The characteristics of coastal areas are dependent on their bathymetry. Variations in the sea floor can be caused by various processes, like sedimentation, and depicted by colour or contour lines representing isobaths 

Earth observation offers high spatial resolution, multi-spectral bands and open data access, enhancing the ability to monitor and manage coastal areas. Satellite images are therefore one of the reliable alternatives to assess water depth due to their wide area coverage, repeatability and low cost. 

Sentinel-2 is a wide-swath, high-resolution and multi-spectral imaging mission, also supporting water cover monitoring. The acquired data, mission coverage and high revisit frequency provide particularly effective information for Satellite Derived Bathymetry (SDB) application.

In this webinar we will focus on SDB using the ratio transform algorithm developed by Stumpf et al. (2003), using Sentinel-2 imagery for depth derivation and the retrieval of regression parameters. We will also show you how to access the RUS Service in order to download, process, analyse and visualize the free data acquired by the Copernicus satellites.

You can replay this webinar through our RUS Copernicus Training channel available on Youtube.

You can also retrieve the corresponding training support in the Train with RUS section of the RUS portal.
