assessmen ^s are operational. For example, the hydrooptical model 
and variability analysis is verified by remote sensing. 
An integrated regional monitoring (incl. soil moisture 
measurement) has been started in the Szigetkoz area. 
^ nr ^ted vegetation-water quality investigation and mapping 
was executed using SPO1 imagery in the Kiskore reservoir area. 
I_n—goo 1 oqy, the main application issues were as follow: site 
selections, mineral and hydrocarbon explorations, lineament 
analysis and thematic mapping. A cost reduction of 50X was 
achieved in regional mapping of areas of interest using Landsat 
TM and SPOT data. 
In industry and mining several microcomputer based image 
processing systems with dedicated graphic facilities are 
available for the user community. Some of the coordinated 
applications are: a computerized inventory and image archive of 
350 industrial objects lias been established based on evaluated 
remotely sensed data. For 12 dates between 1950 and 1988, change 
analysis was executed in industrial areas measuring and mapping 
environmental changes caused by industrial, mining activities. 
To locate heat losses in buildings and energy transportation 
systems, infrared techniques are used routinely. 
For land—use studies and regional planning integrated, GIS based 
inventory and analysis systems using remotely sensed data are 
under development for decentralized administrations or local use. 
VIZITERV has elaborated an integrated information management 
system concept for regional monitoring. The interactive software 
for handling, retrieval, analysis and display of the geo- 
referenced tabular and vector/raster graphical data is completed 
and ready for analysis in F’PC environment. 
It should be mentioned, two remote sensing centers are operation— 
a 1 since 1980, namely 
a) one for the meteoro1oqica1 RS data reception/processing incl. 
weather radar service managed by the Meteorological Service and 
b) one for the acquisition, archiving, preprocessing and thematic 
analysis of high-resolution aerospace imagery operated by the 
FOMI RSC. This latter is the National Point of Contact to the 
European Space Agency's Earthnet since 1983, having a full 
membership in the European Association of Remote Sensing 
Laboratories and serves as basic RS institute for the Hungarian 
Academy of Sciences. Both centers provide a wide selection of 
remote sensing data from different sources. 
The computerized national historical aerospace RS data archive at 
the Ft»MI maintains nearly 400 000 aerial photographs, about 8oo 
satellite photographs and photoproducts as well as 120 CCTs. 
The catalogue will be accessible using the terrestrial data 
transmission network (called I 2 FH), which links about 280 
institutions in the country. 
An image storage and retrieval system called PIGALLE, which can 
be also used for user—oriented, sampled imagery archives in PPC
