This includes both current US Topo maps computer generated every 3 years since and Historical topographic maps produced by hand until Most applications have an option for toggling on map indices showing an outline of all the maps, though you must zoom in to see the lines:.
This is the only USGS site for ordering paper maps. TopoView -- The largest selection of digital options. There are three ways to get full-scale plots of USGS topographic quadrangle maps, including both Historical Topographic maps produced and US Topo maps produced present. Download the GeoPDF map file and send it to a local printing business.
Download the GeoPDF map file and plot it on your own All topographic maps produced by the U. Geological Survey USGS are in the public domain and are not copyrighted except for the following three cases that apply only to US Topo maps produced present :Most maps in the period contain commercially licensed road data see note below.
Orthoimages in Alaska are commercially licensed. Orthoimages in Hawaii were commercially licensed Topographic maps originally published as paper documents between have been scanned and published as the USGS Historical Topographic Map Collection.
Order paper The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level. These are the same topographic maps that were published by the U. Geological Survey for decades, with nice additional features from their much-loved, but discontinued TOPO!
We have provided an easy to use application that allows you to search by address, quadrangle number, and quadrangle name. User can also pan, zoom, and identify the USGS 7.
These maps are modeled on the familiar 7. US Topo maps repackage geographic information system GIS data in traditional map form; this benefits non-specialist map users, as well as applications that need traditional maps. Limited GIS functionality, such as displaying ground coordinates, is available with all maps, and the layered construction of the PDF files allows users to turn data layers on and off.
The maps include layers not present on most traditional topographic maps, such as aerial photo and shaded relief images. Many additional feature classes have been added over the life of the project, and new and better data sources have been found for others. A challenge has been finding national datasets for all the feature types of a traditional topographic map. See this FAQ for more information about specific layers. The first 3-year production cycle for the conterminous 48 states was completed in September , and the second in September The third cycle is planned for completion in Alaska has partial coverage, which is expected to be completed in Get your topographic maps here!
The latest version of topoView includes both current and historical maps and is full of enhancements based on hundreds of your comments and suggestions.
