On February 12, 2006, User:David Benbennick uploaded locator maps for all United States counties. The maps are in subcategories of Category:Locator maps of counties of the United States by state, and are also categorized by county name.

The maps use data from nationalatlas.gov, specifically countyp020.tar.gz on the Raw Data Download page. The maps also use state outline data from statesp020.tar.gz. The Florida maps use hydrogm020.tar.gz to display Lake Okeechobee.

The maps use azimuthal equidistant projection, centered on the following points (degrees latitude, longitude):
