GIS/Data Catalog

This report contains an Environmental Systems Research Institute (ESRI) ArcView 3.3 Geographic Information Systems (GIS) project file in the top-level directory. This project file, ccres.apr, does not require any extensions that are not standard to ArcView 3.3. For those users who do not have ArcView 3.2 or later, the individual GIS data files can still be viewed with a compatible GIS viewer or a free GIS viewer such as ArcExplorer available from ESRI (http://www.esri.com). Please note that there are several versions of ArcExplorer software that can be installed on Windows, UNIX or Macintosh OS 10.x operating systems.

This project file requires the directory structure used on this DVD-ROM and contains a startup script that prompts the user for the drive letter of the DVD-ROM drive. This information is needed in order to establish hotlinks found with the project file. If the ArcView project file and the underlying directories are copied to the computer's hard disk (maintaining the original directory hierarchy), then the location entered for the startup script should refer to the directory location of the ArcView project file. If for some reason the directory location is entered incorrectly, then the user can click on the pink button with the yellow DVD () to re-enter the information.

Each drill location from 2006 is hotlinked to a composite JPEG image of the acquired core. To view these images, make the drillloc_2006 theme the active theme. This should activate the hotlink tool () within the project tool bar. Click on this button and then on an individual point within the theme. The corresponding JPEG image will be opened in a separate view window so the user can pan and zoom on the image. In order for this hotlink to work, the JPEG (JFIF) Image Support extension must be loaded. This extension will be loaded by default within the project file.

Federal Geographic Data Committee (FGDC) compliant metadata are available for all the data contained in this report. Each data set has metadata available in several formats. The information contained within each file is the same, but is presented differently to help make the information more user-friendly. The text, HTML, and FAQ versions of the metadata have links to those files provided below. In addition, ArcGIS 9.1 compatible XML metadata are available for use with ArcCatalog. All metadata are stored in the directories delineating the data type. For example, the metadata for individual days of collection for the 2004 raw data reside in the data/res_data/2004/raw_res folder.

Shapefiles generally include *.shp, *.shx, and *.dbf files, at a minimum. For the sake of brevity, only the filename prefix has been included in the filename designation listed below. All the files necessary to load a shapefile have been compressed into a single WinZip file, including all forms of the metadata. Therefore, these shapefiles can be downloaded directly from the DVD or by clicking on the filename in the data catalog and saving the zipped files to a preferred location and uncompressing them.

In addition to shapefiles, this report includes a registered TIFF image depicting elevation, comma-delimited text files intended to provide additional information for the corresponding shapefiles (coreloc_2006.shp, geoprobeloc_2005.shp, and piezlocs_2005.shp), Excel spreadsheets, and PDF documents. These files and accompanying metadata are included in WinZip files and can be downloaded directly from the DVD or by clicking on the filename in the data catalog and saving the zipped files to a preferred location and uncompressing them.

The Continuous Resistivity Profiling (CRP) data are organized by the date of collection. Each line of data comprises more than one file necessary for processing or as an output from the processing. These data are available in a WinZip format with the file comprising a day of collection for each of the states of processing (e.g., raw, processed, RES2DINV format). These files can be downloaded directly from the DVD or by clicking on the filename in the data catalog and saving the zipped files to a preferred location and uncompressing them.

Clicking the camera icon will give a preview of the dataset. The state outline is used in several of these images as a backdrop to orient the viewer. No graphic is presented for the core images, comma-delimited text files, Excel spreadsheets, PDF files, or CRP data. The core images can be viewed from the sediment core-images-gallery page, the CRP data can be viewed from the CRP-profile preview pages, and versions of the comma-delimited text files, Excel files, and PDF files are available as tables within the report.

For guidance on where to obtain software capable of reading shapefiles and uncompressing zipped files, see the system requirements page.
