Digital Image Models

NSSDCA holds a number of digital image models (DIMs) of the planets and satellites. All DIMs listed below are in sinusoidal equal-area projection. The media listed is the storage media at NSSDCA, but the images can be copied onto other media for distribution. Further information on these DIMs is available from the NSSDCA Master Catalog by selecting the highlighted NSSDCA ID.

The resolution is given only in degrees/pixel for the outer planet satellites because the value in meters/pixel varies with satellite size. In addition to these, there are images of Jupiter, Saturn, Uranus, and Neptune on the Voyager CD-ROMs, Volumes 1-5, 9-22.
