Library for building catalog-driven 2D and 3D web geospatial explorers.

TerriaJS is a TypeScript/JavaScript library for building rich, web-based geospatial data explorers. It combines catalog-driven layer management with Cesium-powered 3D globes and a Leaflet-based 2D fallback, while connecting to many file and web-service sources. The library can be bundled into a static site, and the Terria platform also offers a hosted deployment.
