate entry.
Then press STORE [F1].
Press CONT [F1].
Select the Backsight ID
Enter the Reflector Ht.
Click Az=0 to set the HA to 0
Press DIST [F2] to measure the distance to the RO.
Press SET
The Instrument confirms that the Station and
Orientation has been set.
Press OK [F4].
You are now in the detail measurement screen.
Control Observations
For a control observation highlight the Point ID and
press Shift INDIVID (avoids the incrementing Point
IDs), then enter the station ID
For Code select CTLObsID and take the shot - do
NOT use the –ST Reserved code.
Page 23 of 58
Detail procedure
For basic measurements centre the TPS1200 accurately on the prism at your detail
point, set the Point Id (e.g. to 1) and press ALL [F1].
If the ATR is being used the Total Station needs only to be aimed approximately at the
prism.
If LOCK is being used the Total Station will “follow” the prism as it is moved from point
to point.
The DIST [F2] and REC [F3] keys can be used instead of the ALL [F1] to measure an
object that the prism cannot occupy the centre of (e.g. a pole).
The prism is placed next to the object and DIST pressed to measure the distance and
place it in a “buffer”.
The instrument is then turned so that the centre of the object is bisected and REC
pressed.
Note: that LOCK must be disengaged to use this function.
Detail Coding
LSS uses Point coding and Free coding. The Codes
are accessed via the display entry ‘Code’ and the
Free Codes via the ‘Select Free Code’ [F7] key.
In each case the relevant part of the Code list is
displayed as exported from LSS
(see the LSS DVD ‘Support files’ folder).
Using the arrow keys highlight the ‘Code’ entry and
type the required code or ‘Enter’.
The codelist will appear defaulting to the closest
entry to the typed characters. The arrow keys can
further be used to manually select the required code.
CONT or ENTER will return to the display mask with
the highlighted feature code.
Page 24 of 58
Attributes
Attributes are integer, real, text or choice-list values
used in certain features in the code list and behave
in the following way:
The Code Display mask will show the required
attributes for the selected Point feature code.
It is necessary to use the ATTRIB button on the
code list to change an attribute that is not set to
mandatory.
For the Reserved codes this applies to –REC and –RIN.
Where Attribute 1 is the string number it can be left blank and a new string is started
each time the code is ‘toggled’. This is true even when the code remains the same.
Free-codes
The Reserved codes, e.g -REC. are all referenced as
Free-codes via the [F7] button and behave in the
following way:
A Free-code is additive to the Point code currently in
use, i.e. ‘As well as’ , NOT replace.
Free-codes can be stacked, e.g. Notes and –REC can
be added on a single shot.
Note: Not all combinations work.
A Free-code applies to ‘One shot’ only as it only applies to the current observation and
does not appear on subsequent measurements.
The LAST button will show the last used codes in order.
Page 25 of 58
Subsequent set-up procedure
When it is
a.
b.
c.
time to move to a new Survey Station;
Press ESC to leave the Survey: screen
Press ESC to leave the Survey Begin screen and return to the Main Menu.
The TPS1200 can now be turned off.
At the new Setup, switch on the instrument and use
the SETUP [F3] option in the Survey Begin screen
to enter the Station Setup screen where subsequent
set-ups on a job assume a coordinate system using
the existing Station coordinates.
For Method you can now choose Known BS Point.
For Station Coord choose From Job
For Station ID select or enter an existing station
Enter the Height of the Instrument.
Press CONT [F1] to go to the Set Stn & Ori – Known
BS Point.
Select the Backsight ID and enter the Reflector Ht.
The instrument will report the calculated azimuth and
horz dist.
Press DIST [F2] to measure the distance to the RO.
Press SET
The Instrument confirms that the Station and
Orientation has been set.
Press OK [F4].
Important Note:
Never insert or remove the Compact Flash [CF] card unless the System 1200
sensor is switched off. If there is data access to the CF card when removing or
inserting it, your files may become damaged.

Station name) and the relevant arbitrary coordinates.
Specify a ‘Backsight ID’, ‘Target Height’ and
‘Direction’
Sight the target, then press ‘Dist’ then ‘Set’
You are now ready to start detailing.
