- Description:
-
- Abstract:
-
This is the Original Product Resolution (OPR) Digital Elevation Model (DEM) as provided to the USGS. This DEM is delivered in the original resolution, with the original spatial reference. All elevation units have been converted to meters. These data may be used as the source of updates to the National Elevation Dataset (NED), which serves as the elevation layer of the National Map. These data can be used by scientists and resource managers for global change research, hydrologic modeling, resource monitoring, mapping and visualization, and many other applications.
- Purpose:
-
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.
- Supplemental_Information:
-
This is an original source resolution DEM. 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.
