This CD contains three directories (folders): rel_db, gis_db, and viewer. 

rel_db directory
----------------
     The rel_db directory contains a relational database that includes sample site data, and mine-related site inventory data compiled for the study.  Included are: 1) a README.txt file that provides a more detailed description of the contents of the directory, 2) a bitmap image (relationship_diagram.bmp) which is a diagram of all the tables in the relational database, and the relationships among them, and 3) three sub-directories (mdb, ascii, and meta).  The mdb sub-directory contains the Microsoft Access version of the relational database (BoulderAMLI.mdb); the ascii sub-directory contains relational database tables in the form of flat, ASCII files; and the meta sub-directory contains metadata (descriptive information) for the relational database.

gis_db directory
----------------
     The gis_db directory contains three sub-directories (basecart, sitedata, and geosci) that contain different types of data in formats suitable for use in Geographic Information Systems. 

     The basecart sub-directory contains base cartographic data used as geographic references for the other data.  Basecart also contains a README.txt file that provides a more detailed description of the base cartographic data.  Within this sub-directory are five more sub-directories (e00, shape, elev, meta, and drg). The e00 sub-directory contains ArcInfo export files of base cartographic coverages. The shape sub-directory contains ESRI shapefiles and .dbf files of the data contained in the ArcInfo coverages.  The elev sub-directory contains a compressed tar file archive of an ArcInfo workspace containing an elevation grid, and slope, aspect and shaded relief grids derived from the elevation grid.   The elev sub-directory also includes GeoTIFF image file representations of the elevation data, and TIFF images of legends for the elevation data image files.  The meta sub-directory contains metadata for the data in the e00, shape, and elev sub-directories.  The drg sub-directory contains U.S. Geological Survey Digital Raster Graphic (DRG) image files for the eight 7.5-minute quadrangles that contain most of the data in the Boulder River watershed study.

     The second sub-directory under the gis_db directory, the sitedata sub-directory, contains the sample site and mine-related site data from the relational database in formats compatible with Geographic Information Systems.  A README.txt file provides descriptive information about the data found in four additional sub-directories (e00, shape, dbf, and meta). The e00 sub-directory contains the site data as ArcInfo export files of coverages and ArcInfo export files of INFO files.  The shape sub-directory contains three site data layers (field sites, analysis sites, and mine-related sites) as ESRI shapefiles and .dbf files.  The dbf sub-directory contains eleven tables that contain information about the sites, and data collected at the sites.  These tables are in the form of .dbf files.  The meta sub-directory contains metadata about the data in the e00, shape, and dbf sub-directories.

     The third sub-directory under the gis_db directory, the geosci sub-directory, contains geoscientific and hydrologic data sets, as well as an ArcExplorer project file.  A README.txt file describes the contents of six geosci sub-directories: geology, geochem (geochemistry), geophys (geophysics), remosens (remote sensing), meta (metadata), and aep_project (ArcExplorer project file).  The meta sub-directory contains metadata about all of the interpretive geoscientific data.  In each of the data sub-directories, an e00 sub-directory contains data as ArcInfo export files of coverages, a shape sub-directory contains data as ESRI shapefiles, and a geotiff sub-directory contains data in the GeoTIFF format.  The pdf sub-directory under the geology directory contains the geology map in a PDF format.

viewer directory
----------------
     The /bldr_cd/viewer directory contains two data viewer software packages.  The README.txt file summarizes the directory's contents and provides instructions to install the data viewer software.  There are two sub-directories: ArcExplorer and MapSheets_Express.  The ArcExplorer sub-directory contains an executable file (ae2setup.exe) that will  install ArcExplorer 2.0 data viewer software.  Similarly, the MapSheets_Express sub-directory contains an executable file (mxsetup.exe) that will install MapSheets Express 1.3 data viewer software.