Page 28 of 58
Detail Procedure
LSS uses Point, Point with Line and Free coding. The Codes are accessed via the display
entry ‘Code’ and the Free Codes via the [F7] key. In each case the relevant Codelist is
displayed as exported from LSS (see the LSS CD ‘support_files’ folder).
From the ‘Go to work’ menu select ‘2 Survey’
In the ‘Code’ option click the list icon
Using the arrow keys highlight the ‘Code’ entry and
type the required code or ‘Enter’.
The codelist will appear defaulting to the closest entry
to the typed characters. The arrow keys can further be
used to manually select the required code.
‘OK’ will return to the display mask with the
highlighted feature code.
Attributes - The display mask LSScod will show the
required attributes (either integer, real, text or choice
list) for the selected feature code.
Note: The LSS default for mandatory attributes is
‘Only on code change’.
The default values as set in the codelist.
Note: The current feature remains active on repeated measurements.
Note: It is necessary to use the ATTRIB button on the code list to change an attribute
that is not set to Mandatory as per reserved codes, -REC and –RIN.
Note: The LAST button will show the last used codes in order.

Smart coding
To turn on Smart coding at this stage click the
CONF and set the values as listed;
Use SCodes – Yes
Measure point - No (this can be set to Yes during
the survey to automate the data collection by
selecting Shift CONF)
String Attrib - 1 (this is linked to the Coding and
Linework config set values and should at this stage
already be 1). Note: 1 must be used.
Method - Not Used (Zig-Zag and Same direction can be used if required)
Note: The following details follows after the Setup during the detailing procedure:
When you arrive in Survey mode the SCode tab
should now be available as shown.
Highlight the first Code box by selecting it and
press the Codes button [F3] and select your first
code from the codelist.
Note: String numbers need to be used and can be
added to the entry point directly below each
feature.
Repeat for each box until a complete set of codes
are listed.
Additional code blocks can be created by
highlighting the existing code block name e.g. 1,
press Enter and choose a New [F2] name and
Store. Then repeat to add codes for the new block.
In this way additional code blocks can be created
until all required code block templates have been
defined.
The + or – buttons can be used to increase or
decrease the string numbers.

Session 3
Duration:
1 hour 30 minutes
3.1
Configuring the Leica 1200 / Viva Datalogger in LSS
This is a once-only operation, for each type of instrument to be used, on every
computer into which data is to be downloaded.
To configure our logger of choice in LSS we select Configure Hardware & System,
followed by ‘Logger - New’ (if this is already another logger configured then the option
will be ‘Logger / Change’). Now we need to choose the format of the data.
We will configure LSS for a Leica System 1200, for which the recommended method is
to use Leica’s 1200 DBX Database Reader to access the list of jobs on the instrument’s
memory card and which should have been installed in Session 1.
Select the logger format as
‘Leica’ and give the description
as ‘1200’.
Next we choose the usual data transfer / download method.
The option ‘System 1200 DBX database
reader’ allows direct access from the
instrument job files on a drive e.g. Compact
Flash card.
Active Sync sets up a drive,
We can send from the instrument,
Or use Leica Geo-Office Tools.
If the .SVY file already has been copied to
the C: drive, we can tick ‘No
transfer/download by default’.
Hitting ‘OK’ will allow us to ‘Finish’ and ‘Save’ our logger settings.
Note: This must be repeated for all PCs likely to be processing Leica System 1200 data.
Once installed and configured, the DBX Database reader will read the card and the list of
jobs will appear in the next window. The Database reader will then put out an ascii file
with the same job name but a .SVY extension, and it is this data file, in Leica GSI
format, that LSS is able to read and convert.
Page 32 of 58
3.2
Configuring the New Survey Parameters in LSS
For each survey the following parameters are set during what is termed the “survey
initialisation” process, which is the starting point for all surveys.
The command Configure Hardware & System - New Survey Parameters allows
many of these options to be set in the following window:
Set the Handling of 2-D data,
Alter standard Annotation of
Levels for hydrographic surveys.
The Drying height is the height
above Chart Datum to be
considered as ‘tidal’.
Set Survey units for length, area
and volume in the survey,
And other survey parameters:
Angular units, Obs format,
Vertical angle collimation.
