Derivation of the topographic potential from global DEM models
Original language description
Spherical harmonic expansion to ultra-high resolution can be used to transform globally available digital elevation models into the high frequency content of the Earth?s gravitational potential. It thereby amends satellite based gravity measurements (GRACE, GOCE) and ground observations such as height anomalies from GNSS leveling or dedicated gravity campaigns on terrain. Besides a numerically stable and efficient method for the harmonic expansion on a geocentric reference sphere, the transfer from geodetic to geographic coordinates and full data restoration to appropriate heights (3-D synthesis) has to be considered. Using a series expansion eventually transforms spherical harmonic coefficients of the topography into the topographic potential or topography-reduced gravity anomalies. The concept is discussed and results from analysis of ETOPO1 are presented.
