compiled for geological interpretation purposes The map
of brightness, greenness, wetness, biophysical
indications and surface temperature for ecological
assessment have been compiled too.
KOSICE - biotic and abiotic components of the
environment. The same maps as mentioned above have
been prepared in Kosice district region, using SPOT pan
and Landsat TM satellite images.
The Remote Sensing Department at the Slovak
Environmental Agency is responsible of the remote
sensing and GIS implementation in the relevant
informatic and monitoring projects of the Slovak Ministry
of Environment. During the period 1994 -1995 ensured
pre-processing, georeferencing and distribution of the
SPOT panchromatic images along with the basic vector
coverage ready-to use in PC Arc View environment at all
39 districts info-workplaces over the all Slovakia as an
initial stage of RS and GIS implementation in the partial
monitoring systems Settlement, Land Use and Waste of
the future Slovak Environmental Information System.
Data from the LANDSAT TM along with the DEM were
implemented into the processing of the Territorial
Development Strategy and GIS analysis/ compositions of
the Slovak republic at the scale 1:500 O00. Remote
Sensing Department of the Slovak Environmental
Agency continues in these activities towards scales 1:25
000 up to 1:50 000 with gracious help of the Canadian
CCRS, Geomatics Int., PCI and on the contract base
with SSC Satellitbild and ArcGeo ESRI local distributor.
Activities of the Forest Research Institute in Zvolen, in
the field of remote sensing, are aimed at improvement of
collection methods and assessment of forest damage.
Satellites Landsat TM and SPOT images, aerial
photographs of various scale, videodata in visible and
infrared range and spectroradiometry are sources of
information. The aerial photographs in the aerochrome
infrared Kodak 2443 are provided by their own aeroplane
which is adapted for photoversion. The aeroplane is
being used also for aerialmonitoring on the signalised
permanent monitoring plots established in forests in the
hole territory of Slovakia in network of 16x 16 km. In
addition to these activities we cooperate in the solution of
the European n Commission Project MERA, in a part of
this Project denoted as Forest Ecosystems.
Laboratory of Al, Technical University in Kosice is
responsible of the Slovak - US Program for Science and
Technology of Geography, Kent State University, Kent,
Ohio, addresses the issue of land cover classification
accuracy in the context of data derived from fuzzy
classifiers. The project tends to determine the degree to
which spatial variations in spectral response affect the
relationship between fuzzy classifier output and subpixel
class area proportions. Information on sub-pixel class
composition is to be derived by merging remotely sensed
TM data with data collected from maps and from ground-
based surveys. The second goal is to study fuzzy pattern
recognition techniques which can be useful in remote
sensing technology.
In the Czech republic national activities in remote
sensing have been focused on varios kinds of
applications. Two nation-wide projects have been
undergoing in the country. One is the mapping CORINE
Land Cover projects accomplished under frame of the
Phare programme (GISAT company). It includes

International Archives of Photogrammetry and Remote Sensing. Vol. XXXI, Part B6. Vienna 1996
production of the digital database of land cover units
over entire country at the scale 1:100 000. The data have
been obtained by visual interpretation of Landsat TM
geocoded images followed by digitalizion. The database
will be consistent with similar products in the other
European countries. The second large project gives fast
information about crop areas to the Ministry of
Agriculture. Based on classification of the Landsat or
Spot satellite imagery the information provided contain
update agreges of the main crops on regional or district
levels. Due to cloud coverage it is not possible to get
information over hole country during one vegetation
season. Traditionally, the satelite data play important role
for monitoring conditions of the forest. Landsat TM
scenes are processed to get maps presenting the
distribution of different stage of damaged forests. The
first complete map of the forest health stage has been
prepared by Ministry of Agriculture in 1995. New
activities arre connected with usage of radar data. ERS-1
and ERS-2 data have been used for the production of
space map at the scale 1:200 000. The image maps
provide a base for geological and geomorphological
analysis of the area along the new oil pipeline
construction.
The Remote Sensing Centre at Land Survey Office in
Prague is engaged in airborne thermal infrared sensing.
The apparatus AGEMA THERMOVISION 880LWB being
at disposal is used to produce thermal maps. The
thermal scanning covers a wide range of applications for
example: At the 1994 the leakage from dam Horka,
thermal scanning of surface of the hazardous toxic waste
deposit of Spolchemie company in Chabarovice, heat
loos from roof of building in area Skoda - VW company.
The Czech Academy of Science reduced number of
institutes and specialists. Reduced Institutes are pointed
on regional projects.
