Federal Environment Agency (FEA)
1 Programs
During the period 1992-1996, the FEA realized the
following projects with respect to the topics of
ISPRS:
= CORINE-Landcover (Com. VII)
— March (river) water meadows (Com. VII)
Other projects referring to water quality, soil
contamination by radioactivity, dangers caused by
waste deposits and other environmental inquiries
were carried out by means of geographical
information systems. They will not be explained in
more detail.
2 Descriptions
2.1 CORINE (= Coordinated Information on the
Environment)
This is a project dealing with "the compilation, co-
ordination and adjustment of information about the
situation of the environment and the natural
resources in the European Community (EC)' by
means of a geographical information system. The
program comprises all members of the EC and is
the basis for a future European environmental
information system. It will be realized in a European
environmental agency, its goal being to support the
respective activities of the Community. One of the
tasks is the land-cover project, which will be
performed by means of Landsat-TM (channels 4,5,
3)-images. The classification distinguishes 44
classes regarding areas > 500 m x 500 m. The
results will be integrated in a database with a period
of renewal every ten years.
2.2 March river
The very delicate areas of water meadows in the
March-Thaya region are monitored periodically by
means of infrared colour flights (Federal Office of
Surveying). From these images the state of the
biotops is classified in a very detailed manner and
the results are inserted into a GIS of the FEA. The
diagnosis from the images is completed by
terrestrial investigations. The whole work is
dedicated to the preservation of the March-Thaya
water meadows.
Federal Center of Research and Standardization
"Arsenal"
This institute works in the fields of hydrogeology,
applied geophysics and geotechniques (waste
deposits) by means of the GIS/ARC/INFO in order
to provide administrative authorities with all
informations required for | decision-making
processes. Apart from these projects the Arsenal
participates in a new remote sensing project called

International Archives of Photogrammetry and Remote Sensing. Vol. XXXI, Part B6. Vienna 1996
"MOMS-MISSION", which is aimed at mapping
neotectonique zones of intrusion. The test area will
be a special region of Lower Austria where remote
sensing data will be compared with terrestrial
explorations. As a subproject, a remote sensing
infrastructure is installed at the institute. These
activities belong entirely to Com. VII.
Federal Forest Research Office
The activities of this institution may be summarized
unter the topics of Com. I, Com. IV and Com. VII.
Because of insufficient ground resolution, space-
borne remote sensing data cannot be used for its
purposes. Hence, the investigation is entirely based
on infrared aerial images taken periodically of
selected forest areas during the growth period in
order to get. information about damage by
immission. The scale of images is about 1:7,500.
The models are triangulated, coordinates and
parameters of orientation are stored, and the
interpretation referring to the biological state of
single trees, their topographic surrounding (ex-
position, inclination of terrain, elevation etc.) and
other indicators are transmitted from the analytical
Stereoplotter (Zeiss Planicomp P1) to an
information system. This approach offers various
possibilities of visualization and mapping. The
system is in operation since 1992 and provides
continuously annual informations about Austrian
forests.
B. FEDERAL PROVINCES
Photogrammetry and remote sensing are used in a
very typical way by the administrations of the
Austrian federal provinces. As the responsibilities of
those administrations cover all kinds of planning,
the applications refer to the production of basic
maps for several purposes and - because of the
mountainous surface - to DTM production. The
most important fields are:
— Environmental planning by means of maps at
scales ranging from 1:5,000 to 1:10,000
depending on the economic significance of the
regions in question. They are prepared in the
traditional way of graphical maps or by means of
orthophotos.
— Road planning using scales of 1:10,000 and
larger. The applications cover detailed technical
drafts (1:1,000 or 1:2,000), checking of variants,
general studies and, last but not least, maps on
noise pollution.
— Forestry planning and inspection by means of
infrared aerial photos.
— Land use classification based on Landsat and
Spot multispectral images.
In general, traditional photogrammetric evaluation is
performed by private photogrammetric enterprises.
Special applications, for example satellite remote
sensing or infrared image interpretation, are carried
