Publisher:	U.S. Geological Survey	
Title:		Bathymetric contour maps for lakes surveyed in Iowa in 2003 [Don Williams Lake, Boone County]
Author:		Linhart, S.M., and Lund, K.D.
Original NGMDB identifier: 77832


Purpose: This file set is intended to make outdated Arc/INFO e00 files available as open-format shapefiles.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 geodatabase using the USGS EGIS toolbox commands “Import from e00 (conversion)”, then "ArcInfo Coverage to File GDB (conversion)". Coverages were then converted using ESRI “Feature Class to Shapefile”. Related tables were preserved by using the EGIS toolbox "Convert ArcInfo Table".

E00 files convert to:
	dw_bndry83.e00 = 
		dw_bndry83_arc.shp
		dw_bndry83_poly.shp
	dw_bth_final.e00 =
		dw_bth_final_arc.shp
	dw_targpts83.e00 =
		dw_targpts83_point.shp
	dw_tinpts83.e00 =
		dw_tinpts83_point.shp


Original files included:
	dw_targpts83.htm = metadata
	dw_bndry83.htm = metadata
	dw_bth_final.htm = metadata
	dw_tinpts83.htm = metadata
