The project GARFIELD is a current initiative for the generation of a new high-quality gravity field solution for the Austrian region. Former solutions still show inconsistencies compared to geoid heights from GPS/leveling campaigns. With new methodical developments, these deficits should be compensated.
The final aim of GARFIELD is the generation of a highly precise gravity field for deriving
To achieve this goals, a proper combination of global and terrestrial data is sought. In tradition of former Austrian geoid solutions, the method of Least Squares Collocation (LSC) is chosen as baseline strategy. Alternatively, a Gauß-Markov model based on Radial Basis Functions will be implemented as complementary approach.
This project is funded by the Austrian Science Fund (FWF): Project number P 25222-N29.
