NASA DEM is a global 30m resolution digital elevation model (DEM) optimized by reprocessing STRM data and combining it with other elevation datasets such as ASTER GDEM, ICESat GLAS and PRISM. By processing SRTM data and integrating it with other data sets, the accuracy of elevation data on a global scale, especially in complex terrain areas, has been significantly improved. </p>",
