What is CityJSON?

CityJSON is a JSON-based encoding for a subset of the OGC CityGML data model (version 3.0.0), which is an open standardised data model and exchange format (in GML) to store digital 3D models of cities and landscapes.

The aim of CityJSON is to offer an alternative to the GML encoding of CityGML, which can be verbose and complex (and thus rather frustrating to work with). CityJSON aims at being easy-to-use, both for reading datasets, and for creating them. It was designed with programmers in mind, so that tools and APIs supporting it can be quickly built, and several software have been created already.

Contributing to the project

We invite anyone to contribute to the development and improvement of CityJSON, all discussions, issues, and developments are open to everyone.
