Bathymetry analysis with use of Sentinel-2 images

Abstract

Bathymetry is described as Sea and Ocean depth measurements, and performed by many methods. Traditional methods, which are still used from the past to the present, have been replaced by modern methods with the development of technology. Sonar systems, LIDAR and remote sensing systems are listed as examples of these modern methods. The use of acoustic systems or LIDAR, are not economical in terms of both time and cost. In this study, remote sensing methods are investigated in order to minimize the time and cost. It is aimed to extract the information about bathymetry with use of free of charge satellite images. As input data, Sentinel-2 satellite images of the study area and reference bathymetry points from predefined locations, were used. Band ratio and multi-band methods are used, and the results were evaluated.
