The network posted the most accurate map of Mars

In the Internet laid out the most accurate to date map of Mars. To compile it, scientists used 21,000 photographs taken by the Mars Odyssey orbital probe over eight years. The map can be viewed here , and in high resolution it lies here . A brief description of the card is given in a press release on the NASA website.
For photographs, a THEMIS camera (Thermal Emission Imaging System - a camera that creates an image based on thermal radiation analysis) installed on Mars Odyssey was used. With the help of a special program of combining and processing images, specialists were able to remove distortions associated with the features of camera optics on the final map.

The spatial resolution of the map is 100 meters for the entire territory of the Red Planet. For some regions of Mars, there are maps with higher resolution, but the new map is the most detailed of the existing global Martian maps. Moreover, everyone can manually improve the map by correcting the images on the Be a Martian website.

Most recently, astronomers for the first time received a complete map of the surface of Mercury - the planet of the solar system nearest to the Sun. It was compiled using approximately a thousand photographs taken by the Messenger and Mariner 10 probes.
