Efficient depth monitoring in shallow seas with satellite images and a limited number of echo soundings using the Bathymetry Assessment System (BAS)

Depth maps are the basic information product for bathymetric monitoring in coastal areas. Nowadays, area covering maps are obtained from interpolation of single beam echo soundings with a transect distance of typically 200m. The Bathymetry Assessment System (BAS) constructs depth maps from microware and optical satellite images plus a limited number of echo soundings. With the BAS, the distance between transects can be increased to 600m while retaining the same overall accuracy as with the traditional method. The BAS can be applied for bathymetric monitoring of shoals in shallow seas like the Wadden Sea and in estuaries like the Western Scheldt.