We set Control tolerances,
And maximum and minimum
Target heights,
File and Obs numbers for
Inserted observations.
‘Default Scale factor’ - this value does not affect any distance calculations directly but is
used to provide a default scale factor to newly loaded or edited stations to relate radial
survey observations to their grid coordinates.
The value is normally be set to ‘1.0’, but, Note: GPS data (including stations) based on
the OSGB36 TN02 transformation should have the local scale factor applied here.
‘Curvature / refraction adjustment’ - will apply a fixed correction to radial survey data.
The difference in level between adjusted and non-adjusted observations amounts to
7mm in the first 1km, rising to 7m at 10km, so is rarely of concern for most surveys.
‘Conditioning tolerance’ - applies to arcs and circular steps - either surveyed or Co-Go
generated - or when ‘Output smoothed links’ is used.
‘Angles format’ – all survey data is displayed in this format and can be changed.
‘Obs format’ – cannot be changed once radial survey data have been processed. It is
possible to have different formats contained in loadfile(s), but after being processed all
survey data is displayed / reported in this format.
‘VA Collimation’ - sets the default Vertical Angle at horizontal- either 90° or 270°. LSS is
able to process combined Face Right and Face Left station observations.
‘Control tolerances’ – refer to the survey data processing of control observations. When
a control (station) observation exceeds the warning or error values it is reported.
However, when an error is issued the survey processing will be terminated as well.
It is the responsibility of the surveyor to be aware of these settings.
Note: It is possible to use negative target heights for when the detail pole is inverted,
but exceeding the set values will also issue a warning.
Page 33 of 58
3.3
Configuring the File Editor in LSS
Programmer’s Notepad File Editor (PN) installed earlier from the LSS DVD is a program
that we have found ideal for editing large files of data that are in Ascii (text) format.
The program can also be downloaded from the LSS Website.
After installing in C:\Program
Files(x86)\Programmer’s Notepad, we
choose Configure Hardware & System –
File Editor.
We can select ‘Other’ and ‘Browse’ to the
file in the C:\ drive;
Once configured, any text file used by LSS
which has an ‘Edit’ button available will be
opened with this file editor.
Once we have adjusted our ‘New Survey
Parameters’, and File Editor
(or, indeed, any of the Hardware and
System settings), we will be prompted to
‘Finish’ and then ‘Save’ the settings:
We can ‘Save’ the Configuration changes, or
‘Use changes – save / discard on exiting
LSS’ will only retain the settings for this
session, although a further prompt will allow
us to save when we quit LSS.
‘Discard- revert to last saved settings’ will
simply discard the recent system changes.
We are now ready to process our practical exercise survey in a new LSS survey.
Page 34 of 58
3.4
Creating a New Survey in LSS
A survey must be open to process data into LSS and we will do this exercise in a new
survey.
Select File New from the main
menu.
Click Browse against ‘New
survey’.
Create a new folder for the new
survey to go in and call it e.g.
C:\ Surveys\Workshop;
Select it in the ‘Save in’ box
Enter the survey name, e.g.
‘Workshop Survey’
to ‘File name’.
Click ‘Save’.
This will return to the ‘File New’
dialog with the path and name of
the intended LSS survey.
Enter Survey title (if left blank
LSS will use the survey name).
The ‘Prototype’ will be as per
‘New Survey Parameters’ (see
above).
If we had stations already at the
site we could bring them in here,
We will set the survey so any 2D data will go to the survey’s
Non-terrain.
Tick ‘Configure Survey
Parameters’, then
Click ‘OK’
Page 35 of 58
Ticking the ‘Configure Survey Parameters’ allows us to revisit the parameters set
during the initialisation process, and we would not normally require this:
Or this window can also be invoked by the command Configure Survey Parameters.
But if we continually have to reset a particular parameter, then it might be worth
reconfiguring the New Survey template values.
Note: the LSS Prototype is found in Testdata and also in Prototype directory, and either
can be used here. Testdata is set here because this is where all the training datasets are
held.
It is assumed that the surveyor will look to create their own prototype for their features
in say C:\Surveys\Prototype and so will not be accessing the original LSS prototype in
Testdata.

