Map Club spent this week’s session exploring Mapzen, an open, sustainable, and accessible mapping platform. Attendees focused specifically on Tangram, an open-source renderer that allows intricate control over the design of web-based interactive maps.

Eric imported Transit App trip requests, and used the date of a request to extrude elevation:
