Bathmetry of Lake Constance – State-of-the-art in surveying a large lake

In 2014 the by far largest German lake has been newly surveyed. The transnational project is funded by the European Union and delivers a detailed 3D-model of the lakefloor. The German project name is »Tiefenschärfe – Hochauflösende Vermessung Bodensee«, which in English roughly means: high-resolution survey of Lake Constance. The German term »Tiefenschärfe« (in optics and photography: depth of field) plays with the meanings of »Tiefe« (depth) and »Schärfe« (sharpness). The result of the survey shall be a clear and sharp image of the deep and shallow lakefloor. At present the LiDAR and multibeam data are still processed, but first results are presented in this article.
