Files in this report are:

sim3443_readme.txt		This file

sim3443_sheet1.pdf (79 MB)	Map sheet

sim3443_sheet2.pdf (13 MB)	Sheet with Correlation of Map Units, List of Map Units, Figure 1, 
				and index map showing faults and folds
sim3443_pamphlet.pdf (28 MB)	Explanatory pamphlet

sim3443_metadata.xml		FGDC-CSDGM metadata for SIM3443.gdb in XML format

sim3443_metadata.txt		FGDC-CSDGM metadata for SIM3443.gdb in text format

sim3443_gdb.zip (47 MB)		Primary digital database for SIM 3443. Contains:
	SIM3443.gdb   		ESRI file geodatabase of geologic map features. If you cannot 
				use this file format, see sim3443_simple.zip or sim3443_open.zip, 
				below 
	SIM3443_map.mxd		ESRI ArcMap10.7 map composition document for map image on sheet 1. 
				Does not include some cartographic enhancements in SIM3443.pdf.
				This .mxd references rasters in sim3443_base.zip which, if these 
				rasters are to bs shown, must be downloaded separately
	SIM3443_CMU.mxd		ESRI ArcMap10.7 map composition document for Correlation of Map 
				Units diagram on sheet 2
	sim3443_pamphlet.pdf	Explanatory pamphlet
	resources/		Folder that contains:
		SIM3443.style 	ESRI style file. References special fonts included in Fonts.zip. 
				This style file is an amalgam of fill shades in wpgcmyk.style 
				and line and point symbols in FGDC_GSC_20100414.style, a partial 
				implementation of the FGDC digital geologic map symbology 
		Fonts.zip	Special fonts needed for SIM3443.style

sim3443_xmlmetadata.zip	(0.3 MB)  XML-format FGDC CSDGM metadata for constituent tables, feature 
				datasets, and feature classes within SIM3443.gdb

sim3443_analyticaldata.zip (0.2 MB)  Contains:
	BoringLavaAge.xslx	Spreadsheet file of SIM3443.gdb/GeologicMap/BoringLavaAgePoints
	Geochemistry.xslx	Spreadsheet file of SIM3443.gdb/GeologicMap/GeochemistryPoints
	LuminescenceAge.xslx	Spreadsheet file of SIM3443.gdb/GeologicMap/LuminescenceAgePoints

sim3443_open.zip (33 MB)	Open shapefile version of SIM3443.gdb. Includes shapefiles, dbf 
				files, and CSV files that transcribe all elements in SIM3443.gdb. 
				Reconstruction of a working database from these files will likely 
				require some programming 
	
sim3443_simple.zip (33 MB)	Simple shapefile version of SIM3443.gdb. Because of limitations 
				of the shapefile format, and to simplify use of the dataset, does not 
				include all elements (for example, complete map-unit descriptions, 
				associated metadata tables) of SIM3443.gdb

sim3443_sources.zip (18 MB)	Selected source materials. See pamphlet for discussion of these 
				files. Contains:
	OtherSources.gdb	Not a fully-compliant GeMS database, has limited metadata
	Tualatin.gdb		    ditto
	AllDMUs.docx		Table prescribing preliminary correlations between source-map units 
				and final map units
	Correlations.html	Table describing correlations between final map units and source-map 
				units 
	Correlations.xslx	Spread-sheet version of Correlations.html

sim3443_base.zip (810 MB)	Zipped ESRI file geodatabase SIM3443_base.zip. Contains 24-ft 
				resolution DEM, NE-illuminated hillshade of this DEM, and posterized 
				gray-scale raster images of parts of USGS 1:100,000 scale 30x60-minute 
				topographic maps Nehalem River, Vancouver, Yamhill River, and Oregon 
				City
