Description: | Abstract: The GwK (map of isopiestic lines) shows the spatial position of the water table at a certain point displayed by isopiestic lines. Due to the scale of the map not all local details e.g. cones of depression caused by water works or effects of surface water were included in the map. The analog map was digitized by the LANUV (Environmental Agency of North Rhine-Westphalia) using data from April 1988, representing the maximum water level measured until this date. Isolines were scanned from the analog maps and transformed into a shape file so far. Digitization of hydrologic information such as geological layers and faults has not been carried out yet. But an edge matching of neighboring map sheets and was done and water levels were assigned with the isolines. The Geologischer Dienst NRW (Geological Survey of North Rhine-Westphalia) revised the analog data and carried out an overlay with a terrain model in order to compensate inaccuracies. |
