Description

The USGS Elevation Availability service from The National Map (TNM) shows the best available resolution of downloadable elevation data, and is updated approximately every two weeks with National Elevation Dataset (NED) releases. NED 2- (in Alaska only), 1-, and 1/3-arc-second data are staged for download by 1x1 degree tiles in ArcGrid, GridFloat, or IMG formats in The National Map viewer, while NED 1/9 arc-second data is staged by 15x15 minute tiles in IMG format only. For additional information on the NED, go to http://ned.usgs.gov/.
