The “Mars 96” Russian satellite began its mission in the fall of 1996. This satellite carries HRSC (stereo cameras with high resolution) and WAOSS (scanner and electronic stereo-optical with obtuse angles) German cameras.
This satellite provides amending images and colored visual mosaics with fully-automatic process and uses calibrated geometrical information from WAOSS, HRSC and CCD cameras for producing amending images. Orbital information for any line is derived from the whole band of visual information (improved by photogrammetric bundle adjustment) and digital terrain models (DTM) through the Image Matching Method and interpolation techniques.
The geometric aspect of making such mosaics is controlled by the bundle block adjustment method and mosaic’s radiometry is improved in this way. Coverage areas, division lines and characteristics necessary to be known in advance are implemented automatically, and do not have mutual effect on the screen of the image processing system.
High-quality colored mosaics can produce valuable colored information using IHS color conversion and considering their high resolution. This is particularly true about colored topographic images of maps on scales 1: 500,000 to 1: 50,000, and contour lines are derived from a DTM; they are desirable products of this cartographic mission to the planet Mats.
