A brief description of the computer programs used by GGU in the treatment of aeromagnetic data

Abstract

Computer programs for the treatment of aeromagnetic data have been developed parallel to GGU's acquisition and compilation of basic aeromagnetic data. The first data were collected in East Greenland in 1974 (Larsen, 1975), followed in 1975 and 1976 by the systematic regional survey of parts ofthe west coast (Thorning, 1976; this report). The first programs of the system had been designed by the end of 1974 and since then there has been a gradual increase in the number of programs as well as in their effectiveness. The programs have been developed by K. Frellesvig, E. Kirsbo and P. Rasmussen of Geokon ApS in close cooperation with H. C. Larsen and the writer from GGU, with additional support from GGU's computer group. This note gives a status of the program system at the end of 1976 and will supply an easy reference for later publications on the aeromagnetic data. In the folIowing sections a brief description will be given of the hardware available to GGU and the individual programs and their interrelationship.
