Available Digital Data and Metadata

The following table lists the digital data available on this CD-ROM.  These data are listed by chapters.  Metadata for the individual data layers may be accessed by selecting the Layer Name.  The ArcView shapefiles are available as individual component files or a zip file containing the listed files.  If the individual files are selected for download, the user must select, at minimum, the 'dbf', 'shp' and 'shx' files.  All downloaded files must be saved to the same directory.
