	Description:  
		Abstract:  This metadata describes the collection of 1:24K DRGs (Digital Raster Graphics) that have been merged into 100k or 30 x 60 minute images as maintained by the Bureau of Land Management Oregon State Office.  A detailed description of USGS DRGs can be found at http://mcmcweb.er.usgs.gov/drg/drg_overview.html
		Purpose:  The DRG is used for validating digital line graphs (DLGs) 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 DRGs and DOQs for revising and collecting digital data, DRGs and DEMs for creating shaded-relief DRGs 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.
		Supplemental_Information:  This collection inlcludes; edgeadded Tiffs & Sids. (see process steps for details). Locally this data set is know as the "FireTiffs".

			Title:  USGS 7.5Minute Quad Digital Raster Graphics
			Geospatial_Data_Presentation_Form:  map
Data_Quality_Information:  
	Logical_Consistency_Report:  NA
	Completeness_Report:  This set of  DRGs covers all of Oregon & Washington.
	Positional_Accuracy:  
		Horizontal_Positional_Accuracy:  
			Horizontal_Positional_Accuracy_Report:  DRGs will retain the horizontal accuracy of the source maps. Most USGS printed maps contain the National Map Accuracy Standards (NMAS) note in the collar area (to see the collar area, refer either to the printed topographic quad or to the original USGS DRG). The NMAS states that for maps on publication scales of 1:20,000 or smaller, not more than 10 percent of the points tested shall be in error by more than 1/50 inch measured on the publication scale. Test points must be 'well-defined', that is, easily visible or recoverable on the ground. For DRGs this accuracy statement applies only to that area of the DRG that falls within the neatline of the source map (excluding inset areas). Overedge areas falling outside the transformation boundary area (the map neatline), can exhibit anomalies or discrepancies. These anomalies also will appear in the map inset areas and in the map collar. For maps without the NMAS note, the horizontal accuracy is unknown. However, the DRG will retain the accuracy of the source map.
		Vertical_Positional_Accuracy:  
			Vertical_Positional_Accuracy_Report:  The vertical positional accuracy of a DRG is referenced in the DRG collar.
