This research compares two U.S. Geological Survey developed methods, the stereo photogrammetry, and the physics-based methods with the National Oceanic and Atmospheric Administration composite band-ratio methods to derive bathymetry (underwater topography) from different satellite imagery such as stereo WorldView Landsat, and Sentinel-2. The methods were applied to three different areas with different environmental, water quality and geological conditions in PR, FL and GU. The initial results were aligned to ICESat-2 ATL24 bathymetry to increase vertical accuracy. Overall, the water depth penetration depends on water quality and environmental conditions as well as the quality of the satellite imagery. The stereo photogrammetry results were the most consistent with best results for PR while the composite band-ratio delivered the most accurate results for FL and GU after lidar calibration and alignment to ICESat-2 ATL bathymetry data.
