Federal Geographic Data Committee (FGDC) compliant metadata is available for all the data contained on this DVD. The text, HTML, and FAQ versions of the metadata reside in the metadata directory, under a subdirectory appropriate for the data type. The links to these files are provided below. Each data set has metadata available in several formats. The information contained within each file is the same, just presented differently to help make the information more user friendly. ArcGIS 9.0 compatible XML metadata is stored in the directory with the actual data files.
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. Georeferenced images and their supplemental files can be transferred in the same manner.
ESRI formatted grids cannot be copied directly from the DVD. To successfully copy an ESRI grid, ESRI software such as ArcView or ArcCatalog needs to be used. For that reason, grids were exported from the ESRI software into an ESRI ASCII grid format. These ASCII grids and their projection file were then WinZipped into a single file. These "zipped" files are available for download by clicking on the filename. When importing these grids, be sure to import them as floating point rather than integer grids.
Clicking the camera icon will give a preview of the data set. In most cases this image contains other information to help orient the viewer. For instance, the study area graphic also contains the state boundaries for reference. No graphic is presented for the SeaBoss images or seismic-reflection profile images as these images can be browsed from within the individual folders. Within the animation section, a preview of a snippet of each animation is available, as the complete animation is quite large. The IVS previews are merely a screenshot of what is visible in the Fledermaus file.
For guidance on where to obtain software capable of reading shapefiles and uncompressing zipped files, see the System Requirements page.
