INSPIRE : convergence of work carried out in Poland and
at UE level
2
Background
1. In Poland the SII act of law (Act of law on spatial information
infrastructure) is implemented
2. It results from the obligation of implementing the Directive
2007/2/EC (INSPIRE Directive)
3. The introduction of the SII Act of law enforced changes in
the earlier G&C Act of law (The Act of law on geodesy and
cartography), resulting from the necessity of amending the
regulations to make them cohesive with the stipulations of
the SII Act of law, and before that with the stipulations of the
INSPIRE Directive
4. Enactments, making up the executory provisions to the Act
of law, are introduced by the Minister of Internal Affairs and
Administration. The delegation for that activity is contained
in the stipulations of the amended G&C Act of law
3
Background
Databases, being a part of the spatial information
infrastructure, are established and maintained for the entire
country in an ICT system
Those databases comprise the following registers :

state register of basic primary geodetic networks, gravimetric, and
magnetic networks,
register of land and buildings,
register of geodetic utilities,
register of borders and surface areas of administrative units,
register of municipalities, streets and addresses,
register of real estate prices and values,
registers of topographic objects and general geographic objects,
register of detailed geodetic networks,
register of airborne and satellite imagery, as well as digital
terrain model (DTM) and orthophotomap (including
aerotriangulation).
4
Technical Standards
1.
Technical standards apply to:

2.
3.
development of databases
updating of databases
making them available
Technical standards make up the executory provisions to
the Act of law on G&C, in cosequence of the stipulations
of the SII Act of law (spatial information infrastructure)
The Technical standards comprising airborne imagery and
photogrammetric studies will replace the technical
guidelines used so far, which guidelines had been
developed by GUGiK in the 1990s, that had not been
binding, however
5
Technical Standards
1.
The enactment of The Minister of Internal Affairs and
Administration regarding airborne and satellite imagery, as
well as digital terrain model (DTM) and orthophotomap,
defines:

2.
the scope of information gathered in databases ;
organization, mode, and technical standards for the development,
updating, and making databases available .
The database of airborne imagery consists of
photogrammetric aerial photographs, taken by means of
analogue or digital cameras, having the following
parameters :

scale ≥ 1:6000 (or GSD ≤ 0.10 m);
scale ≥ 1:14000 (or GSD ≤ 0.25 m);
scale ≥ 1:26000 (or GSD ≤ 0.50 m);
6
Technical Standards
The database of digital terrain model (DTM) applies to DTMs in a few standards :
1. DTM-0,
GRID 1 m
source: LIDAR data with density of 4 p./m2 (rural areas) or 12 p./m2 (urban areas)
2. DTM-1,
GRID 5 m
source : photographs in the scale of ≥1:6 000 (or GSD ≤ 0.10 m),
or LIDAR data with density of 1 p./m2
3. DTM-2,
GRID 10 m
source : photographs in the scale of ≥1:14 000 (lub GSD ≤ 0.25 m)
4. DTM-5,
GRID 15 m
5. DTM-10,
GRID 15 m
DTM for development of topographic maps in the scales: 1:10 000, 1:25 000,
1:50 000, 1:100 000
Archival DTM:
6. DTM-50 (DTED-2)
GRID 1″ (≈30 m), source : maps in the scale of 1:50 000
7. DTM-100 (EuroDEM)
8. DTM-250
7
Technical Standards
The database for orthophotomaps comprises orthophotomaps
executed in several standards :
- developed from aerial photographs :
1. ORTO-010,
pixsel 0.10 m, source: photographs in the scale of ≥ 1:6 000 (or GSD ≤ 0.10 m),
2. ORTO-025,
3. ORTO-050,
- developed from satellite images :
4. ORTO-100,
pixsel 1 m, source : satellite images with pixel ≤ 1 m,
5. ORTO-250,
pixsel 2.5 m, source : satellite images with pixel ≤ 2.5 m,
6. ORTO-500,
pixsel 5 m, source : satellite images with pixel ≤ 5 m,
8
Technical Standards
Organization and manner of gathering of iformation
1. Databases of airborne and satellite imagery, as well as digital terrain
model and orthophotomap are kept in the state resource of geodetic and
cartographic information, at the central, provincial, and district (county)
levels.
Updating of databases
1. Updating of database of airborne imagery takes place in cycles, and
covers the entire territory of the country. New photogrammetric aerial
photographs and orthophotomaps being in compliance with the
standard ORTO-025 or ORTO-50, are developed on the basis of such
photographs every five years.
2. Updating of database of digital terrain model, in the standard (DTM)
NMT-0 is carried out in cycles and covers the entire territory of the
country every 10 years.
3. In the mode of occasional (emergency) updating, new datasets are
developed for those areas of the country, for which being up-to-date as
well as providing accurate data is still insufficient.
9
Technical Standards
Making information available for public
1.
2.
Making datasets of airborne imagery and digital terrain model, as well
as orthophotomap available is executed via the geoportal of spatial
information infrastructure.
The functions of data import and export are executed by means of
GML language, in compliance with the data exchange standards
defined in technical standards.

