Description
	Abstract: This is a Map Analytical System (MAPS) type 8 cell map representing elevations from the USGS 7.5 minute quadrangle named Mt. St. Helen's NW.
	Purpose:To represent digitally arrays of elevations, at regularly spaced intervals, for a number of ground positions.

	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.
