In 2005 Niels Chr. Nielsen from University of Southern Denmark created a digital terrain model of the entire Black Sea area based on data made available by the American National Geospatial Intelligence Agency. The cell size in the model is 50 m. On the basis of this, contours with equidistance of 25 meters have been extracted.

Data sets will at some point be made available for download through our home page. Currently those interested can obtain data sets by contacting Jakob Munk Højte.
