This report contains Geographic Information System (GIS) data in vector format. The vector data are available in Esri shapefile format. Shapefiles generally include .shp, .shx, and .dbf files at a minimum. All the data files include the .prj files, which contain the dataset projection information. For the sake of brevity, only the filename prefix has been included in the column 'Filename' listed below; extensions have been excluded. Clicking on the image in the 'View' column of GIS-compatible data will display a thumbnail image of the dataset. The files necessary to load each dataset into a compatible GIS have been compressed into a single zip file, along with Federal Geographic Data Committee (FGDC)-compliant metadata in text, FAQ, HTML and XML formats. A second XML metadata format generated and viewable by ArcCatalog is also included in the compressed zip file. In addition, the FGDC-compliant text, FAQ, and HTML versions of the metadata for each dataset have links provided below. The data files can be downloaded directly from the tables below.

In addition to the GIS data, this report also contains CRP data available in both raw and processed formats. Each line of data acquisition comprises multiple files as described in the Methods section of this report. For this reason, these data are organized by day of collection and are available as compressed zip files for each day of data collection. These download files also contain the FGDC-compliant metadata in text, FAQ, HTML and XML formats.

The CRP tracklines can be hyperlinked to associated images within ArcGIS. Within the CRP tracklines shapefile, two text attributes, "hotlink" and "hlink2", can be utilized to hyperlink to the JPEG images of the resistivity profiles. The "hotlink" attribute points to the MATLAB JPEG image, while the "hlink2" attribute points to the long version of the EarthImager 2D JPEG image. The metadata for the trackline file (resgpslns_gsbay) gives further instruction on using the hyperlink feature.

The handwritten data acquisition logs maintained during the survey were scanned and converted into the Portable Document Format (PDF). This file along with the FGDC-compliant metadata is available in a compressed zip file available from the table.

To download the data from the table below, right mouse click on the link in the 'Download' column. Select 'Save Target As...' to save a compressed zip file to the local hard drive. The download file size is indicated under the file name. Microsoft Windows Millennium Edition and later supports extracting zip files natively without additional third party software. Simply double-click on the file to begin the extraction wizard. In cases where a utility program to uncompress files is needed and not currently installed on the local system, 7-zip (http://www.7-zip.org/) provides an open source utility. These files were compressed with WinZip version 9.0.
