Evaluation of Methodologies for the Determination of Bathymetry Using Worldview-2 Imagery: A Case Study at Lake Pramoritsa, Greece

A basic research area in remote sensing is the depths calculation and the aquatic environment protection. This paper explores the depths measurement of the Lake Pramoritsa (North-Western Greece), through digital processing of multispectral image Worldview-2 (WV-2). To this objective, a bathymetry algorithm and different image classifications have been used. The Digital Terrain Model of the study area before the dam construction is known. The results of the bathymetric have been evaluated, demonstrating thus, that the automatic classification of the multispectral image WV-2 first four channels, allow the depths calculation with greater accuracy.
