BATHYMETRIC MODEL OF BACURANAO BEACH OBTAINED FROM BATHYMETRY DERIVED FROM SATELLITES.

Abstract

In the last ten years, the use of Satellite-Derived Bathymetry (BDS) has been promoted, yielding satisfactory results in terms of economic impact, on the basis that it allows considerable savings in human and financial resources. However, there are several limitations in Cuba, which make it impossible for this method to be used in the production of nautical charts.
In this work, the authors address the importance of the use of this method in bathymetric surveys in shallow waters for cartographic purposes, or to be used as alternative tools that allow hydrographers to have preliminary information about a study area. The aim of its preparation is to present the work carried out to obtain a bathymetric model of Bacuranao beach, based on the use of Bathymetry Derived from Satellites. To this end, a 10 m Sentinel-2 satellite image, with spatial resolution, was used and its processing was carried out with the SNAP program. The mathematical model used for the determination of the depths was the one developed by Stumpf. The accuracy obtained in the determination of depths is +/- 40.3 cm, a value that is within the permissible range according to the technical standards for bathymetric surveys of Order 1a) according to the International Hydrographic Organization (IHO).
