Atlas Server is the foundation for building your maps and apps. Atlas makes map data accessible via a private version of Mapbox.js, the same API that powers Mapbox.com. Use its dozens of plugins to make heat maps, cluster dense data, animate markers, swipe between imagery layers, and customize everything. The API also plugs into our open source iOS and Android SDKs to power your private mobile apps. And Atlas Server ships with Turf for fast GIS analysis.
