Seafloor Mapping and Benthic Habitat GIS for Southern California, Volume III

DATA CATALOG

Each GIS data file is listed with a brief description, links to figures, metadata files, and downloadable files. The data were compiled in ArcInfo (version 9.1 ESRI, 2005). Raster data layers are registered TIFF images and are in the UTM Zone 10 coordinate system with datum WGS84. Point, line and polygon features are in shapefile format, and are projected in UTM Zone 10 coordinates with horizontal datum WGS84. We recommend you create a single new folder within which to unzip the files you want to use.

The downloadable files have been compressed with the UNIX "tar" and '"zip" commands and can be unzipped by "g unzip" on UNIX systems or with Winzip on Windows systems. The numbers following ".tgz" are the file size when compressed and uncompressed. The .tgz file for a TIFF image includes the image (.tif), the world registration file (.tfw), and the metadata file (.txt). The .tgz for a shape file includes a .aux, .dbf , .shp, .shx, .sbx, and .sbn file, and the metadata .txt file as well as an .html metadata version of the .txt file.

Some virus-detection software will misinterpret the compressed format as virus-bearing. Use the override option (for example, "Stop" in McAfee VirusScan) to complete the file transfer.
