Bringing MapStore to the Next Dimension: Highlights from the Cesium Developer Conference 2025

Dear Reader,
the Cesium Developer Conference 2025 was more than a gathering of 3D mapping enthusiasts, it was a showcase of what the future of geospatial technology looks like. At GeoSolutions, we were proud to contribute to that vision with a talk by our frontend developer Stefano Bovio, who presented our ongoing work integrating CesiumJS into MapStore, as well as highlights from our Digital Twin Toolbox.
This event marked another important milestone following our recognition as Certified Cesium Developers, affirming our role as leaders in open-source geospatial innovation.
Elevating MapStore with CesiumJS
MapStore has supported CesiumJS since 2016, but in the past few years, we’ve pushed its 3D capabilities even further. Stefano’s presentation demonstrated just how far we’ve come:
- 3D Tiles & Terrain Support: From Cesium Quantized Mesh to IFC and custom 3D models
- Clipping & Map Views: Dynamically isolate features like underground stations or masterplan areas in Genoa
- 3D Measurements & Annotations: Distance calculations, drawing tools, and data-driven labels in immersive 3D scenes
- Styling Engine: Advanced symbology for 3D Tiles and WFS layers based on properties like elevation or building use
Cities like Florence and Genoa were featured throughout the session as real-world examples of how public administrations are already leveraging these features in MapStore to manage urban development, visualize infrastructure, and tell powerful spatial stories.
Digital Twin Toolbox in Action
Another highlight of the session was our Digital Twin Toolbox, a growing suite of integrations designed to support simulation, decision-making, and collaboration. Built on top of MapStore and CesiumJS and other open source tools for 3D Tiles generation, the toolbox allows users to:
- Combine 2D/3D views and synchronize data overlays
- Manage IFC models for infrastructure planning
- Use measurement, annotation, and styling tools interactively

Insights & Inspiration from the Conference
The conference wasn’t just about presenting. It was also a chance to connect, learn, and reflect on trends and conversations that matter:
- Tech in focus: Gaussian splatting, volumetric rendering, Unreal Engine, BIM pipelines
- Deep dive with Cesium staff about 3D Tiles and the shared challenge of BIM data transformation
We also saw how other cities are solving similar challenges which is a confirmation that MapStore is right in the middle of this innovation wave.
What’s Next for MapStore and Cesium
We came away inspired and more committed than ever to:
- Share more impactful use cases and success stories from real-world deployments
- Continue supporting CesiumJS’s roadmap (e.g. OGC API integration, streaming 3D Tiles)
- Push our open-source tools further in digital twin scenarios
As the geospatial world embraces 3D and immersive web experiences, we’re building the tools to make them accessible, open, and powerful.
