Individual, tiled, Digital Elevation Models (DEM) will not be offered through the new Tiled Data Delivery System (TDDS). The current official National Map elevation data, National Elevation Dataset (NED), incorporates the DEMs and offers the best available elevation product through Seamless Data Distribution System (SDDS). The DEMs will still be available for purchase through EarthExplorer.
