All the images in this directory (and all its subdirectories) were created from true topography data of planet Mars as published by NASA's Mars Orbiter Laser Altimeter group.

The used topography information has a horizontal resolution of either 1/64 ° (i.e. less than 1 arc minute, that is 1 square kilometer around the equator) or 1/128 ° (i.e. less than 30 arc seconds, that is 0.22 square kilometers around the equator) and a height resolution of 1 meter. It was converted (using a self-written tools) from raw MOLA data tiles covering the complete planet.

The color of the images is either synthetic (and mostly red because we all know that Mars is redish) or one of the handful visible color maps of Mars found on the internet was used. Note that these "visible" maps differ significantly in their color.

New: I decided to publish some more technical details.
