Description:
FOGEOID2011 is a hybrid geoid model for Faroe Islands, covering the area 61-63°N and 9-5°W, with a spatial resolution of 0.005° x 0.01°
corresponding to about 500 m. It was computed by fitting the FOGEOID2010 gravimetric model to GPS/levelling data and to the water level
measurement on Suderoy. This water level information was added due to the Suderoy distance from the other islands. The adjustment was
performed by least-squares collocation. The method, implemented in the GRAVSOFT package, acts as a trade-off between the smoothness of
the adapting surface and the exact fit of the geoid in the given GPS/levelling points. The consistency of resulting geoid model with
respect to the GPS/levelling data is of the order of 2 cm on the central islands.
