Cesium
Cesium is an open source and SaaS software infrastructure designed to visualize and analyze 3D geospatial data on a global scale. It is rapidly gaining popularity thanks to tools such as CesiumJS, Cesium ion, and integrations with engines such as Unreal, Unity, and NVIDIA Omniverse.
Cesium's Offering: Open & Scalable
CesiumJS, the open-source JavaScript library released under the Apache 2.0 license, allows you to develop navigable 3D maps and globes directly in your browser, supporting streaming of complex datasets via the standardized 3D Tiles format. The commercial Cesium ion service adds optimized pipelines, secure hosting, and ready-to-use global content, such as 3D models, terrain, and satellite imagery.
Real-world experiences in infrastructure & smart city sectors
Cesium is used by global companies such as Komatsu, government agencies, environmental agencies, and universities for urban simulations, infrastructure monitoring, digital twins, and operational planning. It is also known for large-scale applications such as the NORAD Tracks Santa project and NBC's summer sports coverage, which leveraged the capabilities of the Cesium 3D globe.
Cesium was the promoter of the 3D Tiles standard adopted by the OGC (Open Geospatial Consortium), ensuring scalability, rendering efficiency, and compatibility with formats such as glTF, CZML, GeoJSON, and KML. The ecosystem is supported by open source libraries and integrations with engines such as Unreal, Unity, Omniverse, and O3DE.
Cesium is the ideal platform for applications that require high-fidelity 3D representations and real-time data management on a large scale. Thanks to its open, modular, and interoperable approach, the system is perfect for scenarios related to infrastructure, digital twins, urban planning, environmental monitoring, and smart mobility.
