In the fall of 2007, wildfires burned out of control in southern California. The extent of these fires encompassed large geographic areas that included a variety of landscapes from urban to wilderness. The U.S. Geological Survey National Geospatial Technical Operations Center (NGTOC) is currently (2008) developing a quadrangle-based 1:24,000-scale image map product. One of the concepts behind the image map product is to provide an updated map in electronic format to assist with emergency response. This image map is one of 55 preliminary image map quadrangles covering the areas burned by the southern California wildfires. Each map is a layered, geo-registered Portable Document Format (.pdf) file. For more information about the layered geo-registered .pdf, see the readme file. To view the areas affected and the quadrangles mapped in this preliminary project, see the map index provided with this report.

The fifty-five Open-File Report 2007 Wildfire perimeter maps of southern California produced by NGTOC-Denver are available through the USGS Store (http://store.usgs.gov/). You can access these geo.pdf quadrangle maps and then download a zip container with both the PDF and readme text file, and(or) order a Map-on-Demand plotter print by either going through the Map Locator and Downloader, browsing the Featured Products area, or by doing a search within the Store.
