Io: Geologic Map Index

Steven Dutch, Professor Emeritus, Natural and Applied Sciences, Universityof Wisconsin - Green Bay


There are as yet no detailed topographic or gravity data for Io. The geologic map is actually a color, albedo and geomorphology map. Since there are only two maps of Io for each region, they are presented on the same page rather than via menu like most other planetary bodies.

Hemispheric Maps

Hemispheric maps are Azimuthal Equal Area Projection, which provides a realistic impression of foreshortening at the edges without the extreme foreshortening of a true orthogonal view.

Io Hemispheres: 0 and 180.htm
Io Hemispheres: 90E and 90W.htm
Io Hemispheres: North and South Poles.htm

Large Scale Maps (5 km/pixel)

Regional maps are Azimuthal Equal Area Projection and actually extend 150 degrees from the center horizontally, so they cover more than a hemisphere.
