	TerrainPosts data,
	double longitude,
	double latitude
)

Public Overrides Function InterpolateFirstPartials ( 
	data As TerrainPosts,
	longitude As Double,
	latitude As Double
) As FirstPartialsOfHeight

	double longitude, 
	double latitude
) override

abstract InterpolateFirstPartials : 
        data : TerrainPosts * 
        longitude : float * 
        latitude : float -> FirstPartialsOfHeight 
override InterpolateFirstPartials : 
        data : TerrainPosts * 
        longitude : float * 
        latitude : float -> FirstPartialsOfHeight

Parameters

data: Type: AGI.Foundation.TerrainTerrainPosts
The terrain data to use when evaluating the height.
longitude: Type: SystemDouble
The longitude, in native units.
latitude: Type: SystemDouble
The latitude, in native units.

Return Value

Type: FirstPartialsOfHeight
The first order partial derivatives, in native units.

Exceptions

Exception	Condition
ArgumentNullException	Thrown when data is .

Remarks

Note that the interpolation scheme may permit discontinuities along the boundaries of each terrain cell.
