Step into the ionosphere at the 2026 Cesium Developer Conference
The 2026 Cesium Developer Conference, June 8-10 in Philadelphia, brings together the developer community to learn, share, and build what’s next in 3D geospatial. This year, we’re introducing a new space designed to make those connections even easier: the ionosphere.
A new gathering space at the Cesium Developer Conference
The best ideas often come from connection between developers, product teams, and the community to push the limits of what’s possible with 3D geospatial technology.
The ionosphere is a new dedicated area to support those conversations. It’s a place where attendees can connect directly with the engineers and product teams building the tools they use every day.
Whether you want to ask a deep technical question, explore a new workflow, or see the latest features in action, the ionosphere is designed to make those interactions easier and more accessible.
Cesium's technical team will be on hand at the 2026 Cesium Developer Conference to share insights, discuss projects, explore the latest Cesium features, and more.
Innovate with the experts behind Cesium and iTwin
In the ionosphere, you’ll have the opportunity to meet the teams working on tech powering the open 3D geospatial ecosystem.
Attendees can connect with experts from:
- Native Runtimes
- CesiumJS
- iTwin Capture
- 3D Tiles
- Cesium ion
- Design Data Workflows
These sessions are intentionally informal. Drop by to ask questions, discuss your projects, and get insights directly from the people building the platform.
Join us at Dev Con 2026
The 2026 Cesium Developer Conference will be packed with technical sessions, community presentations, and expanded opportunities to connect with practitioners and decision-makers across 3D geospatial.
If you’re building with 3D geospatial technology—or want to start—join us June 8-10 to learn, connect, and explore what’s possible.
