Description: The USGS 3D Elevation Program (3DEP) Index service from The National Map shows where data is available for two general categories of downloadable elevation data: (1) digital elevation model (DEM) datasets at standardized horizontal resolutions, and (2) elevation source data including that used to produce standard DEMs, and additional datasets derived from ifsar in Alaska only. Distributable DEM products include: 2 arc-second (in Alaska only); 1 arc-second; 1/3 arc-second; 1/9 arc-second; 5 meter (in Alaska only); and 1 meter. The 2-, 1-, and 1/3-arc-second products are staged for download in 1x1 degree tiles in ArcGrid, GridFloat, or IMG formats, while 1/9 arc-second products are staged in 15x15 minute tiles in IMG format only. The 5-meter products are staged for download in ArcGrid only as a single mosaicked raster to each project extent. The 1-meter products are staged in 10,000 x 10,000 meter tiles in IMG format only. Distributable elevation source data include: lidar point clouds (LPC) in LAS format for various parts of the U.S., and IfSAR-derived digital surface models (DSM) and orthorectified radar images (ORI) in TIFF format in Alaska only. In addition, both topobathymetric lidar-based DEMs and LPC data products are available for very limited river areas in the US. Integrated topobathymetric elevation models are also available for some areas of the US, which are continuous-surface raster models derived from multiple sources including topographic lidar, topobathymetric lidar, sonar data, and hydrographic surveys.
