Lake Mohave Geophysical Survey 2002: GIS Data Release

Federal Geographic Data Committee (FGDC) compliant metadata is available for all the data contained in this report. 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 dataset 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 8.2 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; extensions have been excluded. All the files necessary to load a shapefile have been compressed into a single WinZip file. Therefore, these shapefiles can be downloaded directly from the CD, or by clicking on the filename in the data catalog and saving the "zipped" files to a preferred location and uncompressing them. Image and text files can be transferred in the same manner.
Sidescan-sonar mosaic images are available in both the TIFF and MrSid image format. The accompanying world file for each image is necessary to display the image in its appropriate geographic location within a GIS. It is recommended that when downloading from the data catalog below, the MrSid image be selected since it is a considerably smaller file.
Clicking on the camera icon will give a preview of the dataset. Due to the extensive coverage of the dataset, the tracklines and shotpoint dataset previews only cover a small portion of the dataset. Not every file has a graphic. In the case of the sidescan mosaics, only one preview image is supplied, as the differences in projection and/or image type are not readily visible in these small previews.
For guidance in where to obtain software capable of reading shapefiles, and uncompressing zipped files, see the System Requirements page.
