TerriaJS is an open-source framework for web-based geospatial catalogue explorers.

It uses Cesium and Leaflet to visualise 2D and 3D geospatial data, and it supports over 50 different Web APIs, file formats and open data portals.

It is almost entirely JavaScript in the browser, meaning it can even be deployed as a static website, making it simple and cheap to host.

TerriaJS is used across the globe to create next-generation Digital Twin Platforms for open geospatial data discovery, visualisation and sharing - it is used to drive

• Digital Earth Australia Map
• Digital Earth Africa Map
• Pacific Map (Digital Earth Pacific)
• VIC Spatial Digital Twin (Australian State Gov)
• Tokyo Digital Twin
• and many others

This hands-on TerriaJS workshop will walk you through configuring maps, adding your own data, and applying custom branding using JSON configuration files. You’ll also learn how to publish your map on GitHub Pages, making it accessible to others with just a shareable link. Perfect for anyone wanting to present spatial data and stories, no programming skills required.

Participants should bring a laptop with a text editor (such as VSCode) and NodeJS installed. By the end, you’ll have your personalised TerriaJS map running locally and published online via GitHub Pages.
