Overview of 3D geoinformation group at TU Delft

Transcript

1. 3D geoinformation group TU Delft

2. Founded in 2015 Faculty of the Built Environment & Architecture

   Department Urbanism Brief overview

3. The team and more soon…

4. Urban environment and 3D geoinformation Our focus

5. 5 Whole North Rhine- Westphalia: 10M+ LoD2 buildings More and

   more 3D data from cities

6. New York City More and more 3D data from cities

7. 7 Helsinki: with textures More and more 3D data from

   cities

8. 8 Whole of the Netherlands: 10M+ LoD1 buildings + terrain,

   roads, forest More and more 3D data from cities

9. Is 3D really useful?

10. Bad reputation in carto + data science

11. Bad reputation in carto + data science

12. solar potential shadow analysis noise modelling energy estimation bomb detonation

    wind turbulence pollutant tracking

13. 13 3D use in mainstream media: NY Times https://www.nytimes.com/interactive/2016/12/21/upshot/Mapping-the-Shadows-of-New-York-City.html

14. Some projects

15. http://3dbag.bk.tudeft.nl PDOK will soon host data

16. LoD2 reconstruction Beta! No open-source yet Live demo https://3d.bk.tudelft.nl/opendata/noise3d/lod13map.html

17. Highly-detailed reconstruction 3D trees from laser scanning 3D buildings from

    drones Check our website for code!

18. 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/

19. Air pollutant tracking/wind turbulence (CFD) Also done with FOSS: OpenFOAM

20. CityJSON: CityGML without the GML

21. ➡ 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
