Welcome to the Arlington County Maps and Data web site. Compiled here are the links to data and maps of Arlington County.

New Tools:

We have replaced the software for our interactive mapping site, ACMaps, with a new application. Please see the Interactive Mapping page for more details and links to the new viewers. The new software runs in MS Silverlight for the desktop and HTML5 for mobile devices.

County Street Names

The street names used in our GIS are the most current and official listing of names and spellings. We checked the County records from 1934 (when the board approved new street names) forwards to find any changes and applied those corrections in 1999. We are very confident that our listing is correct according to the County records. The Post Office does not assign street names so they are not the authority. Also if you spot an incorrect spelling on a street sign, please report it.

Check Currency of Private Online Mapping Data

Remember when using online mapping services, companies may not have the latest street data displayed. Be careful not to mistake the copyright date for the date of currency. If doubts still persist, check Arlington’s GIS Mapping Center’s interactive mapping site which displays Arlington County’s most recent street data.
