Cesium lets you build real world 3D data into your apps

3D data is being collected at astonishing rates. But while satellites, land vehicles, and drones are busy gathering this information, it remains difficult to use. Cesium is an end-to-end platform that unleashes the potential of 3D data by making it easy for developers to visualize, analyze, and share 3D content.

3D from the ground up

3D is not 2D + 1. Cesium preserves the 3D context to provide key spatial insights in your data.


We first built Cesium to track satellites orbiting the Earth, and we couldn't afford to be off a millimeter. Precision is baked into every component of Cesium.

High performance

3D geospatial datasets are among the biggest of the big data. Using cloud computing, parallel programming, and GPUs, we build everything with performance in mind.


Cesium is built with extensive APIs and open standards so developers can build unique tools for their specific industry needs.


At its core Cesium is an open platform, and we adopt, contribute to, and create open standards with industry consortiums to facilitate collaboration.

Data fusion–friendly

Cesium can layer together data from multiple sources, visualize it as one, and run advanced analytics on the unit.

Time dynamic

Whether you're tracking changes in a war zone or after a natural disaster, Cesium allows you to see variances over time.

An End-To-End 3D Geospatial Solution

Cesium is a complete platform for 3D geospatial data—handling everything from optimization to visualization to analytics. At the heart of our platform is 3D tiling, which transforms massive and diverse 3D geospatial data into streamable 3D content ready to be used in your application and in any environment.

More and more people are using Cesium, across industries and for many different purposes. The Toyota Research Institute uses Cesium to create accurate simulations of road environments captured by sensors on its autonomous vehicles. Propellor uses Cesium to visualize ultra high resolution digital twins from drone data for remote site inspections, and each year NORAD, one of our earliest adopters, uses Cesium to track Santa's path around the world on Christmas Eve.

Why Cesium?

Making 3D data accessible

We make 3D geosptial data easier to visualize, share, and understand by allowing you to bring your own data into Cesium and fuse it with a growing number of 3D data sets that we provide directly or through our partnerships.

Bring your own data

Cesium's robust and performant pipelines tile your data and stream it in 3D in the cloud or on private networks - whether you have point clouds, photogrammetry, CityGML, 3D buildings, BIM, CAD, design models, terrain, or imagery.

Curated data

Search through our growing library of curated data for base layers, such as global terrain, that can act as a canvas for your own data in Cesium.

Data partners

We collaborate with data partners to provide additional datasets for use in Cesium and to combine with your own data.

The Power of 3D Tiles

We created 3D Tiles, now an OGC Community Standard , to address the need for formats that are specifically designed for 3D geospatial visualization and massive, precise 3D data at a global scale. 3D Tiles is at the core of our pipelines, and thanks to its interoperability with other platforms and tools, its adoption is growing across industries. As the creators of 3D Tiles, Cesium is uniquely equipped to leverage it for optimal tiling, streaming, and visualization.

Enterprise Solutions

Many of the tools and features that power our cloud platform are also available for offline and on-premise use. Contact our sales team to discuss what your project needs - we're happy to find the best solution for you.
