Map Club, Session 04 — Vibrant Maps with Mapzen

20160712_Banner_v1

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. Mapzen leverages vector graphics and OpenGL to generate speedy, beautifully-rendered tiles, easily displayed using Leaflet.

Centered on Columbia, Tricia customized Tangram’s lighting model to produce a concentrated spotlight:

Jeremiah made use of different point light properties to generate a vivid cityscape:

Along with lighting capabilities and color customization, Tangram allows for custom GLSL. (Full overview here.) Emily used a fragment shader to animate the colors of New York City buildings and water:

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

A successful week full of beautiful and strange results. Next Tuesday, in our final summer session, we will explore different projections in the D3.js JavaScript library. See you then!
