AN ORTHOIMAGE MAP USING DATA OBTAINED FROM THE MARS ORBITER CAMERA OF MARS GLOBAL SURVEYOR

A basic requirement for the planning of future Mars missions are precise and high resolution maps, especially, of the landing site area. We present a new digital orthoimage map of Mars using data obtained from the Mars Orbiter Camera (MOC) of the Mars Global Surveyor (MGS). The new map covers the Mars surface from 180° E (180° W) to 360° E (0° W) and from 60° South to 60° North with a resolution of 231.529 m/pixel (256 pixel/degree). The mosaic was divided into 8 parts, according to the digital size of the Mars Digital Image Mosaics (MDIM2). They are available digitally at http://solarsystem.dlr.de/PG/MOC/. In addition, we announce the release of a printed map of Coprates (MC 18) based on MGS data. For map creation, digital image processing methods have been applied. Furthermore, we developed a general processing method for creating image mosaics based on MOC data. This method can be used for creating image mosaics using CCD (Charged Coupled Device) line camera data and it is applicable also for other Mars missions, whenever a CCD line camera is employed.
