California State Waters Map Series Data Catalog

Drakes Bay and Vicinity Map Area

Maps that show these data are published in Open-File Report 2015-1041, "California State Waters Map Series--Drakes Bay and Vicinity, California."

Each GIS data file for the Drakes Bay and Vicinity map area is listed below with a brief description, a small image, and links to the metadata files and the downloadable data files. The data were compiled in ArcMap (version 10.2, Esri, 2014). 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 that you create a single new folder within which to unzip the files you want to use.

The downloadable data files have been compressed with the "zip" command, and they can be unzipped with Winzip (or other tool) on Windows systems. The .zip file for a TIFF image includes the image (.tif), the world registration file (.tfw), and the text (.txt) and XML (.tif.xml) versions of the metadata. The .zip for a shapefile includes the .aux, .dbf, .shp, .shx, .sbx, and .sbn files, as well as the text (.txt) and XML (.shp.xml) versions of the metadata.
