Pierce County, Washington This Arcview image of Pierce County rivers and waterbodies was created with TIGER data .shp files.  Superimposed on these features is raster data of a 7.5 minute quad image of bathymetry and topography. Click here for details on how to do this.
	Tacoma, North 7.5 Minute Quad of Bathymetry & Topography This is a composite image of water depth and land height presented using .DEM files that came from NOAA and USGS, respectively. These files are in UTM NAD 1927 (Zone 10) - 30 meter resolution. Click here for details on the procedure for obtaining, converting and overlaying these files in ARCVIEW.
	Tacoma, North 7.5 Minute USGS Topographic Quad with Bathymetry superimposed The USGS Tacoma North topo quad map is superimposed on the same bathymetry with the same projection as the image above. This .DRG data can be ordered and purchased directly from USGS or can be obtained online from a DRG data exchange site that provides this data as TIF and TFW(world file) files. These 2 files are necessary to georeference this topo map image. Click here for details on where to get these files and how to do this.
	Blow-up of the Commencement Bay Area of Tacoma, WA Zoom shot of the prior image showing the location of the Dickman Mill restoration site.
	Close-up of the Dickman Mill Site with just the .DRG (.tif) USGS topo quad layer and a marker superimposed.
	Digital Ortho-photo of the Dickman Mill Site I obtained this data from http://terraserver.microsoft.com.  This is not the entire USGS digital orthophoto quad, but a cropped image meant to enhance the view of Dickman Mill.  All the images above are georeferenced, this image is not.  The georeferencing world file for this image was not available on-line, but is available from USGS for a fee.

This project was done as part of a GIS and Environmental Science TORCH (Teacher Outreach) workshop sponsored by the Woodrow Wilson Leadership Program for Teachers.  The workshop was held in Stockton, CA from 5-16 July 1999.  If you have any questions concerning this webpage contact Cheryl Greengrove at University of Washington, Tacoma.
