In merging surface gravity data with airborne- and satellite-gravity data, a problem of inconsistency at long- and medium-wavelengths occurs. To deal with this problem, a draping technique can be used, which is an empirical technique by which the consistency is imposed upon airborne- and satellite-gravity data by appropriate corrections. The present paper describes some of the techniques used in a recent attempt to merge gravity data over parts of Greenland and the surrounding waters (59°-76°N, 15°-72°W). The least squares collocation draping techniques were implemented in the GRAVSOFT software system.
