For the casual map fan, Mapzen’s new suite of animated global maps are sweet, delicious eye-candy. And for the developer or map-maker, they hint at cartographic possibilities hardly available until now.
Tangram is a map-making engine that allows users to create multi-dimensional, animated maps for free. It combines Mapzen’s new vector tile service, which chops up OpenStreetMap data into easily processed chunks, and WebGL, a fancy graphics renderer, to allow “real-time map design, display, and interactivity,” according to the Mapzen website. Peter Richardson, a Tangram developer, expands in an email:
All of these things together produce effects you'd normally only see in video games, data visualization, or VFX. The Tangram team is made up of representatives from all of these industries, and we're used to a certain level of control over graphics which hasn't been readily available in the map world, so we've been working to fix that.
Richardson stresses that these effects aren’t necessarily intended for re-use; rather, they’re meant to inspire creativity with Tangram’s unprecedented level of interactive map-making control and flexibility. Still, even if you’re not about to sign up for Mapzen’s services, the imaginative maps are still plenty of fun to play with. There’s no location-search functionality on these embedded maps, but follow there is on the main Tangram page.
