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.

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 hundreds of thousands 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, CesiumGS 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.

2011 Cesium is founded by a team of computer graphics developers at AGI.
April 2012 CesiumJS is released as open source.
December 2012 NORAD Tracks Santa uses CesiumJS for its annual tradition of tracking Santa's route around the world.
March 2013 CesiumJS adds support for streaming global terrain data, introducing the open quantized-mesh format for efficient streaming, decoding, and rendering of terrain.
March 2014 CesiumJS adds support for 3D models using the glTF open standard, marking the beginning of our leadership within standards groups.
August 2014 CesiumJS 1.0 is released after 28 beta releases and with contributions from 33 contributors.
August 2015 3D Tiles is introduced to improve streaming and rendering performance of massive heterogeneous datasets, bringing a new open specification to 3D geospatial.
October 2015 glTF 1.0 specification for 3D models is released, a collaboration between the Cesium team, the Khronos Group, NVIDIA, and many others.
December 2016 CesiumJS reaches 100 contributors. This amazing community is why we believe so deeply in the strength of open source.
June 2017 glTF 2.0 is released with significant new functionality and huge adoption: Microsoft, Google, NVIDIA, Oculus, and many others. We helped champion this release and its adoption.
May 2018 Cesium ion launches, providing a complete platform to host, visualize, and analyze 3D content.
February 2019 3D Tiles becomes an OGC community standard, making it the standard for 3D geospatial.
June 2019 Cesium GS spun out as an independent company.
