Parameters

data: Type: TData
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.
