![]() USGS standard one-meter DEMs are produced exclusively from high resolution light detection and ranging (lidar) source data of one-meter or higher resolution. The elevations in this DEM represent the topographic bare-earth surface. Scientists and resource managers use 3DEP data for hydrologic modeling, resource monitoring, mapping and visualization, and many other applications. Lidar point cloud data is also available over many areas of the US. Raster datasets include: Digital Elevation Models (DEMs), Orthoimagery, and Land Cover. The vector datasets include: The National Hydrography Dataset(s), Watershed Boundary Dataset, Governmental Boundary Units, Transportation, Structures, Elevation Contours and Geographic Names.
