  1. Overview of @tudelft3d efforts regarding open data/software/science Hugo Ledoux 2018-11–01

    VU, Amsterdam, NL
  2. 3D geoinformation group @ TU Delft 2 • since 2015

    • 4 tenured staff (soon 5) • 3 postdocs • 9 PhDs • many diff backgrounds
  3. Our focus: urban environment and 3D geo-data 3 Designing, developing,

    and implementing better systems to reconstruct, model, and analyse 3D cities, buildings, and landscapes
  4. None
  5. None
  6. Residential building Jaffalaan 9, Delft owner: Jan Smit 120m2 1824

    Park “de tuin” 800m2 Canal “de Schie” depth = 3.34m
  7. 7 solar potential shadow analysis noise modelling energy estimation bomb

    detonation wind turbulence pollutant tracking
  8. Standardisation of 3D geoinformation 8

  9. Open software?

  10. All (most?) of our code is online 10

  11. All (most?) of our code is online 11

  12. 12 • your work reach practitioners • insight into practitioners’

    work • gives us new funding opportunities • NL/EU grants favour open-source software • you can build up open-source libraries • personally, I’m more “complete”, I relate more to students • journals increasingly request code/data Good things about open software
  13. None
  14. […] referees have the right to view the data and

    code that underlie a work […], even if these have not been provided
  15. 15 • takes time • takes a lot of time

    • often thankless work (you hear only when it crashes) • some people think you work for free • no “brownie points” at unis (changing quickly though) Less good things about open software
  16. Open data?

  17. 17 Standards are super important for us

  18. 18 Standards are super important for us since 1990s we

    have int’l efforts, otherwise nothing would work…
  19. Open geo-data? NL is paradijs! 19

  20. Open geo-data? NL is paradijs! 20 BUT: mostly 2D datasets!

  21. None
  22. AHN dataset Actueel Hoogtebestand Nederland www.ahn.nl

  23. Whole NL == ~700 billion points 23

  24. 3dfier: our software to reconstruct 3D for apps 24

  25. We distribute some datasets on our website 25

  26. We helped Kadaster reconstruct the whole NL in 3D 26

  27. We helped Kadaster reconstruct the whole NL in 3D 27

  28. —> structured & searchable data repository 28

  29. 3DBAG: buildings 29

  30. 3DBAG: buildings at diff heights 30

  31. 31 • way easier to publish papers, teach, share •

    reproducible science: you give data with paper • you help other researchers, you create collaborations • please be “good scientists”: you use? you give back! Good things about using open data
  32. Open science?

  33. 3D geoinformation group @ TU Delft 33

  34. 3D geoinformation group @ TU Delft 34

  35. Its code is also open for anyone to see 35

  36. Its code is also open for anyone to see 36

    everyone in the group can edit it
  37. Sometimes it backfires though… 37

  38. Make author’s versions of all your papers 38

  39. Make repositories for data/code 39

  40. thank you. h.ledoux@tudelft.nl 3d.bk.tudelft.nl/hledoux Hugo Ledoux @tudelft3d 3d.bk.tudelft.nl @tudeflt3d github.com/tudelft3d
