This project aims at developping new technologies for the storage and management of 3D geodata related to Urban Digital Twins. It includes a middleware "Cerbere" able to store CityJSON data in a flexible NoSQL document-oriented database while keeping consistency of the standard CityGML data model. Beside the database aspect, the objective is to host a web viewer of 3DGeodata related to the City of Liège and demonstrate the use of Urban Digital Twins technologies through several applications: urban vegetation, air quality, mobility, etc. It is connected to other GeoScITY projects like SEM3D.
