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.
