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.
