RasterTerrainProviderGetHeight Method (Double, Double)

public override double GetHeight(
	double longitude,
	double latitude
)

Public Overrides Function GetHeight ( 
	longitude As Double,
	latitude As Double
) As Double

public:
virtual double GetHeight(
	double longitude, 
	double latitude
) override

abstract GetHeight : 
        longitude : float * 
        latitude : float -> float 
override GetHeight : 
        longitude : float * 
        latitude : float -> float 

Parameters

longitude

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

latitude

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

Return Value

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.
