IGeographicCoordinateSystem¶

module interface IGeographicCoordinateSystem

Interface for geographic coordinate systems. A geographic coordinate system maps scene coordinates to geographic coordinates, and vice versa.

Implemented by¶

Name	Type	Description
OsgGeographicCoordinateSystem	simple module	Provides an accurate geographic coordinate system using the built-in OSG API. This is mostly useful for local 3D visualizations created with osgEarth. Scene coordiantes are in meters relative to the scene origin.
SimpleGeographicCoordinateSystem	simple module	Provides a very simple and less accurate geographic coordinate system. The Earth is modeled as a sphere so you may get inaccuracies if you compare it to other wgs84 coordinates. Scene coordinates are in meter and are relative to the scene anchor point. It doesn’t support rotation so the X axis always points east and the Y axis always points south (to have the same handedness as the scene coordinate system)!
Wgs84AnchoredGeographicCoordinateSystem	simple module	Provides an accurate geographic coordinate system: the scene coordinate frame is a local tangent plane pinned to a geographic anchor point and optionally rotated. Scene coordinates are in meters relative to that anchor.
Wgs84EcefGeographicCoordinateSystem	simple module	Provides an accurate geographic coordinate system in which the scene coordinate frame coincides with the Earth-Centered Earth-Fixed (ECEF) frame (origin at the center of the Earth, Z towards the north pole, meters), using the WGS84 ellipsoid.
