Online 1:24,000 scale GeoPDF Topographic Image Maps

These 1:24,000 scale topographic image maps, in GeoPDF format, are considered a beta version. The final version of these image maps for Nevada are scheduled for release in 2012. The image base of these maps is the Nevada National Agricultural Image Program (NAIP) photography flown in 2006. These preliminary versions do not include contours, hydrographic features, or Township/Range lines. They do include layers for roads, names, and a UTM NAD 83 grid. The GeoPDF format is an extension to the Adobe PDF file format enabling GIS functionality and layering within standard PDF files. These maps currently exist only over BLM lands. Those quads that are over or cut by U.S. Forest Service, Department of Defense (Nellis Air Force Range), or Department of Energy lands are generally not covered.

These maps and search engine are made available to the public through the Keck Earth Sciences & Mining Research Information Center Web Site, Library, University of Nevada Reno and the Nevada State Mapping Advisory Committee.
