This invention discloses a method for constructing a seamless land-water DEM based on multi-source satellite data fusion. The study area is divided into bare land, drawdown zone, and perennial waterlogged area based on the annual average water frequency of Sentinel-2 imagery. Using the ICESat-2 ATL08 ground point cloud during the dry season and contemporaneous Sentinel-2 imagery, the underwater topography of the drawdown zone is constructed using an XGBoost model. Using the ATL13 water surface elevation and depth during the wet season and contemporaneous Sentinel-2 imagery, the underwater topography of the perennial waterlogged area is constructed. Based on the water frequency, the results from the drawdown zone and the perennial waterlogged area are fused to generate a complete and continuous underwater topography. The elevation of the bare land ALOS DEM is then corrected using the ATL08 point cloud and fused with the topography of the drawdown zone and the perennial waterlogged area, achieving a seamless connection between land and water topography and constructing a high-precision integrated land-water DEM, thus improving the accuracy of the water area and shoreline topography.
