Dive into MappingDC

Welcome to the MappingDC website. Here you can learn more about mapping in the DC area, supporting OpenStreetMap, and learning more about GIS. We welcome everyone. Please contact us if you'd like to get involved.

We host periodic mapping parties. See our events page for more information. Our discussions are held on the MappingDC mailing list and we tweet @mappingdc.

To learn more about mapping and OpenStreetMap, read the Beginners Guide at LearnOSM.

DC Bike Lane Review

DDOT has given MappingDC a dump of bike lane and bike trail data. Our goal is to make sure OpenStreetMap is up to date with this information. We'll focus on bike lanes first.

There are about 1,500 bike lane features. Typically a feature is 1-2 city blocks of LINESTRING data. We're most interested in the FACILITY attribute of the features. We'll use that to map to OSM Cycleway vocabulary.

Mapping the Millennium Expansion Project at Arlington National Cemetery

In honor of Memorial Day, I thought it would be a good idea to refresh the Arlington National Cemetery. It has already been mapped very well. However the Millennium Expansion Project has been underway for some time and could be added to OpenStreetMap.

MappingDC's Bike Router

Happy Bike To Work Day!

MappingDC is please to share and updated version of the MappingDC Bike Router. Both the map data and code were updated. This map will route a bike friendly path between any 2 points in the DC area.

It uses Project OSRM for both the back end routing engine and the front end user interface. The following image shows the area covered by the router.

Let's Map Anacostia

Anacostia is booming with development. Let's capture all the new stores, restaurants, churches, studios, cleaners, banks, and schools it has to offer. After cruising along MLK Jr Ave SE and Good Hope Rd SE, we'll land at the new Anacostia Library. Here we'll save those details in OpenStreetMap.

No experience is necessary. We'll teach you how to edit the map. You may bring your own laptop or use one of ours.

For more information see the Meetup Page. RSVP not required but appreciated.

Let's Map Old Town Alexandria

Are you new to editing OpenStreetMap? This event will introduce you to surveying street level geographic features and teach you how to enter them into OpenStreetMap. It's a great event to bring your kids, young or old. It's a great event for non-technical folks who are interested in their community.
