RasterTerrainProviderGetFirstPartials Method (Double, Double, RasterTerrainInterpolator)

Get the interpolated partial derivatives of height with respect to the specified longitude and latitude relative to the provider's Shape.

Namespace: AGI.Foundation.Terrain
Assembly: AGI.Foundation.TerrainReaders (in AGI.Foundation.TerrainReaders.dll) Version: 24.3.420.0 (24.3.420.0)

Syntax

C++

Copy

public FirstPartialsOfHeight GetFirstPartials(
	double longitude,
	double latitude,
	RasterTerrainInterpolator interpolator
)

Public Function GetFirstPartials ( 
	longitude As Double,
	latitude As Double,
	interpolator As RasterTerrainInterpolator
) As FirstPartialsOfHeight

public:
FirstPartialsOfHeight GetFirstPartials(
	double longitude, 
	double latitude, 
	RasterTerrainInterpolator^ interpolator
)

member GetFirstPartials : 
        longitude : float * 
        latitude : float * 
        interpolator : RasterTerrainInterpolator -> FirstPartialsOfHeight

Parameters

longitude: Type: SystemDouble
The longitude, in radians. Requesting derivatives for a longitude less than -π or greater than π will always return NaN.
latitude: Type: SystemDouble
The latitude, in radians. Requesting derivatives for a latitude less than -π/2 or greater than π/2 will always return NaN.
interpolator: Type: AGI.Foundation.TerrainRasterTerrainInterpolator
The interpolator to use when computing the value of the partial derivatives inside the boundary.

Return Value

Type: FirstPartialsOfHeight
The FirstPartialsOfHeight with respect to longitude and latitude, in meters of height per radian.
