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
