- Abstract:
- The study presents a semi-authomated model of bathymetry derivation from various satellite imageries (Pleiades, PlanetScope, and Sentinel 2-A) with different spatial resolutions, for two islands of the south-eastern Crete coast (Chrisi and Koufonisi). The workflow of the model is based on the empirical, band ratio approach and carried out within ESRI s ArcMap application. The highest accuracy that was achieved was an RMSE of 1.1 m for the bathymetry model from the PlanetScope image for Chrisi island. A low level of turbidity (low NDTI), high amount and reliability of depth training points, specific spectral characteristic (such as narrower bandwidths) and high spatial resolution provide a more precise bathymetry model for the studied islands.