It is often convenient, as we have done here, to create a new survey before
downloading or transferring any survey data across from the survey instrument – in this
case the memory card of the Leica 1200. But as the flow chart above shows, it is
possible to download and convert whilst in another survey.
Page 37 of 58
Data processing – Input Download / Convert
The first task is to transfer the Leica 1200 memory card from the instrument to the card
slot on the pc or card reader, once it is safe to remove from the instrument.
Selecting Input Download / Convert will invoke the Download data window, the
variant shown on the right being displayed if we have not already configured a logger
which prompts us to do so by clicking ‘New’ and following the dialog boxes:
Either way we will need to save the logger configuration settings in the system registry.
Note: The ‘No data transfer/download tick box can be selected if the survey data has
already been copied across to the hard drive of the computer.
Clicking ‘Next’:
Select the System 1200 job data folder on the memory card inserted into the card
reader by either
a) Clicking Browse to locate the folder and Click ‘OK’, or
b) Click ‘Explorer’ and find a file within the folder and ‘drag and drop’ into the Job
folder dialog.
Page 38 of 58
Clicking ‘OK’ to the selected Job folder will provide a list of the System 1200 jobs in that
folder. You should find a list of surveys in the following window, so choose the required
job and click ‘OK’.
This dialog confirms relevant information on the selected job;
The name of the download file to be transferred will default to ‘job file name.SVY’
The data type to be downloaded defaults to the recommended instrument raw data in
‘EDM radial and/or GPS coordinates’.
The option ‘All data as coordinates (no QA)’ will process the job as instrument calculated
coordinates with no checks.
‘Archive DBX job database’ will copy the database files to a sub-folder of the current
survey.
Note: The job database files (DBX) are not expected to be ‘archived’ if they are already
in a folder under the current LSS survey folder tree and the option will be greyed.
Note: It is recommended that at least ‘None’ is selected; this will then include those
observations taken to remote heights of features (the –VA Reserved code), which are
classed as ‘None’ on the instrument.
Click ‘OK’ and the data transfer will now occur and LSS will display the data conversion
dialog on completion.
Page 39 of 58
We should be prompted to the next Input Download / Convert – Conversion of Leica
– LSS default window.
Make sure the LSS load file input box is empty and Click 'Next'. LSS will automatically
provide the next available load file number for the current survey, i.e. WORKSHOP
SURVEY.001.
Leave the other settings as per default (the processing of data into LSS is covered in the
‘LSS for Surveyors and Engineers course including quality control, error analysis and
feature code conversions)
Click 'OK' and LSS will attempt to convert the data.
If during the conversion LSS detects a
feature code that it does not recognise in its
legend a 'Feature conversion' dialog will
appear to allow the coded feature to be
converted.
The user is then prompted to accept the
code, change it to one that is known or
change it to a recognised ‘Special’ or
Reserved code - more of which later.
Note: ‘OK’ will maintain the current code
and ‘No more feature code conversion
requests’ will ignore all future unrecognised
codes.
Page 40 of 58
If any feature conversions have been responded to during the data conversion (other
than the choice ‘No more feature conversion requests’ on the first dialog) then at the
end an option to save all the feature conversion responses as a file will be offered.
At completion we see the conversion report window which shows the number of
converted stations, set-ups, observations, text etc and whether used or unused.
This review is well worth checking to make sure all the observations have been
converted and loaded, and (especially) the number of Set-ups is correct.
On choosing ‘OK’ we will be prompted to ‘Save and Load’ the newly created load file.
Or we can ‘Save’ and
continue with
converting other data
files,
Or ‘Delete’, if problems
have been encountered,
or we forgot to use a
conversion file.
Click ‘OK’
The 'Save and LOAD file' option will automatically invoke Input Load and highlight the
newly created load file.
Note: If the load file name is for a survey that does not exist then the ‘Save and Load’
option will prompt File New to create a new survey prior to Input Load.
Page 41 of 58
Data processing – Input Load
Introduction
The ‘LSS Load Input file’ is the format by which all external data is processed into LSS
e.g. data from a survey instrument has to first be converted to a load file via the Input
Download & Convert option.
