e the criticism of space agencies designing
platforms - sensors and uses according to the top
down principle, while a user oriented bottom-up
strategy was needed.
It is noteworthy that the first international presenta-
tion of the USSR space efforts with cameras such
as the MKF 6, the KATE and the KFA 1000 cameras
took place during the Commission Ill Symposium in
Leipzig in 1986. This really opened up international
discussions.
At the Washington ISPRS Congress of 1992 a new
situation had arisen. The US Landsat Commercial-
ization Act had taken its full effect, and hopes for
international cooperation
in the provision of high
resolution satellite data
for a price everyone could
made in automated digital data extraction for stereo
image matching to derive digital elevation data, in
classification and object retrieval of multispectral,
multitemporal and multisensoral data after geo-
coding, and in generating elevation data from
interferometric radar signals.
3. SUMMARY OF CURRENT SATELLITE SYSTEMS
AVAILABLE FOR USE IN MAPPING
The currently available satellite data systems useful
for mapping are summarized in tables 1 and 2.

e 2 sessions at the Commission IV Symposium,
Athens, Georgia, June 1994
e Workshop and Conference, Anna University,

Proceedings of the 1993 Workshop and the 1994
Symposium were published. They are in preparation
for the 1995 Workshop.
In these proceedings the rapid progress has been
documented. The progress is not only in the
provision of satellite imagery by stereo systems, by
multispectral systems, by coherent radar systems,
but perhaps, even more significantly, by progress
