Publisher:	U.S. Geological Survey	
Title:		Bathymetric contour maps for lakes surveyed in Iowa in 2003 [Easter Lake, Polk County]
Author:		Linhart, S.M., and Lund, K.D.
Original NGMDB identifier: 77818


Purpose: This file set is intended to make outdated Arc/INFO e00 files available as open-format shapefiles.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:
	eas_bndry.e00 = 
		eas_bndry_arc.shp
		eas_bndry_poly.shp
	eas_bth_cont.e00 =
		eas_bth_cont_arc.shp
	eas_island.e00 =
		eas_island_arc.shp
		eas_island_poly.shp
	eas_targpts.e00 =
		eas_targpts_point.shp
	eas_tinpts30.e00 =
		eas_tinpts30_point.shp


Original files included:
	eas_targpts.htm = metadata
	eas_bndry.htm = metadata
	eas_bth_cont.htm = metadata
	eas_tinpts30.htm = metadata
	eas_island.htm = metadata
