Cartographic Applications 
  
Suggested activities are: 
-— 
registration of stereo images to a standard grid system 
derivation of ortho photos and ortho stereo triplets by 
resampling procedures 
experimental derivation of topographic and orthophoto 
maps on scales 1:500 000 and eventually 1:250 000 
revision of topographical maps up to a scale 1:150 000. 
Applications in Geology, Forestry, and Environmental 
Sciences 
  
Suggested applications are: 
correlation of MEOSS stereo data with LANDSAT MSS, TM 
or SPOT multispectral data 
geological mapping (lithology and structures) 
studies on angular variations of radiances; discrimination 
between surface and atmospheric effects 
forest inventory 
land use inventory. 
In performing these tasks two features of the MEOSS mission 
may be of special interest: 
varying illumination (approx. 26 min. time shift per day) 
nearly 90? difference of stereoscopic viewing direction 
for observations from ascending and descending orbit segment 
at low latitudes.