Loading data into a survey model
The Input Load command will invoke the following window, highlighting the correct
load file i.e. ‘.001’ if ‘Save and Load’ has been chosen.
A Load Report
file will be
generated – we
select the file
type.
Leave the
options as per
default and click
'Next'.
If the survey is empty and no station
coordinates are provided prior to the first
instrument set-up in the Load file, then an
Initial Set-up dialog will be presented to
verify the station coordinates and
orientation.
Click ‘OK’.
Otherwise the station coordinates from the Leica instrument are loaded along with the
detail.
Clicking the ‘Edit’ button next to the Load file 001 will open the load file in Programmer’s
Notepad, if this has been set as the File editor, The Load file can be viewed and edited
to address any issues raised during Input Load.
Page 42 of 58
An explanation of the LSS Load file format
A load file can contain either radial observations, coordinate observations or both, which
can be opened in Programmer’s Notepad;
Radial and coordinate record types
0 = Comment line containing information that will not be processed by LSS, such as the
surveyors name, data and time of the survey.
1 = Parameters record containing e.g. survey units and angular settings.
2 = Station coordinate record.
20 = Station coordinate control observation used as a check and commonly encountered
with GPS survey equipment to verify a survey station position.
6 = An item of general annotation (normally text entered on a survey instrument or
logger as a comment or note). Such annotation will be shown in the LSS survey centred
on the previously surveyed point.
9 = End of file marker. It is not necessary to have one of these at the end of the file.
Radial only record types
3 = An instrument setup record with set-on station, followed by backsight station,
backsight angle, instrument height, vertical angle collimation and station scale factor.
Some of the fields may be blank as in this load file as LSS will be getting information
from lines which follow.
4 = A control observation where the final field is the station name. If there is a 4 record
following a setup record, this will provide any missing information in the setup record.
This is identical to a ‘5,’ record with a ‘-ST’ code.
5 = A ‘detail’ record which contains an observation to a surveyed point with the feature
code appearing in the last field. Multiple features may be specified and separated by
either a comma or a forward slash.
This record type may also be a control observation, where ‘-ST’ is the code, with the
station name either following this or being taken from the observation number field.
We may also use the special or Reserved codes, described in detail in the next session.
Coordinate only record types (not shown in this example)
21 = A coordinate record. Instead of collecting radial data it is possible to collect and
convert coordinates, e.g. for GPS survey data. These survey data can also use Reserved
codes.
Page 43 of 58
As the load file is processed so a report is produced showing all relevant information e.g.
comments, setups and control observations. Any warnings or errors found in the data
set will cause the processing to pause. An error will not allow Input Load to complete.
The end of the Input Load Report should appear, with a note
*** Warning(s) issued *** recognising that some warnings had been issued.
Any misclosures that exceed the ‘warning’ parameter are labelled Large differences,
and Load will pause. Likewise for any that exceed the ‘error’ parameter except that
here Load will not complete.
If we scroll back up the following report file, we might find ‘Warning : Feature does
not exist.’ and ‘Warning : Large Difference.’ Warnings have been generated during
the Input Load process. Otherwise, click ‘Continue’ to update DTM and ‘OK’ to close
window.
If a loaded feature is not found in the Legend, then the ‘Warning : Feature does not
exist.’ is created. We will also be prompted to save new feature selections to CNV file.
For each control observation, the combined 3D measured ‘slope distance’ is compared
with any stored values and tested against the ‘Control Tolerance’ warning and error
values set in ‘Survey Parameters’.
Those control observations with ‘Warning : Large Difference.’ next to them, are
where the warning tolerance (0.01m) was exceeded (but not the error tolerance).
Note: if an observed station does not exist in the survey, then the first observation is
used to compute its coordinates – they are not meaned here. Subsequent station ‘shots’
become ‘check’ observations’.
Note: if any errors are encountered the load will not be permitted. It will be necessary
to review these errors and maybe respecify the error tolerance to allow the load.
Often errors occur simply because the stations have been incorrectly labelled during the
set-ups, or there is one poor observation.
To correct these click ‘Back’ and then ‘Edit’ to open up the load file. If you have set ‘PFE’
as your editor program then use ‘CTRL+G’ to go to the line directly.
