[FOSS4G 2025 Auckland] Terra Draw - cross-platform drawing library for all map applications Workshop
Event: FOSS4G 2025 Auckland, Auckland, New Zealand
Terra Draw is a drawing library for cross-platform mapping libraries such as MapLibre, Leaflet, OpenLayers, Mapbox, Google Maps and ArcGIS. It provides a unified API, so developers can build drawing features with the same code across different web mapping libraries.
This 3-hour workshop consisted of two parts:
- Introduction: a presentation on what Terra Draw is and what it can do for map applications.
- Hands-on: coding exercises integrating Terra Draw with MapLibre GL JS, including
- installation and setup of Terra Draw
- advanced functionalities such as layer styling and events
- the maplibre-gl-terradraw plugin to add a pre-configured drawing control in one line
The workshop also showed how Terra Draw can be used with other mapping libraries, demonstrating its adaptability across platforms. Participants brought laptops with Node.js v22 LTS and VSCode.
