Measur3D

A light and compact CityJSON management tool.

This tool is built as a high-level MERN application. It therefore allows developing with a single language in both server and client side. It does not rely on an operating system layer.

3D city models are structured following the CityJSON encoding, a JSON-based encoding for storing 3D city models, also called digital maquettes or digital twins. Thanks to MongooseJS, inserted models are validated in regard of CityJSON 1.0.1 specifications. These specifications define the city model schema used to structure the database (several modifications were however made to suit to document-oriented databases).

Prerequisites

A MongoDB server is mandatory. The choice between MongoDB Atlas, Community or Enterprise Server is left open.

Everything else is packaged in this repository and installed thanks to npm.
