Workspace Method InterpGriddedField2ToPosition
Description
Latitude and longitude interpolation of a GriddedField2. The default way to specify the position is by rtp_pos. The interpolation is done for the latitude and longitude in rtp_pos. The altitude in rtp_pos is completely ignored. Linear interpolation is applied. The input field (*gfield2*) is expected to have latitude and longitude as first and second dimension.
