Member Enumeration Documentation

enum osgTerrain::Locator::CoordinateSystemType

CoordinateSystemType provides the classification of the type coordinate system represented.

Enumerator:

GEOCENTRIC	GEOCENTRIC coordinate systems are ones mapped to the around the ellipsoid, i.e. whole earth.
GEOGRAPHIC	GEOGRAPHIC coordinate systems are ones mapped to latitude and longitude.
PROJECTED	PROJECTED coordinate systems are ones projected to a local projected coordinate system i.e. UTMs.
