California State Waters Map Series Data Catalog

Offshore Fort Ross Map Area

Maps that show these data are published in Open-File Report 2015–1211, "California State Waters Map Series—Offshore of Fort Ross, California."

Each GIS data file for the Offshore of Fort Ross 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 10.2.2, ESRI, 2014). Raster data layers are registered TIFF images and are in the UTM Zone 10 coordinate system. Point, line, and polygon features are in shapefile format and are projected in UTM Zone 10 coordinates. 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.

Web Services

Web services were created using an ArcGIS service definition file. The ArcGIS REST service and OGC WMS service include all the Offshore of Fort Ross data layers listed in "GIS Data Files" table. Data layers are symbolized as shown on the map sheets published in Open-File Report 2015–1211. Individual web services for each GIS file are available from the main service pages provided in the links below.

ArcMap users: Instructions to use these services in ArcMap version 10.0 or above.
