This conference offers developers from the open geospatial community the opportunity to exchange ideas on open technologies such as 3D Tiles, OpenUSD, glTF, iTwins, IFC, as well as game and graphics engines. Participants will discuss their applications in areas such as architecture, engineering, construction, aerospace, and climate technology.

Our experts Jannes Bolling and Ben Kuster will be on site. Ben will be giving a talk on our new panoramic viewer, which is currently in development, on June 24 at 11:20 AM. You can find the program here.

Talk description:

VC Map Panorama: High Resolution Panoramic Images with Cesium

Panoramic images are a great way for users to explore a location without having to be there in person. They give a detailed view of the surroundings and can be used for various purposes such as site inspections and urban planning. By leveraging the GIS capabilities of the free and open-source VC Map framework and the 3D visualization power of Cesium, we can create an open-source tool that goes beyond simply viewing panoramic images.

Our goal is to provide a seamless experience for users to explore, analyze and navigate their 3D, 2D and panoramic data within a single application.

Part of this work included developing a tiled data specification with the goal of minimizing the need for file transfers and boosting performance.

This specification is built on cloud-ready OGC standards – Cloud Optimized GeoTIFF (COG) and FlatGeobuf. The images are rendered directly into the 3D scene, which allows to blend in visualizations of GIS data from the 3D scene.

To enable analytical tools, such as measurements, additional depth information is used. With this development we aim to further the Cesium ecosystem and demonstrate how the Cesium API can be used for this unconventional GIS application.

Our technologies enable the visualization and analysis of complex spatial data, which supports well-informed decision-making in areas such as urban planning, mobility, and environmental management. By integrating geodata into digital twins, we lay the foundation for transparent and participatory planning processes.

We look forward to valuable exchanges and are excited about the insights that the Cesium Developer Conference 2025 will provide for the future of open geospatial technologies.
