This tile of the National Elevation Dataset (NED) is 1/9 arc-second resolution. The National Elevation Dataset (NED) serves the elevation layer of The National Map, and provides basic elevation information for earth science studies and mapping applications in the United States. Scientists and resource managers use NED data for global change research, hydrologic modeling, resource monitoring, mapping and visualization, and many other applications. The NED is an elevation dataset that consists of seamless layers and a high resolution layer. Each of these layers are composed of the best available raster elevation data of the conterminous United States, Alaska, Hawaii, territorial islands, Mexico and Canada. The NED is updated continually as new data become available. All NED data are in the public domain. The NED are derived from diverse source data that are processed to a common coordinate system and unit of vertical measure. These data are distributed in geographic coordinates in units of decimal degrees, and in conformance with the North American Datum of 1983 (NAD 83). All elevation values are in meters and, over the continental United States, are referenced to the North American Vertical Datum of 1988 (NAVD 88). The vertical reference will vary in other areas. NED data are available nationally (except for Alaska) at resolutions of 1 arc-second (approx. 30 meters) and 1/3 arc-second (approx. 10 meters), and in limited areas at 1/9 arc-second (approx. 3 meters). In most of Alaska, only lower resolution source data are available. As a result, most NED data for Alaska are at 2-arc-second (approx. 60 meters) grid spacing. Part of Alaska is available at the 1- and 1/3-arc-second resolution from IFSAR collections starting in 2010. Plans are in place for collection of statewide IFSAR in Alaska through 2016.
The NED serves as the elevation layer of The National Map, and provides basic elevation information for earth science studies and mapping applications in the United States. The data are utilized by the scientific and resource management communities for global change research, hydrologic modeling, resource monitoring, mapping and visualization applications.
This tile of the National Elevation Dataset (NED) is 1/9 arc-second resolution, Image file format, and covers a one degree block. The geographic area of coverage is described below in the Bounding Coordinates. Additional information for the NED may be found on http://ned.usgs.gov/. Data may be downloaded through The National Map Viewer: http://nationalmap.gov/viewer.html. Direct links for direct access by automated services are provided in the Distribution section of this metadata.

USGS NED ned19_n42x75_w115x00_id_5areas_salmonfalls_2002 1/9 arc-second 2012 15 x 15 minute IMG. The data for the study area Salmon Falls, Idaho were processed into the NED 1/9th dataset using ESRI software. The data were imported. A grid and hillshade were created, projected into geographic coordinates and clip with a footprint shapefile. Quality inspection was done by reviewing the hillshades to detect irregularities in the data, and doing a vertical comparison between the data and the existing 1/3 NED data.
Metadata was created for display through The National Map Viewer at http://nationalmap.gov/viewer.html in XML format.
