Description:
RAC09 is a hybrid geoid model for Corsica with a grid spacing of 1.5' in latitude and 2' in longitude. It is an adaptation of
the QGC02 model to 60 GPS/levelling points. The RAC09 model represents the height of the IGN78 reference surface above the GRS80
ellipsoid. It has been assessed by using 15 independent GPS/levelling points, showing differences with an rms of 3.4 cm.
