District of Columbia Open Data

Author: Joshua Sadvari

There is no shortage of noteworthy, thought-provoking information coming out of Washington, D.C. these days… That’s right! I’m talking about D.C.’s open geospatial data!

What’s in this collection?

Close to 750 geospatial data sets covering themes such as business and economic development, demographics, environment, land use and zoning, public safety and service, transportation, and more! Most data sets can be accessed as web services or downloaded in shapefile (.shp) format for use with a desktop GIS.

What BTAA Library submitted the collection?

University of Maryland

Interesting tidbits:

  • Need to get around town during this year’s AAG Annual Meeting (April 3-7) or UCGIS Symposium (June 10-13)? Skip the taxi, and grab a bike from one of D.C.’s many Capital Bike Share locations.