If available, Click 'OK' to continue and 'Continue' to complete the load and display the
data. This includes updating the triangulation to create the DTM.

On the screen, the loaded survey should look like the screenshot:
Note: Attachments in the form of images have come through from the survey data.

3.6
Leica 1200 format file
In normal circumstances the format file is not required for the 1200 when using LSS
because the DBX Reader replaces the need for its presence on the instrument. However,
if it does become necessary to use a format file it is important that the right one is used.
The correct one can be found on the LSS DVD in
“\support_files\leica\1200\format\lss1200.frt”
You will need the LSS format file if;

There is not a working version of the DBX reader available
In this case copy the format file to the CF Card and then Transfer it from the CF-card
to System RAM using the similar procedure to transferring the code list shown
earlier.
Then from the main menu choose 4 Convert then 1 Export Ascii and then select the
LSS format file.
This will create a file identical to the SVY file created by the DBX Reader and can be
copied to the PC.
Following the processing sequence shown earlier just tick the box ‘No data
transfer/download’ which will skip the DBX reader and then Browse the exported file
as ‘Downloaded file’ in the conversion dialog.

There is a need to post-process the DBX data in Leica Geo Office.
When using conventional GPS it may be necessary to post-process the observations
with Rinex dat in Leica GeoOffice. In this case use the option ‘Export / Ascii‘ with the
following settings;
a.
b.
c.
d.
e.
f.
Filetype Custom Ascii
Right click on New Settings – Add name
Settings button
Coord class – Current
Sort by – time i.e. not Point ID
Format template: use LSS1200.frt from the
“\support_files\leica\1200\format” folder on the LSS CD.
g. Deactivated points – ‘turn off’
h. In LSS ‘Input / Download and Convert’ select ‘Data transfer/download not
required’ and on the following conversion dialog Browse the ‘downloaded file’
from LGO.
Note: This will not include the free codes.
Page 46 of 58
3.7
GPS Survey Instrument Issues
GPS data can be read directly from the 1200 DBX database as long as the GPS
coordinate system has been fixed either;
An O.S. Grid ‘OSTN02(GB).CSC’ and ‘OSGM02GB.gem’. The LSS DBX reader also
supports the use of OSGM02NT.gem and OSGM02RI.gem files for Ireland.
Note: During the Input Download / Convert process LSS will report if a job is using
CSCS or GEM files on the job list.
Or as a local grid via a coordinate transformation or a fixed base station and the levels
relate to Orthoheights.
Scale factor
If the GPS coordinate system contains a scale factor then LSS can combine this GPS
data with radial (EDM) data in the same LSS model.
Do this by setting the “TPS corrections / GeomPPM / Calc Scale” to Automatically in the
configuration set.
This enables LSS to read the scale factor at each station coordinate and hence process
the radial data with the correct scale factor.
There is now a new Transform option that applies/removes the scale factor in an LSS
survey as long as all the raw observations have been first transformed to their
calculated XYZ coordinates first (File Transform - Observations to XYZ).

Session 4
Duration:
4.1
Exporting data to the Leica 1200 / Viva Datalogger
1 hour 10 minutes
LSS exports data to most types of survey instruments using the same logger
configuration as Input / Download / Convert.
From the main menu the export commands are listed under Export;
For survey instruments the key exports are:
‘Onboard instrument DTM...’
‘Upload data to survey instruments...’
‘Upload code list to survey instruments...’
‘Leica DBX Database’
A useful generic alternative is
‘XYZ (.CSV)...’
Or
‘LandXML...’
Choose which is the most appropriate for you particular logger.
The generated files are copied across the instrument card or USB data stick ready for
transferring to the Leica.
For the Leica System 1200, Viva and Nova, we can ignore the Onboard instrument DTM
option, since this will be included in the Export Leica DBX database.
Export LandXML is currently being developed in LSS Beta for the next main release, so
we will ignore it for this course.
Page 49 of 58
Exporting Data direct to the Leica 1200 Datalogger as a Leica DBX File
New to LSS V9.90 is the option to export direct in DBX Database format, which is the
most convenient option for the Leica System 1200 platform instruments;
From the main menu, select
Export Leica DBX database.
