This is a tile of the National Elevation Dataset (NED) and is one meter resolution. Data in this layer represent a bare earth surface. The National Elevation Dataset (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. 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 non-seamless high resolution layers. Each of the seamless 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 is derived from diverse source data that are processed to a common coordinate system and unit of vertical measure. The spatial reference used for tiles of the one meter layer within the conterminous United States (CONUS) is Universal Transverse Mercator (UTM) in units of meters, and in conformance with the North American Datum of 1983 (NAD83). All bare earth elevation values are in meters and are referenced to the North American Vertical Datum of 1988 (NAVD88). Each tile is distributed in the UTM Zone in which it lies. If a tile crosses two UTM Zones, it is delivered in both zones. Only source data of one meter resolution or finer are used to produce the NED standard one meter layer
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, and many other applications.
This is a 10,000 meter by 10,000 meter tile. 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.
