Abstract
Using GEOSAT GM altimetry data, shipborne gravity, land gravity and GPS/leveling data, a numerical solution for the fixed altimetry-gravimetry boundary value problem (AGBVP) II is evaluated and tested. Two types of solutions are applied — with and without smoothness conditions along the coastline. Data available in the area of Newfoundland, eastern coastal region of Canada, are used. A comparison with a standard estimation method for the efficient combination of heterogeneous data, namely multiple input, multiple output system theory (MIMOST), is carried out. Conclusions for the combination of different data types and smoothness conditions along the coastline are drawn.
