) As Double

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

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

Parameters

longitude

Type: SystemDouble
The longitude, in the native units of the terrain provider.

latitude

Type: SystemDouble
The latitude, in the native units of the terrain provider.

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.
