TerriaJS is a TypeScript library for building rich, web-based geospatial data explorers with 2D and 3D visualization, powered by Cesium/WebGL with a Leaflet 2D fallback. It supports large nested data catalogs, dozens of geospatial file and web service formats, time animation, region mapping, and shareable map URLs, and can be deployed as a static website.

Use cases

  • build a web-based 3D globe map viewer
  • visualize geospatial data catalogs with WMS and WFS layers
  • create a browser-based digital twin with 2D maps and 3D models
  • map CSV data onto statistical regions like LGAs or electoral districts
  • animate time-series geospatial layers over time
  • let users drag-and-drop GeoJSON, KML, or CSV files onto a map
  • share a map view as a reusable URL
  • build a public open-data spatial data platform

When to choose

  • you need a full-featured geospatial data explorer with 3D globe and 2D fallback
  • you must federate many data sources (WMS, WFS, Esri, CKAN, 3D Tiles) into one catalog
  • you want a deployable-as-static-site map application without server-side dependencies
  • you are building a spatial digital twin or government open-data map

When to avoid

  • you need a lightweight slippy map with a few markers
  • you want a mobile-native mapping app rather than a web application
  • you need heavy server-side geoprocessing rather than client-side visualization
  • your team cannot work with a large TypeScript/React library and its build tooling
