A coordinate system based on latitude and longitude.
For a list of all members of this type, see IGeographicCoordinateSystem Members.
Some geographic coordinate systems are Lat/Lon, and some are Lon/Lat. You can find out which this is by examining the axes. You should also check the angular units, since not all geographic coordinate systems use degrees.
