//   2004/09/17 Peter Vanroose  made spheroid() non-virtual - it just returns a member and should not be overloaded
//   2004/09/17 Peter Vanroose  do not pass vcsl_spheroid objects; use vcsl_spheroid_sptr instead

//: Represent a location relative to the earth
// 3D coordinate system that is intended to represent a location relative to
// the earth, although its use is not restricted to earthbound coordinate
// systems. 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.
