Abstract
    Low- and high-resolution digital bathymetry models are freely available as interoperable gridded data layers and data products. The higher resolution data, together with increasing data analyses tools, give new impetus to a more uniform geomorphological mapping of wider marine areas. To test approaches in sandy shelf areas, a multi-scale analysis is performed on data from the Belgian part of the North Sea using the Bathymetric Position Index (BPI). A comparative study of the calculated surface area and the perimeter (or contour) of sandbank features is illustrated using measures of accuracy, complexity or detailedness.
