A specialized hydrographic dataset derived from 90m DEMs that maps global river networks, basins, and streamflow with high precision. Key Technical Specifications
These models typically cover Earth's landmasses from pole to pole (TanDEM-X) or between 60°N and 56°S latitudes (SRTM).
This is a widely used, "void-filled" version of the original NASA data. It has been processed to remove gaps caused by radar shadows or water bodies, making it more reliable for hydrological and topographical analysis.
