The Mars Topo Add-on for NASA World Wind is based on the high resolution
elevation data obtained from the Mars Orbiter Laser Altimeter (MOLA). This add-on was developed
before the Arizona State University MOLA Color imagery was available as online tiles. It
displays color as a function of elevation in a shaded relief map.
The Mars Topo Add-on differs somewhat in appearance from the ASU data. It employs lighter
colors and more pronounced shading than its online counterpart. These analogous layers are
compared in the figures at right.
