DATA CATALOG

Each GIS data file is listed with a brief description, a link to a graphic, links to metadata files, and a link to the downloadable file. The data were compiled in ArcInfo (version 8.0.2, ESRI, 1998-2002). Raster data layers are registered TIFF images in the UTM Zone 10 coordinate system with datum NAD83. Point, line and polygon features are in shapefile format, and are in geographic units (latitude, longitude) with horizontal datum NAD83. We recommend you create a single new folder within which to unzip the files you want to use. Some .tgz files will generate sub-folders when unzipped. These folders should not be changed if you intend to use the ArcView project provided below.

The downloadable files have been compressed with the UNIX 'tar' and 'gzip' commands and can be unzipped by 'gunzip' on UNIX systems or with Winzip on Windows systems. The numbers following ".tgz" are the file size when compressed and uncompressed. The .tgz file for a TIFF image includes the image (.tif), the world registration file (.tfw), and the metadata file (.txt). The .tgz for a shape file includes a .shp, .shx, and .dbf file and the metadata .txt file.

Some virus-detection software will misinterpret the compressed format as virus-bearing. Use the override option (for example, "Stop" in McAfee VirusScan) to complete the file transfer.
