Washington DC is a Capital in United States at latitude 38° 53′ 42″ North, longitude 77° 2′ 11″ West. Through MappingDC, local volunteers are running mapping parties, working with local governments to import data, and collaborating with local enthusiast groups to raise awareness and utilization of OpenStreetMap in and around the DC metro area.
Join us at a Mapping Party, join the mailing list, or come to one of our meetings to find out more.
Meet-ups and Mapping Parties
Two upcoming mapping parties are being discussed: Rock Creek Park and National Arboretum.
Events are being regularly organized on the mappingdc mailing list. Please subscribe and plan an event!
Mapping parties are events where anyone can come along and join in improving the free world map of everything. We show you how to collect data (survey) and get the data in to OpenStreetMap. Once you put the data in to OpenStreetMap you or anybody around the world, can use the map in interesting and creative ways.
Bring your GPS and laptop to participate fully, or borrow a GPS from us. We'll have a few to loan. It's fun. It's Free. You can help.

USGS High Resolution Orthoimagery is available as a WMS service. The imagery is ~15 cm resolution, making it more detailed than the Yahoo! imagery in Potlatch. To use the USGS WMS imagery, you can use JOSM with the WMS plugin enabled. With the imagery, it's easy to add details including individual houses (not just draw rectangles, but possible to put more detail, if you wish).
For the District of Columbia:
For Montgomery County:
For Prince George's County:
For other parts of Northern Virginia:

If you know of other public domain or license-compatible imagery sources, please add them.
Sign up to indicate which neighborhoods or areas you're interested in helping map. You can either map individually or get a group together to work in teams. Once there are about 4 or more people, then setup a time and day and meetup to map the neighborhood.
