State of Oregon Geospatial Enterprise Office 2010-06-21 Salem, OR DAS Geospatial Enterprise Office http://gis.oregon.gov/ http://navigator.state.or.us/ArcGIS/rest/services/Basemaps/Basemap_USGSquads/ImageServer Topographic map service for the state of Oregon. This service provides a digital raster graphic (DRG) of scanned U.S. Geological Survey standard series topographic maps.A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey (USGS) topographic map. The scanned image includes all map collar information. The image inside the map neatline is georeferenced to the surface of the Earth. The DRG can be used to collect, review, and revise other digital data, especially digital line graphs (DLG). When the DRG is combined with other digital products, such as digital orthophoto quadrangles (DOQ) or digital elevation models (DEM), the resulting image provides additional visual information for the extraction and revision of base cartographic information. The USGS is producing DRG's of the 1:24,000-,1:24,000/1:25,000-, 1:63,360- (Alaska), 1:100,000 and 1:250,000-scale topographic map series.</ Provide streaming USGS topographic maps for the state of Oregon.The DRG is used for validating digital line graphs (DLG's) and for DLG data collection and revision. The DRG can help assess the completeness of digital data from other mapping agencies. It can also be used to produce "hybrid" products. These include combined DRG's and DOQ's for revising and collecting digital data, DRG's and DEM's for creating shaded-relief DRG's, and combinations of DRG, DOQ, and DLG data. Although a standard DRG is an effective mapping tool, its full potential for digital production is realized in combination with other digital data 2013-01-30 publication date Complete None planned -124.8658 -116.2806 46.4365 41.8959 None boundaries elevation ISO 19115 ReferenceFramework digital raster graphics DRGs topographic topo topos USGS U.S. Geological Society digital elevation model DEM digital terrain model contour line digital contours digital image map paper map map digital line graph U.S. Public Land Survey System hydrography transportation raster digital image elevation Oregon Acknowledgement of the U.S. Geological Survey would be appreciated on products derived from these data.
