Meet-ups and Mapping Parties

See MappingDC for all upcoming and past events.

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 laptop to participate. You can also use phones or GPS units to collect data. It's fun. It's Free. You can help.

Useful Resources

Open Data DC has all kinds of GIS data available for the general public. They are licensed under CC BY 4.0.

Aerial Imagery

The most accurate aerial imagery should be DC From Above Orthoimagery. It is already included in iD.

ESRI and Mapbox both update Washington DC frequently, they could also be used to track new changes.

Local areas

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.

Note: WMATA will be putting out open data sets, beginning in August 2010 and eventually to include bus stops locations and route information. We are discussing with them the license requirements and terms of use that OpenStreetMap needs in order to be able to use their data.
