	Data Quality Information

Logical Consistency Report: Data ordered from South to North in profiles ordered from West to East.  Overedge coverage is not provided.| 
Completeness Report: Elevation for each 30m x 30m cell within this 7.5 minute quad has been captured.  In addition, additional cells have been added in order to represent this map as a rectangle.  The elevation of these cells has been set to 0.| 

Positional Accuracy
	Horizontal Positional Accuracy
		Horizontal Positional Accuracy Report: Horizontal accuracy is dependent on horizontal spacing of the elevation matrix.  Inability to recover positions of features at less than 30m spacing results in defacto smoothing.|
	Vertical Positional Accuracy
		Vertical Positional Accuracy Report: Vertical accuracy is dependent on horizontal grid spacing, quality of source data, collection procedures and digitizing system.|

	Process Step: 
		Process Description: USGS produces a 7.5 minute DEM with a 30m sampling interval.  DEM is produced either from digitized map contour overlays or from the scanning of quad-centered photographs.
		Source Used Citation Abbreviation: USGS NMD
		Process Date:	30-Mar-78.
		Source Produced Citation Abbreviation: NA

 				Postal Code:	22092	
	Process Step: 
		Process Description:Once the DEM has been loaded by BLM the MOSS IMPORT command is run to create a type 8 cell map.  To create rectangular grid, IMPORT adds cells to the map and sets their elevation to 0.
