TopoZone is a website operated by Locality LLC that offers free online topographic maps.


It was founded in November 1999 by Ed McNierney whose company Maps a la carte, Inc. operated out of North Chelmsford, Massachusetts. Prior to founding the company, McNierney, an organic chemistry graduate of Dartmouth College, was chief technology officer for Eastman Software, a division of Eastman Kodak. [1]

In 2003 the company partnered with the National Map making its 20-Terabyte library of digital topographic maps and aerial photography available to the USGS. The 2003 press release of the partnership said that 300 million maps had been served from 1999 to 2003. [2]

TopoZone was one of the first topographic mapping site on the web, providing visitors with free viewing and printing of the full set of United States Geological Survey topographic maps covering the entire United States. The maps are produced by the USGS, which encourages the distribution of their maps through business partners. TopoZone offered aerial photographs from the USGS and street maps from the United States Census Bureau. In 2007 complete coverage of Canada was added, using the topographic map series produced by Natural Resources Canada.

In 2007 McNierney sold the company to Demand Media and stayed on as chief mapmaker until the company was taken over by [3]

On April 9, 2008, Topozone was incorporated into Demand Media's Hillclimb Media subsidiary Links to individual TopoZone maps now forward to, with maps limited to small size and strongly watermarked. An annual $50 subscription is required to access larger maps without watermarks.

Demand Media discontinued the site in 2014 and it was eventually acquired by Locality LLC and relaunched in December 2015.

Topographic map Medium to large scale map that shows a precise map of the terrain

Topography concerns the shape and character of the Earth's surface, and maps were among the first artifacts to record these observations. In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system.
