abstract GetFirstPartials : 
        longitude : float * 
        latitude : float -> FirstPartialsOfHeight

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.

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