I wanted to open a discussion on GIS beyond Earth. Here are some questions so far.
Would the term GIS be changed to something else since the term "geo" means of Earth (e.g. Lunar Information Systems or Martian Information Systems...etc)?
Are there specific software packages for handling non earth data/coordinate systems?
What are some current web map applications displaying non earth data besides Google Earth's Moon and Mars viewers (e.g. http://webgis2.wr.usgs.gov/Lunar_Global_GIS/)?
