Publisher:	U.S. Geological Survey	
Title:		Spatial digital database for the geologic map of Oregon
Author:		Walker, G.W., MacLeod, N.S., Miller, R.J., Raines, G.L., and Connors, K.A.
Original NGMDB identifier: 62171


Purpose: This file set is intended to make outdated Arc/INFO e00 files available as open-format shapefiles. No modification to files has been made. Projection was not changed. 

Process: e00 files were imported to coverage, then converted to shapefile using the ArcMap commands “Import from e00 (conversion)” and “Feature Class to Shapefile” respectively. Related tables were preserved by opening in ArcMap and exporting to txt.   

E00 files convert to (description extracted from 0readme.txt):
	orgeo.e00 (principal line and polygon geologic map coverage) =
		orgeo_arc.shp
		orgeo_poly.shp
		orgeo.con.txt
		orgeo.ref.txt
		orgeo.ru.txt
		orgeo.st2.txt


Original files included:
	0readme.txt = readme
	orgeo.met = metadata file
