British cartographer designs Earthling-friendly map of Mars

With the help of data gathered from NASA satellites and rovers, a British cartographer has come up with an Earthling-friendly map of the Red planet.

Chris Wesson, map designer for Britain’s official mapping agency Ordnance Survey has designed the group’s first map of another planet. Wesson has used a number of the same techniques used for Earth-based mapping for representing a part of Mars in a way that can be pictured by non-scientists.

This has been done considering that governments and private companies are optimistic of sending human explorers to Mars in approaching decade or next to it, so a clear map is a must.

Cartographic interpretation of Mars’ dry, dusty, and pockmarked terrain by Wesson spans 3,672 by 2,721 kilometers at a scale of 1 to 4 million. The map has detailed an area in the northern region of the planet called Western Arabia Terra, including the landing sites of two NASA rovers. Science Alert has pointed out that NASA’s Mars Pathfinder is in northwest Ares Vallis, and Opportunity is in east of Margaritifer Terra.

Like many of the agency’s Earth-based ones, the map has used an organic color palette and traditional map features, like contours colored in brown-orange, cyan colored grid lines, and a layout using a scale and legend. The motive behind this is to make it more user-friendly as compared to the technical maps that scientists use.

In an Ordnance Survey blog post, Wesson said, “I think even though the principles are the same, the design and the aesthetics of an Earth map differ considerably from any planetary map that I’ve seen before”. He added that he loves planetary maps, finding them visually quite appealing however they do at times carry scientific and unnatural presentation.
