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.
Stream high-resolution global terrain using the open quantized-mesh format or traditional height-maps, or plug in your own.
Load KML, GeoJSON, TopoJSON, and CZML. Use the Cesium API directly to draw a wide array of features and geometries.
See our first-class support for high-fidelity time-dynamic simulation, real-time telemetry streaming, and 4D visualization.
