Detailed Description
Reference sphere or ellipse for a geographic coordinate system.
The default value for a reference ellipsoid is the Clarke 1866 model, but this class contains a constructor that allows reference spheroids to be constructed with values for several different standard models. See the book "Map Projections Used by the U.S. Geological Survey" (Snyder, John P., "Map Projections Used by the U.S. Geological Survey," Geological Survey Bulletin 1532, U.S. Government Printing Office, Washington, 1982.) for further detail on most of these coordinate systems.
