Allan Glen from the City and County of Denver presented on Denver's Open Data Initiative at the 2013 Regional Data Summit. Previously, Denver's GIS data was available for download but required restrictive licensing agreements. Denver has since launched an open data portal, data.denvergov.org, to make city data more freely available under a Creative Commons license. The portal has seen increasing usage, with over 14,000 visits and 105,000 page views in its first six months. Denver plans to continue expanding its open data program by adding more datasets and hiring an Open Data Architect.
