iTowns is a Three.js-based JavaScript/WebGL framework for visualizing 2D and 3D geospatial data in the browser. It supports OGC protocols and formats such as WMS, WMTS, WFS, TMS, Mapbox Vector Tiles, 3D Tiles, GeoJSON, and point cloud formats like Potree, EPT, and COPC.

Use cases

• display a 3D globe with satellite imagery and terrain elevation in a web app
• visualize point clouds like LiDAR data in the browser
• render 3D Tiles city models or digital twins
• show vector tiles and extrude building footprints in 3D
• build a web mapping application with WMS and WFS layers
• view orthophotos with a digital surface model
• visualize BIM or 3D models over a map

When to choose

• you need 3D globe or planar geospatial visualization in the browser
• you must mix raster, vector, point cloud, and 3D Tiles data in one view
• you want a Three.js-based alternative to Cesium with OGC standards support

When to avoid

• you only need simple 2D slippy maps, where Leaflet or OpenLayers is lighter
• you need native desktop or mobile offline GIS applications
• you require WebGL 1 or legacy browser support
