We are thrilled to announce the return of the Cesium Developer Conference, taking place June 8-10, 2026, in Philadelphia, PA, USA, at the Loews Hotel. Join us to connect with fellow developers and innovators from around the globe who are shaping the future of open geospatial technologies.

The 2026 Cesium Developer Conference is a unique opportunity for the community to come together, share ideas, and collaborate on solving real-world challenges. We invite you to be a part of the conversation by submitting a presentation proposal. The call for presentations is open now, January 5, through Friday, January 30.

Inspire the community with your work

We are looking for engaging, technically oriented presentations that showcase the incredible work being done across 3D geospatial. Whether you're pushing the boundaries of 3D, AI, and data technology, transforming AEC and digital twin workflows, or pioneering new applications in aerospace and defense, we want to hear from you.

What to expect

Last year's conference featured a wide range of inspiring sessions, including:

  • "A Cesium-Based Web Application for Accessing NOAA Scientific Data"
  • "Accelerating AEC Workflows with 3D Geospatial Context in Runtime Engines"
  • "Gaussian Splatting with 3D Tiles and glTF"
  • "High Fidelity NASA Surface Operations for Astronaut Training Using Cesium Moon"
  • “One World Terrain’s Well Formed Format 2025”

This year, we look forward to another lineup of groundbreaking presentations from the community. We encourage both full-length talks (20 minutes) and lightning talks (5 minutes) that highlight your innovations and experiences with 3D creation engines, CesiumJS, iTwin, 3D Tiles, interoperability, and openness. Submit your presentation here; the submission window will close end of day on January 30, 2026.
