3D geoinformation group TU Delft
Founded in 2015 Faculty of the Built Environment & Architecture
Department Urbanism Brief overview
The team and more soon…
Urban environment and 3D geoinformation Our focus
5 Whole North Rhine- Westphalia: 10M+ LoD2 buildings More and
more 3D data from cities
New York City More and more 3D data from cities
7 Helsinki: with textures More and more 3D data from
cities
8 Whole of the Netherlands: 10M+ LoD1 buildings + terrain,
roads, forest More and more 3D data from cities
Is 3D really useful?
Bad reputation in carto + data science

Some projects
http://3dbag.bk.tudeft.nl PDOK will soon host data
LoD2 reconstruction Beta! No open-source yet Live demo https://3d.bk.tudelft.nl/opendata/noise3d/lod13map.html
Highly-detailed reconstruction 3D trees from laser scanning 3D buildings from
drones Check our website for code!
Quality control of 3D city models Automatic repairing of broken
3D city With my colleague John Zhao, we’re making an overview of the most common errors/problems, such as: 12 http://geovalidation.bk.tudelft.nl/val3dity/
Air pollutant tracking/wind turbulence (CFD) Also done with FOSS: OpenFOAM
CityJSON: CityGML without the GML
➡ https://3d.bk.tudelft.nl more info than you probably need! projects, papers,
code, etc 2 courses are open (book+YouTube): • Terrain modelling (AHN) • 3D modelling Thank you
