  1. 3D4EM Validation of 3DTOP10NL Hugo Ledoux 2015-11-11 User’s committee meeting,

    Utrecht

  2. 3D top10NL 2

  3. None

  4. How good is it?

  5. visible errors

  6. construction = intricate workflow 6 ITC/Sander’s code FME + ArcGIS

    output

  7. Now freely available online 7 http://www.arcgis.com/home/webmap/viewer.html?layers=15acccc56e6a462ab7b79a9d5c6d4933&useExisting=1

  8. None
  9. None

  10. ALL triangles are duplicated !

  11. often big parts of tiles are missing 11

  12. some classes are not triangulated 12

  13. triangulation has several long and skinny triangles 13

  14. Vertical triangles have often the wrong orientation 14

  15. TOP10NL polygons are arbitrarily split 15

  16. borders of top10nl tiles 16

  17. ALL buildings are geometrically invalid 17

  18. Some numbers 18 8,5% of regions

  19. Are these errors a problem for you?

  20. They were for us!

  21. 3dfier An open-source toolkit to construct large 3D city models

  22. None

  23. 23 • open-source libraries used: ‣ liblas, GDAL, Boost.Geometry, Triangle

    • scalable and fast (C++) ‣ our aim is to construct whole NL on our server • configurable: any input would work (3DBGT!) • valid output
  24. None

  25. Far from finished 25

  26. thank you. [email protected] 3d.bk.tudelft.nl/hledoux Hugo Ledoux
