Moroccan geoid determination from spatial gravity using recent GGM

geoid determination in Morocco suffers from lack of terrestrial gravity data. Besides available data are heterogenous. Spatial gravity development, with Spatial Gravity missions like CHAMPS (2000), GRACE (2002) and GOCE (2009) participate to huge improvement of this field. Collected data is used to compute Global Geopotential Model (GGM) using only satellite data or combining it with terrestrial gravity measures. We use some available GGM to compute gravity field functionals, especially geoid and gravity anomaly over Morocco area. Using precise GPS-Leveling data from ANCFCC we compare produced grids for best use with GNSS leveling determination.
