CNRA/Digital Atlas Map Server

This page contains a near real-time listing of our map services plus helpful web links. To view the map services use products such as ArcGIS Explorer, ArcMap and ArcView, Google Earth, MapInfo, World Wind, and more.

The main web links for connecting to our services are as follows:

Pre-built Map Documents

last updated: November 1, 2009

The following are links to pre-built map documents that you can open in ArcGIS Explorer, ArcMap, and Google. This is provided so you can get a head start using our services. If you do not have one of these software products, then go to to our map portal to view links to maps that open in web browsers. These maps use many of the services shown below. ArcGIS Explorer and Google Earth can both be downloaded for free.

  • ArcGIS Explorer Document

    If clicking on the link below does not automatically open ArcGIS Explorer, then right click on the link and choose "Save as," then save the file with the extension ".nmf". Then open this file in ArcExplorer. Note: This document was created with version 9 of ArcGIS Explorer (updated: November 16, 2009).

  • ArcMap Document

    Click a map document to open it in ArcMap. If you are using ArcGIS 9.2 SP4 or an earlier version, right-click the link and choose 'Save target as...' to save the map as a local file, then open that file in ArcMap  (updated: November 19, 2009).

  • HazardMaps_09_01_2009_Seismic

    Capabilities: Map,Query,Data

    Description: The Alquist-Priolo Earthquake Fault Zoning Act was signed into California law on December 22, 1972 to mitigate the hazard of surface faulting to structures for human occupancy. It directs the State of California Division of Mines and Geology (now known as the California Geological Survey) to compile detailed maps of the surface traces of known active faults. These maps include both the best known location where faults cut the surface and a buffer zone around the known trace(s). Earthquakes happen when two blocks of the Earth's crust move relative to one another. The place where the blocks meet is called a fault, and faults tend to show up as relatively straight lines on maps. Any structure built directly on top of the fault will be torn in two when the blocks move. It's not easy to build a building that can withstand this sort of movement (often several feet in a matter of seconds), so it's best to avoid building directly on top of an active fault. (See: Wikipedia http://en.wikipedia.org/wiki/Alquist_Priolo_Special_Studies_Zone_Act). IMPORTANT!: The liquefaction and earthquake induced land slide data used for this map service are NOT statewide and are limited to select locations in the San Francisco Bay Area and Southern California.
