Interactive image map of the global topography of Mars. Hover your mouse over the image to see the names of over 60 prominent geographic features, and click to link to them. Coloring of the base map indicates relative elevations , based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor .
The Mare Boreum quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Mare Boreum quadrangle is also referred to as MC-1 (Mars Chart-1). [1] Its name derives from an older name for a feature that is now called Planum Boreum, a large plain surrounding the ...
On Earth, the zero elevation datum is based on sea level (the geoid). Since Mars has no oceans and hence no 'sea level', it is convenient to define an arbitrary zero-elevation level or "vertical datum" for mapping the surface, called areoid. [9] The datum for Mars was defined initially in terms of a constant atmospheric pressure.

Some of the low elevation outflow channels extend into Hellas from the volcanic Hadriacus Mons complex to the northeast, two of which Mars Orbiter Camera images show contain gullies: Dao Vallis and Reull Vallis. These gullies are also low enough for liquid water to be transient around Martian noon, if the temperature were to rise above 0 Celsius.
The maps below were produced by the Mars Global Surveyor ' s Mars Orbiter Laser Altimeter; redder colors indicate higher elevations.The maps of the equatorial quadrangles use a Mercator projection, while those of the mid-latitude quadrangles use a Lambert conformal conic projection, and the maps of the polar quadrangles use a polar stereographic projection.
Listed are the elevations of the peaks (the vertical position relative to the areoid, which is the Martian vertical datum — the surface defined as zero elevation by average martian atmospheric pressure and planet radius), which is not the height above the surrounding terrain (topographic prominence). Listed mons elevation is the highest point ...
