5 
were founded. The fields of interest occupied by these 
groups were: 
- Systems for Evaluation of Analytical Plotters, 
- Accuracy Tests for Analytical Plotters, 
- Automated Photogrammetric Instruments and Systems, 
- Instruments for Processing and Analysis of Remotely 
Sensed Data. 
The main interest of the Commission II during a concrete 
period can be recognized very well if the designation of 
working groups is analyzed. From 1980 - 1984 5 WG are 
the basis for the Commission work: 
- Analytical and Hybrid Instruments, 
- Automated Instruments and Systems, 
- Instruments for Analysis of Remotely Sensed Data, 
- Instruments for Preprocessing, Storage and Dissemi 
nation of Remotely Sensed Data, 
- Equipment for Processing Synthetic Aperture Radar 
Data. 
We notice that no more optical-mechanical instruments 
but Analytical Plotters and automated Systems as far as 
instrumentation for photogrammetry is concerned are in 
the field of Working Groups interest. The other itemn is 
the importance of Remote Sensing which is reflected by 
more than 50% of WG activities. This tendency is conti 
nued during the following intercongress period from 1984 
- 1988. During this time 6 WG and 1 Intercommission WG 
were acting about the following themes: 
- Analytical Instruments, 
- Photogrammetric Digital Image Processing Systems, 
- Systems for Remotely Sensed Data, 
- Systems for Reception, Recording, Preprocessing, Ar 
chiving and Dissemination of Remotely Sensed Data,
