About us

There is unprecedented growth in the amount of 3D geospatial data available. At Cesium, we're building a platform to visualize and make sense of it all.

Cesium is a platform for creating 3D applications that are fast, flexible, and based on real-world geospatial data. Our tools empower developers and data providers to build web-based 3D map experiences that bring together massive datasets, like terrain, photogrammetry, and point clouds, turn them into realistic visualizations, and perform analysis to learn from them. At our core, our tools help you understand your 3D data and use it to gather insights and make better decisions.

We live at the intersection of 3D computer graphics and geospatial: we aspire to make beautiful visualizations of our world and to tie our data to incredibly precise coordinates that allow for accurate measurements down to the millimeter.

We take our name from the element cesium, which powers atomic clocks—the world's most accurate time standards and essential to GPS. We strive to bring the same reliability and precision to time dynamic geospatial data.

Cesium is used every day to understand location data across nearly every industry. Toyota Research Institute uses Cesium to understand data collected from their autonomous cars' sensors. DroneDeploy uses our platform to visualize massive 3D models and point clouds from datasets captured by drone sensors, and Mozilla uses us for 3D geospatial content for its mixed reality web framework.

Today millions of people use Cesium through tools like these, and that number is growing fast. There's incredible value in 3D data. We want to make it and the insights it contains available to everyone.

Our story

In 2011, a team of computer graphics developers at AGI set out to create a way to make scientific visualizations that are accurate, performant, and time-dynamic on the web. We built what became CesiumJS and released it open source.

At the same time, 3D geospatial data started being collected prolifically as sensors got better and became commonplace and citizens pushed for more open data policies. We kept building Cesium on open source and open standards, and worked with the larger graphics and geospatial communities to establish and champion open standards and formats for these huge 3D datasets so more people can access and use this data.

In 2019, Cesium spun out as an independent company to continue enabling developers and data providers to make the best use of their 3D data, and empowering them to create interactive, dynamic 3D geospatial applications.
