CityTracking is a project of Stamen, a mapping and data visualization design studio from San Francisco. Stamen has been an innovator of visualizing city and public data, including its Crimespotting tool, which maps crime data in Oakland.
"To make municipal data easy to understand, CityTracking will allow users to create embeddable data visualizations that are appealing enough to spread virally and that are as easy to share as photos and videos. The dynamic interfaces will be appropriate to each data type, starting with crime and working through 311 calls for service, among others."
