Useful resources

Imagery

Fairfax County has paid for its own imagery, separate from the state-wide VBMP Orthoimagery project, and it is generally preferable because it has higher resolution. The imagery is available through the OSM Editor Layer Index, putting it automatically in iD and Rapid. You can also load the imagery layer into JOSM.

County GIS Database

The Fairfax County GIS & Mapping Services offers 120+ layers of GIS data. Be sure to read and follow OSM's Import guidelines and consult with other local mappers before putting this data into OSM. The layers of interest include some about building footprints, addresses, roadway centerlines with useful data attributes, POI layers, and much more. All of the data would require transformation or translation in QGIS or some other GIS application to be suitable for inclusion in OSM.

Some of these layers include coverage of Alexandria, Arlington, and the City of Fairfax as well.
