A global colour mosaic of Mars from high altitude observations

A high-altitude observation campaign with the Mars Express High Resolution Stereo Camera (HRSC) was used to construct global mosaics of Mars from images captured through each of its five different spectral filters: panchromatic (nadir), red, green, blue and infra-red.

• The mosaics are available in different versions: one equirectangular global view and five orographic faces (centered on 0°, 90°, 180°, 270°, North Pole and South Pole) providing a global view in sum.
• Each version is available as a single channel image (red, green, blue, infrared and nadir) as well as an RGB composite.
• The data are currently processed at 2 km/pixel and are available in GIS-ready Geotiff format.
