Image Processing
The base images consist of a merged data-set from two different instruments. The Mars Express High-Resolution Stereo Camera Mars Chart (HMC30) data are used as reference data-sets providing the geodetically controlled topography base and the seamless base imagery covering the complete region. In addition, 33 single images of the Mars Reconnaissance Orbiter Context Camera with a resolution of up to 5 m were used.
The single CTX images have been radiometrically normalised using the HRSC MC13 tile as brightness reference. The two data-sets have been colorised by the HRSC color channels using pan-sharpening techniques.This mosaic image is then combined with topography information from the digital terrain model (DTM) to generate a three-dimensional landscape.
Finally, for every second of the movie 50 separate frames are rendered following a pre-defined camera path in the scene. The vertical exaggeration used for the animation is 3-fold. Atmospheric effects, i. e. clouds and haze have been added to conceal the limits of the terrain model. The haze starts building up at 200 km distance.