Specify a name for the exported file
and click
Standard survey’
Note:
DTM and
Road (alignment SPF) are also
available.
‘OK’
LSS will export the entire survey into the necessary DBX files which are copied onto the
instrument card job folder via the card reader.
With DTM, the DBX files are placed in another subfolder.
Page 50 of 58
Exporting Data as a Leica GSI File
Note: The logger parameters
can be altered by clicking
‘Change’ or by using Configure
Hardware & System / Logger.
Specify a name for the exported
file and click
'Next'.
This dialog allows the selection
of observation and station data.
The defaults assume that the
‘Observations’ will be exported
using the Selection filter. Click
‘Next’.
Note: The observations can have the code added to the point number, which can be
related to the SPF chainage.
If chosen the Selection filter
dialog will offer the opportunity
of multiple observation selection
criteria.
Hit ‘Apply’ to make selections on
the screen – there can be many.
As soon as there are
observations selected then the
'Cancel' button is replaced by
‘Finish’.
Click ‘Finish’ once all required
data is highlighted.
Note: The data selected by the Selection filter is grouped in the export set first as
complete strings and then as individual points related to their loaded order. To export
the observations in the order they were located use ‘Individual observations’ from the
previous dialog.
There is the possibility of repeating several
selection criteria to the same data set.
If required, we can click ‘Add more data’ and
repeat the process.
We might choose this option to export Survey stations or specific observations.
Page 51 of 58
4.2
Exporting an LSS Code List to a Leica System 1200 / Viva
The LSS option ‘Export Upload code list to survey instruments’ will produce a Leica
1200 code list. However, we suggest that for new users the LSS prototype legend
(supplied with Testdata on the LSS DVD) is used as a standard starting point for which
there is a pre-built Leica 1200 code list available in the ‘Support Files\Leica\1200
series\Code list’ folder of the DVD. Please refer to the ‘Transferring a code list…’ in
Session 1 above that explains how to copy these files onto the device.
As a consequence it is suggested that the Export code list option is best used for sending
new additional features to the Leica 1200 code list as they are added to the LSS
Prototype Survey. Follow the process below to create a new code list in Leica Geo Office
and then cut and paste the new features to the existing code list before placing it back on
the instrument.
Within a survey containing the prototype legend use the option’ Export Code list to
survey instrument / Leica’.
Provide the filename for the code list.
Use LSS to generate the IDX code list
Note: It is suggested that no path is provided i.e. no backslash, so that LSS will save the
file in the current survey path. When imported to LGO this will also then become the
path for the LGO database files.
Page 52 of 58
‘Select’ the required point features.
Tick the ‘Use trailing digits as dimension attributes’ under Points if there are dimension
items e.g. PT1, PT2, …,PT20 etc. This will allow LSS to export these as a single feature
with a Mandatory integer attribute for a more efficient code list.
Note: It is important in this instance to have an extra feature without the numeric suffix
e.g. PT, within the legend so that LSS can convert the items cleanly during the survey
processing.
‘Select’ the required link features.
Tick the’Include attributes for string numbers (links only)’ under Links if required. This
will add a Normal integer attribute, with a default of 0, so that each link feature can have
a string number if required for multiple string coding management.
Leave the ‘Extra LSS codes’ box ticked to create all the Reserved codes as Free codes.
Note: This option will also export the ‘String codes’ and ‘Code words’ code groups that
contain a mixture of free and point codes for extra functionality. OffsetLR, OffsetFB and
OffsetUD are identical to the relevant reserved code offsets and SetupFr, SetupPt and
CTLObsRO are for use when not using the instrument set-up and coordinate menus. The
primary String codes and Code words are;
‘CTLObsID’ – for point coding a control observation for the instrument and LSS
simultaneously.
‘Notes’ – for adding general text at an observation
‘Freecode’ – for adding multiple codes to one shot only
Start a new string from the previous point
The reserved codes as a group
The ‘Tree feature’ requires two Point features with digit suffixes for dimensions, the first
feature represents the spread and the second the trunk e.g. PD1 and PS1.
Note: The Tree feature has several attributes combined to make it a tree function
including adding height and species information as well as the spread and trunk.
Select TPS1200 and click ‘OK’.

