Namespace: AGI.Foundation.Terrain
Assembly: AGI.Foundation.TerrainReaders (in AGI.Foundation.TerrainReaders.dll) Version: 25.1.421.0 (25.1.421.0)

Syntax

C++

Copy

public override SecondPartialsOfHeight GetSecondPartials(
	double longitude,
	double latitude
)

Public Overrides Function GetSecondPartials ( 
	longitude As Double,
	latitude As Double
) As SecondPartialsOfHeight

public:
virtual SecondPartialsOfHeight GetSecondPartials(
	double longitude, 
	double latitude
) override

abstract GetSecondPartials : 
        longitude : float * 
        latitude : float -> SecondPartialsOfHeight 
override GetSecondPartials : 
        longitude : float * 
        latitude : float -> SecondPartialsOfHeight

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.

Return Value

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