Depth layer is calculated as the average of soundings in each pixel. The grid resolution is 1/16 of arcminute. All DTMs are merged into a unique file.

  • DTM of the German Bight (yearly, 1982 - 2012). Classified isosurfaces of spatiotemporally interpolated bathymetries from the years 1982 to 2012, with two parameters for the purposes of reliability: Confidence and Minimum dt. The parameter Confidence [m] indicates the reliability of the modelled bathymetry. Data were generated within the framework of the German Coastal Engineering Research Council project AufMod (¿Aufbau integrierter Modellsysteme zur Analyse der langfristigen Morphodynamik in der Deutschen Bucht¿ [¿Development of integrated model systems for the analysis of long-term morphodynamics in the German Bight¿], 01.11.2009-31.12.2012).

  • Jaehrlicher Tiefen ueber den Zeitraum 1982-2012. Klassifizierte Polygone auf Grundlage von raumzeitlichen Interpolationen auf einem Gitter mit einer raeumlichen Aufloesung von 50m. Fuer jeden Jahres-Tiefendatensatz sind 2 Parameter zur Vertrauenswuerdigkeit des interpolierten Tiefenwertes angegeben: Confidence und zeitlicher Abstand zur naechst gelegenen Messkampagne. Die Daten wurden im Rahmen des KFKI-Projekts "Aufbau von integrierten Modellsystemen zur Analyse der langfristigen Morphodynamik in der Deutschen Bucht (AufMod, Laufzeit 2009-2012)" generiert. Raeumliche Ausdehnung: Kuestenlinie bis 20m Tiefenlinie.
