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
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
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!
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
