Convert JSON File

JSON CityJSON File

A modern, JSON based (JavaScript Object Notation) file format designed for storing 3D city models. It efficiently represents buildings, roads, bridges, and other urban features with support for textures, semantics, and metadata.

Key Features of CityJSON

• JSON-Based:

  Lightweight, human-readable, and easy to parse (no complex XML like CityGML).

• Semantic Richness:

  Preserves object attributes (e.g., building heights, roof types, road classifications).

• LOD Support:

  Stores multiple Levels of Detail (LOD1 - LOD4) for flexible use cases.

• Web-Ready:

  Works seamlessly with JavaScript, APIs, and 3D web viewers (like Cesium or Three.js).

• Open Standard:

  Developed and maintained by the 3D Geoinformation Group (Delft University).
