Skip past contents information

Data Catalog

This report contains geographic information system (GIS) data in vector and raster formats. The vector data are available in Esri shapefile format. Shapefiles generally include .shp, .shx, and .dbf files at a minimum. All these data files include the .prj files that contain the dataset projection information. The raster data are available in Esri binary grid format and GeoTIFF format. For the sake of brevity, only the filename prefix has been included in the column ‘Filename’ listed below. 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 format. 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 in the links in the ‘Metadata’ column listed below. The data files can be downloaded directly from the ‘Download link and file size’ portion of the tables.

In addition to the GIS data, this report also contains CRP and chirp seismic-reflection data. The CRP data are 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. The seismic-reflection data are available as JPEG images of the profiles and in the SEG-Y data format. All of the JPEG images of the seismic profiles are available for download in a single compressed zip file. The SEG-Y format files are available from the link to the folder where these files reside (data/seismics/segy/) and can be downloaded individually.

The CRP tracklines as well as the seismic-reflection profile 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, and the “hlink2” attribute points to the long version of the EarthImager 2D JPEG image. Within the seismic-reflection tracklines shapefile, the attribute “hotlink” points to the JPEG image of the seismic-reflection profile. The metadata for each trackline shapefile gives further instruction on using the hyperlink feature.

Additional data included in the tables below are the HYPACK navigation files (both raw and converted to shapefile format), the YSI 600 XLM surface water data, and the handwritten data acquisition logs converted into the Portable Document Format (PDF). These files along with the FGDC-compliant metadata are available from the tables in compressed zip files.

To download the data from the table below, use the mouse to right-click on the link in the ‘Download…’ column, then select ‘Save Target As…’ to save the compressed zip file to the local hard drive. Microsoft Windows, since the Millennium Edition, 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.

Data Organization

The data are organized in folders on the website. Data layers can be downloaded individually using the table below. If the website folder structure for the data is replicated on a computer, the provided ArcMap 9.2 map document, ofr2011-1039_IndianRiverBay.mxd, can be used to display the data layers. The ArcMap document was created with the "Save As" command in ArcMap 9.3.1 in order to generate the 9.2 version document.
