Leica ALS80
Airborne Laser Scanners
Performance for every Application
Three Models, One Result.
Highest Productivity in all Applications.
Imagine an affordable city-mapping LIDAR system with an
industry-leading 1.0 MHz pulse rate, capable of meeting
your specialized needs now, and that is easily upgradable
to a full-capability configuration as your business grows.
Imagine producing high density point clouds for corridor,
urban, flood plain or general-purpose airborne mapping in
a fraction of the time it took previously.
HP
HA
Leica ALS80-CM is designed for city and
corridor mapping applications from lower
flying heights. Ultra-high-density can be
achieved by flying in small aircraft or
mounted in helicopter pods, taking
advantage of the low-profile scanner.
Leica ALS80-HP is designed for generalpurpose mapping at the flying heights
most widely used, and can accommodate
greater terrain relief due to its higher
maximum flying height.

The Leica ALS80 is a single family of systems that offers
this level of flexibility and productivity, without compromising on quality and accuracy. Three models, Leica
ALS80-CM, Leica ALS80-HP and Leica ALS80-HA, share
a common platform (high-performance laser, scanner,
range counting electronics, position/attitude measurement subsystem and user interface, flight planning and
execution software), to create a range of laser scanners
Two Laser Scanner configurations and two System
Controller configurations are combined to create the
three models in the Leica ALS80 range:

Need room to grow? No problem.
The unique modular design of the Leica ALS80 offers
numerous benefits, including easy growth options.
Did your business start with lower-altitude corridor
mapping, but is expanding? Any Leica ALS80-CM can
become a Leica ALS80-HP at the user’s site. Need
truly high altitude performance? Leica ALS80-CM and
Leica ALS80-HP can be factory-reconfigured into Leica
ALS80-HA and vice versa. Expanding your business into
forestry and environmental areas? Add the optional Full
Waveform Digitizer at any time, at any location.
Leica ALS80 – a total package
Leica ALS80-HA is a high-altitude variant,
allowing the market’s highest flying
heights, for wide-area mapping on a
state or national level.
Leica ALS80 systems come complete with peripheral
products and software that provide a seamless workflow
from mission planning through point cloud generation.
Point Density Multiplier – the key to high productivity
Point Density Multiplier is a combination of optical and
electronic technologies that allows a quantum increase in
measurement and scan rates over that available in
single-output scanners.
All models in the Leica ALS80 range feature a revolutionary new system control and range measurement module.
This new module significantly reduces range measurement
cycle overhead, allowing pulse rates that approach the
maximum theoretical limits and yielding higher pulse rates
at any given altitude. In addition, this same measurement
technology makes the proven MPiA feature even easier to
use. Additional features of Leica ALS80 include:
nn Unlimited range returns from each outbound pulse for
greater detail in forest canopy
nn 20 % reduction in inter-return range separation for
better ground detection in low vegetation
nn 25 % reduction in circuit board count for increased
reliability
nn 3 user-selectable scan patterns, sinusoid, triangle and
raster, for unrivaled control over point pattern
nn AutoScan: automatic adjustment of scan rate to
keep more uniform along-track spacing as aircraft
speed varies
nn Optional fully-integrated Full Waveform Digitizer (FWD)
for waveform data collection at up to 120 kHz
Mission planning and system control
Planning for all Leica ALS80 models is accommodated
using Leica MissionPro planning and evaluation software,
including optimizing both system settings as well as flight
line layout. The intuitive AeroPlan pull-down menu allows
manual or automated optimization of system settings in
three ways:
Choice of sine, triangle and raster scan patterns
Leica ALS80-CM and Leica ALS80-HP models also
feature a unique multiple-output scanning system.
This new scanning approach allows the system to double
the pulse rate and scan rate of single-output systems,
without the use of multiple scanner assemblies or lasers.
The elegance of this implementation adds to the stability
and consistency of the high-point-density data product
delivered by the system, without increasing the complexity of system control.
nn Fixed settings on all lines with fixed flying altitude for
all lines
nn Variable settings for each line with fixed flying altitude
for all lines
nn Variable settings for each line with different flying
altitudes for each line
his third optimization mode can cut the number of flight
T
lines by 40 % in large-relief terrain.
Leica MissionPro and Leica FlightPro – fully connected to
ensure proper mission execution
Leica MissionPro software works hand-in-hand with
Leica FlightPro flight management software, by transferring the entire mission plan, both sensor settings and
flight navigation information, from planner to system in
a single digital file. Direct transfer of the mission plan
minimizes the chance for operator error, and ensures
that the mission is flown exactly as intended.
Leica FlightPro provides an information-rich user interface
for both operator and pilot, allowing both crew members
access to critical data on flight navigation, progress and
system performance. The optional “remote control”
software module allows the operator and pilot to view
different presentations simultaneously to maximize
productivity.

Leica LS80-LP Scanner
Quick, comprehensive post processing
Post-flight data processing uses NovAtel Inertial Explorer
for GNSS/IMU data reduction and Leica CloudPro for
generation of the point cloud. NovAtel Inertial Explorer
utilizes “tightly-coupled” GNSS/IMU data processing to
allow full trajectory accuracy, even when satellites are
temporarily obscured, reducing the need for inefficient
and lengthy low-bank-angle turns from one flight line to
the next.
Leica CloudPro provides multi-threaded processing for
reduced processing time and a command-line interface
compatible with GeoCue job management software or
your custom workflows. And the included Leica AHAB LSS
Viewer allow simple, fast viewing and measurements to
be made in the produced data set.
Leica ALS80-CM and Leica ALS80-HP systems achieve
industry-leading measurements rates of 1.0 MHz,
reducing on-line flying time by up to 50 % over the
previous generation of systems. Leica ALS80-HA offers
an extended flying height with scan rates appropriate for
wide-area data acquisition.
Leica ALS80 accommodates operation with up to 6PiA
operation (5PiA for Leica ALS80-CM), carrying high pulse
rates to even greater flying heights.
