(**) Files in DEM-format may be read by Surfer to create a contour map, the contours of which in turn may be exported as a DXF-file (by means of the option "Map | Contour Map | Export Contours"). The DXF-file may be converted to a WAsP map file by importing – and saving as WAsP map by the Map Editor.
