Overview

Our mission is to create the leading web-based globe and map for visualizing dynamic data. We strive for the best possible performance, precision, visual quality, ease of use, platform support, and content.

Global Terrain

Stream high-resolution global terrain using the open quantized-mesh format or traditional height-maps, or plug in your own.

Imagery Layers

Stream imagery using a wide array of open standards and custom tiling schemes.

3D Models

Visualize 3D models using glTF, the runtime asset format for WebGL.

Vectors and Geometry

Load KML, GeoJSON, TopoJSON, and CZML. Use the Cesium API directly to draw a wide array of features and geometries.

Time-Dynamic Visualization

See our first-class support for high-fidelity time-dynamic simulation, real-time telemetry streaming, and 4D visualization.

3D, 2D, and 2.5D Columbus View

Use one API for three views.
