Key features

Swiss army knife for geographic data

iTowns offers a comprehensive toolkit for visualizing, interacting and composing diverse spatial datasets. Mix point clouds, terrain, orthophotos and vector data in a single view!

Easily extend the engine for your needs
Build your application from simple blocks

Multiple format support

OGC 3D Tiles

Rely on 3DTilesRendererJS to support streams of point clouds and batches of heterogeneous 3D models. Visualize and interact with massive datasets such as urban infrastructure.

See 3DTilesRendererJS repo

2D GIS formats

Retrieve aerial images or terrain tiles from OGC mapping services, and render vector data from GeoJSON, KML, or Mapbox Vector Tiles. Add depth to your vector data by extruding it!

Mapbox Vector Tile (MVT) and Style

Handles Mapbox Vector Tile (MVT) datasets along with its styling. iTowns stylization mechanism allows you to easily stylize the rendered data according to your preferences.

Point clouds

Native integration of the most widely used point cloud formats, including Potree, Entwine and COPC. Effortlessly visualize the outcomes of your acquisition and fine-tune the visualization to your needs.
