MappingDC is a group organized around improving the quality of OpenStreetMap in and around Washington DC. We meet periodically for on-the-street mapping and mappy hours. See http://mappingdc.org for more information.<br>
"Thanks for coming out everybody! I had a lot of fun and hope you did too.
We added about 300 features to the map and edited a lot more with more details and information, and had up to 15 people editing the map!..."
