3D data become more and more common these days. Sensors like drones or "streetview" cars produce large amounts of images used to create 3D models through photogrammetry. 3D editing software also eases the production of 3D models, especially for BIM. AI systems begin to be ready to generate 3D objects of the world.

It is now frequent for municipalities to acquire a full 3D dataset of all urban objects. These datasets pose a certain amount of issues : how to visualize them efficiently ? How to integrate these 3D data with other GIS data ? How to make them available on the web ? How to manage this data with my favorite GIS software ?

We worked on these issues in order to be able to manage urban data efficiently in QGIS. Based on the emerging 3D capabilities of QGIS, we explored the 3D Tiles format and implemented it in QGIS, so as to be able to visualize large amount of urban data.

In this presentation, we will present our work on urban data visualization, the state of the art in QGIS 3D visualization, and future work planned in this area. We will showcase the features with a real-world example.
