CesiumJS is an open-source JavaScript library for rendering high-precision 3D globes and 2D maps in the browser using WebGL. It supports streaming 3D Tiles, terrain, imagery, glTF models, and time-dynamic geospatial data at massive scale.

Use cases

• render a 3d globe in a web app
• visualize 3d buildings and photogrammetry with 3d tiles
• stream terrain and satellite imagery layers in the browser
• display time-dynamic flight or vehicle telemetry on a map
• load kml geojson or czml geospatial data
• build a smart city or drone tracking dashboard
• view gltf 3d models on a globe

When to choose

• you need high-precision WGS84 3D globe rendering in the browser
• you must stream massive 3D Tiles, terrain, or imagery datasets
• you need time-dynamic 4D visualization of geospatial data
• you want an Apache-2.0 library with commercial-friendly licensing

When to avoid

• you only need simple 2D slippy maps without 3D (Leaflet or MapLibre may suffice)
• you need offline desktop GIS analysis rather than web visualization
• you cannot rely on any network tile or terrain streaming sources