Leica Geo Office – Importing an LSS Codelist from an IDEX file
Click on the Codelists icon to open the Codelist
Management screen in Leica Geo Office (LGO).
Click on Codelists under the Management pane.
Right click on the mouse in the Contents panel,
which contains the Codelists folder.
Select Register… option to open the Register
Codelist panel.
Browse the IDEX file folder.
The file name will in line with
Name:
Note: Once an IDX code list has been imported its
name will appear duplicated on this list but without
the IDX suffix. Always chose the name with “.IDX”
Click on the drop down arrow to the right of the top
line if there is more than one suitable file in the
folder.
Once the correct file name is displayed in the top
line, click on OK to Register the IDEX file.
A dialog will appear saying ‘Register codelist from
IDEX’ with a warning that the IDX file will not
maintain the changes in the code list edits.
Use the pull down arrow to the right of the
Instrument Class: field and select the Instrument
Class that the Codelist is for i.e. SYSTEM1200
Leave the Type: field as Advanced.
Click OK.

The new Codelist will be displayed in the Contents
pane with the same name as the IDEX file. If you
wish to rename your Codelist, right click on the
Codelists file name and select Modify…
Note: There is a limit to the amount of code list
information that can be imported via an IDX file. If
necessary Points, Links and Extra LSS codes can be
exported separately from LSS and Cut and Paste
from separate codelists into your prototype within
LGO.
This is the LSS suggested way of creating code lists:
i.e. cut and paste newly exported features into the
existing LSS prototype code list after deleting those
codes that are not required.
Clicking on the + next to
the file name will display
the Code Groups.
Clicking on the + next to a
Code Group will display the
Codes in that Group.
The exported link codes from LSS require
the Linework setting amending.
To do this, left click on the Links group to
display all the exported links in the right
hand pane.
Then in the right hand pane right click on each link feature and select Properties.
Change the Linework from None to Start (This applies to v5 firmware format upwards).
The right hand end of the dialog will now show the additional properties e.g. Lins Style and
colour which can now also be set.
Important Note: The LSS prototype code list LSSv9_80 on the LSS DVD has been
generated from the LSS prototype legend and has had all the above work already applied
and is ready to put straight on the instrument.
If you require to amend this code list and/or export an IDX code list from LSS you will need
to have Leica Geo Office installed (LGO Tools v6 is available on the LSS DVD).
As an LSS user you only need direct use of LGO for the Code List Manager and only then
when you wish to amend the prototype codelist supplied with LSS. Other examples of code
lists have also been provided e.g. LSSv980Road and LSS1200Adv, to give examples of
what can be added to a code list.

Advanced code list use - example code list LSS1200Adv
To shorten the number of items on the main code list but maintain the same number of
codes in the code list overall;
If a feature code
has the two extra
characters “>>”
added LSS will
ignore it on import.
This code will have
2 attributes.
The first attribute can then be made to be
the feature code that LSS will use (in the
example code list shown this attribute has
been used as a choice list of all the
fences).
As can be seen on the first diagram the
second attribute will be the string
number.
In order for the stringing to be seen on the Map you will need to change the coding and
linework String Attribute setting in the config set to 2 (as in the example code list it is
better to change all the codes in this way so that they will all appear on the Map).
Where a code does not have a main code with “>>” it is necessary to introduce a blank
attribute so that the string number is still attribute 2.

In this final session, you should now have an understanding of:
a) Exporting data to a file to upload to the survey instrument.
b) Exporting an LSS Code list to an Idex file.
c) How to use Leica Geo –Office Tools Code List Managerand to append codes to
an existing code list
d) The Advanced code list.

Conclusion
In this workshop we hope that you will be in a position to start making the most of the
survey instrument, feature coding in the field, transferring survey data and design data
from and to the survey instrument. We have looked at the LSS Reserved codes and
using LSS to coordinate and check the survey control stations.
We should have covered a good deal of the options, but there are always new possible
methods and developments so do keep in contact by visiting the LSS Help and other online resources, such as the “LSS Online” Forum and calls to our support line. You should
very quickly become comfortable using LSS and feel able to apply what you have learnt
today to undertake a wide range of survey and engineering tasks in the future.
