Cesium began in 2011, when a team of developers at aerospace software company Analytical Graphics, Inc. set out to create an application to visualize objects tracked in space. Led by computer graphics expert Patrick Cozzi, the project produced the world's most accurate, performant, and time-dynamic virtual globe. Dubbed Cesium after the element that makes atomic clocks famously accurate, it was released as open source in 2012.
At the same time, 3D data collection was proliferating around the world, driving a need for software and standards that could unleash its potential. Cozzi and the Cesium team created 3D Tiles, now an OGC Community Standard , to support visualization of massive, precise 3D data at a global scale. As industries began gathering 3D location data for an abundance of use cases, the team saw the demand to expand Cesium beyond aerospace. In 2019 Cesium spun out as an independent company with the vision to build the foundational open platform for the entire geospatial ecosystem.
Expanding on the visualization capabilities of CesiumJS, which the company still maintains as free open-source software, the Cesium platform is now a complete suite of tools for building 3D geospatial applications of any kind. The Cesium platform includes curated 3D data, precise tools for measurement and analysis, and 3D tiling pipelines that make 3D data easy to stream and share.
Applications built with Cesium are used for everything from planning flights and building digital twins for smart cities to helping autonomous vehicles navigate the world. Cesium is proud to serve a wide range of customers and partners across industry and government, including the United States Department of Defense and companies like Uber, JLL, and Komatsu.
