The National Geographic Map of Mars was produced in a
collaborative effort by the Mars Global Surveyor MOLA and MOC teams for the
National Geographic Society.
It is an image of Mars that incorporates over
200 million laser altimeter measurements from MOLA and about a thousand
wide-angle images from MOC. The altimetry accentuates details on the
surface not visible in images due to the dusty atmosphere of Mars, and the
image data provides realistic color. The image projection is
Winkel-Tripel. (Image Credit: National Geographic Society, MOLA Science

Using MOLA data through October of 2000, the Science
Team has produced a
very high resolution topographic shaded relief map of Mars that can be
downloaded for general use.

The map has a resolution 0.125° (300 dots per
inch) and is shown as a mercator projection to latitude 70° north and
south. For a larger map, click on the image at left.

image from MOLA was was featured in the article "The Highs and Lows of
Mars" in the February, 2001 issue of Sky and Telescope.
Shown on the map are: the
Tharsis province including the major volcanoes, the Valles Marineris, and
the Chryse outflow regions. The Argyre impact basin can be seen at the
lower right. A labeled map can be seen below.

the MOLA Science Team has produced very high resolution topographic shade maps
of Mars. The one at left is from 0 to 360 degrees E. Others are available here.

The maps at left are global false-color topographic views of Mars at
different orientations from the Mars Orbiter Laser Altimeter (MOLA). The
maps are orthographic projections that contain over 200,000,000 points and
about 5,000,000 altimetric crossovers. The spatial resolution is about 15
kilometers at the equator and less at higher latitudes. The vertical
accuracy is less than 5 meters.
first features the Hellas impact basin (in purple, with red annulus of high
standing material). The second features the Tharsis topographic rise (in
red and white). The third figure illustrates the fascinating subtle
textures associated with resurfacing of the northern hemisphere lowlands in
the vicinity of the Utopia impact basin (at the near-center of the image in
blue). (All images credited to: MOLA Science Team)
the Press release!
The resolution of the Mars Orbiter Laser Altimeter reveals changes in the
topography that were not seen in previous images. This MOLA image shows
ridges and craters that were not visible in earlier images. These images
of new features give scientists a new look at the surface of Mars. Image
