3D geoinformation group shines at 3DGeoinfo - ⚡ Camilo wins Best Young Researcher Award.
Oct 1, 2025

On September 2-5 2025, our research group participated in the joint conference of the 20th International 3D GeoInfo and the 9th International Smart Data and Smart Cities hosted by the Center of Spatial Information Science at the University of Tokyo.

We presented eight publications covering diverse aspects of 3D geoinformation:

• Enriching LoD2 Building Models with Facade Openings Using Oblique Imagery
• RoofSense: A Multimodal Semantic Segmentation Dataset for Roofing Material Classification
• FlatCityBuf: a new cloud-optimised CityJSON format
• Semantic segmentation of point clouds with the 3D medial axis transform
• A proposal to update and enhance the CityGML Energy Application Domain Extension
• Lessons learnt from the integration of open data and semantic 3D city models for urban building energy modelling in the Netherlands
• Data-Driven Energy Simulations To Evaluate Positive Energy District Potential in Rotterdam
• Introducing server-side support for 3DCityDB 5.0 to the 3DCityDB-Tools plug-in for QGIS

Additionally, our colleague Clara García-Sánchez delivered a keynote speech sharing insights on advancing 3D modeling techniques for with a focus on urban flow simulations.

Finally, we are proud to announce that our colleague Camilo León-Sánchez won the Best Young Researcher Award at the 9th Smart Data Smart Cities conference for his paper “Lessons learnt from the integration of open data and semantic 3D city models for urban building energy modelling in the Netherlands”.

This publication presents valuable insights from the integration of open datasets in the Netherlands for the creation of a country-wide enriched semantic 3D city model for urban building energy modelling.

Congratulations to Camilo and his co-authors!
