How far the derived bathymetry from the Landsat 8 data is useful for near-shore wave modeling perspective especially in those areas where the other deterministic information (sonar data, echo-sounding data etc.) regarding the bathymetry is unavailable?
Utilities of Landsat 8
TCM has been working on extracting ocean depths from satellite imagery. This method is tedious and time consuming, but very worth it. Satellite derived bathymetry will allow us to improve our near shore data, which in some cases is 100% improvement. You’ll see in the examples below our current 90m resolution bathymetry compared to 30m resolution bathymetry which was extracted from Landsat 8 Imagery.
