| Summary: | <p>During the last years, various methods and techniques have been used to
estimate the seafloor topography with high accuracy. The topography is
considered an important component for marine applications since several
activities and infrastructures are being carried out at the bottom, column
and surface of the sea. In this, study, freely and open distributed optical
satellite images were used to obtain bathymetric data for shallow waters,
(until 30 m below sea level) based on timeseries analysis of multispectral
Sentinel-2 datasets. The ratio transform algorithm was implemented for twelve
(12) monthly images covering thus a whole year. The different generated
Digital Terrain Models (DTMs) were compared with high resolution LIDAR
measurements. The results showed that bathymetry can be obtained from
satellite data within a Root Mean Square Error (RMSE) ranging from 1.39 up to
2.56 m while more accurate results were generated during the summer period.</p> |
