Namespace:  AGI.Foundation.Terrain
Assembly:  AGI.Foundation.TerrainReaders (in AGI.Foundation.TerrainReaders.dll) Version: 19.2.399.0 (19.2.399.0)
Syntax
public override double GetHeight(
	double longitude,
	double latitude
)

Parameters

longitude
Type: SystemDouble
The longitude, in radians. Requesting a height for a longitude less than -PI or greater than PI will always return NaN.
latitude
Type: SystemDouble
The latitude, in radians. Requesting a height for a latitude less than -PI/2 or greater than PI/2 will always return NaN.

Return Value

Type: Double
The height, in meters, or NaN if the height is not available at the requested longitude and latitude.
Remarks

If HeightReference is ReferenceSurface, the returned height is relative to the surface specified by the ReferenceSurface property. If HeightReference is Shape, the returned height is relative to the ellipsoid specified by the Shape property. This method may return NaN if the requested longitude and latitude are outside the terrain region or if the terrain data indicates that the height is unknown.

It is safe to call this method from multiple threads simultaneously.
