Satellite-Derived Bathymetry (SDB) for the Turks and Caicos shallow water areas (MSP)

Satellite-Derived Bathymetry (SDB) is a technique that allows to create nautical charts and bathymetric maps of shallow waters and coastal regions using satellite imagery. SDB for Turks and Caicos Island was created in 2020 from a mosaic of sentinel images with the resolution of 10 m.

Lineage The SDB relates the surface reflectance of shallow coastal waters to the depth of the water column. The SDB for Turks and Caicos Islands was created from sentinel images with the resolution of 10 m. The satelite images were preprocessed with atmospheric correction and cloud masking and the mosaic of cloud-free images was created. A physics-based radiative transfer algorithm, which incorporates satellite observed surface reflectance and properties of the water column, was used to produce our bathymetry products. The control points used by the algorythm was derived from Turks and Caicos nautical chart. The process was done in the ESA SNAP software.