GUGiK : the nearest taks
Directive 2007/60/EC of the European Parliament and Council,
of 23 October 2007 on the assessment and management of
flood risks (the so-called Flood Directive)
Directive imposes the obligation of preparing :
ª flood hazard maps
ª flood risk maps
until the end of the year 2013
25
GUGiK : the nearest taks
The Head Office of Geodesy and Cartography (GUGiK),
developed an IT project:
„IT project for shielding the country against
extraordinary threats ” (ISOK)
within the framework of priority axis VII of the Operational Programme Innovative Economy.
Tasks for GUGiK:
to cover app. 60% of territory by LIDAR data and DTM
to speed up the development of Topographic Database
- TBD
(this is the subject of poster presentation „The role of geodesy in
implementation of Directive on the assessment and management of flood
risks – development of accurate DTM using Airborne Laser Scanning data”)
26
ISOK Project - assumptions
Areas potentially treatened with flooding
27
ISOK Project – Technical standards

„Colourful cloud” of laser points, after classification

2.
3.
Points located on the ground
Low vegetation
(0 – 0.40 m)
Medium vegetation (0.40 – 1.70 m)
High vegetation
(> 1.70 m)
buildings and structures
engineering structures
Surfaces under water
DTM in the GRID structure, resolution 1 m
Interest in LIDAR data is expected, particularly in areas of
towns. Scanning with higher density (12 points/m2) will be
useful for spatial models of towns (3D City Models)
31
ISOK Project – organisation
Organizing issues:
1.
2.
3.
4.
The entire study area will be divided into 6 sub-areas
dividing the work into stages
staged acceptance of products
Quality control
Selection of the independent Inspector of Control and
Supervision for:

organization the entire undertaking
quality control of the delivered products
32
ISOK Project – expectations
Conclusions:
1.
On the basis of the DTM developed, as well as other
geodetic projects, methodology will be developed for
preparation of flood hazard maps and flood risk maps
2.
The results of project will find their way to the state
geodetic resource. It is assumed that they will be
extensively used, not only for the needs of water
management
3.
Interest in LIDAR data is expected, particularly in areas of
towns. Scanning with higher density (12 points/m2) will be
useful for spatial models of towns (3D City Models)
33
INSPIRE : convergence of work carried out in Poland
and at UE level
1. Work upon regulations, which result from the
implementation of the INSPIRE directive by EU member
states, became the opportunity for modernization of
standards of products derived from processing of aerial
photographs, taking into consideration the inland demand
and new technological possibilities, especially in DTM and
digital orthophotomap
2. Work carried out in Poland is in line with the recently
started work concerning SPATIAL DATA THEMES defined
in INSPIRE Directive (Annex II and III), in particular in the
following spatial data themas:

Elevation (Annex II),
Orthoimagery (Annex II)
34
INSPIRE : convergence of work carried out in Poland
and at UE level
3.
4.
That work will be continued until mid-2012 and shall be
concluded by developing data specifications in particular
data themas
Participation of Polish experts in that work shall allow for
consolidation of country specifications with European
ones
