1Dr.ir. Gerben J. de Boer – TU Delft / Van Oord OpenEarth Symposium Connecting data for research - 19 October 2015 2nd round of break-out sessions - Session 1: Working with GIS-data 2Philosophy 2008 3Different layers of standard inspired by Tim Berners-Lee: 5 ★ Open Data Repository: web-based standards 4Repository: proven standards http://1.bp.blogspot.com/-Z8vfA9SmoOg/T84rGCE_XaI/AAAAAAAABLM/Wp2nXaTvrEc/s1600/Amsterdam+086.jp g http://www.bnr.nl/incoming/621827-1301/fyra-578.jpg/ALTERNATES/i/Fyra-578.jpg Use proven and existing technology, avoid being guinee pig for too new standards. Standards mature only after using them (like ERTMS). not too new 5Google Earth overtook all GIS sciences and standards with Google Maps and open 3D kml: use only GPS WGS84. And UTC for times. Enormous complexity of earth-centered system became simple with sun-centered one. Occams’ razor at best. 2015: list of 5 ways to map NL. Which one to choose ? None, use GPS + WGS84. The Earth is round ! Google Earth can handle multiple planets. Now that’s useful meta-data. Repository: current standards not too old 6http://nupedailynews.com/wp-content/uploads/2013/01/telescope..jpg http://chromblog.thermoscientific.com/Portals/49739/images/ lims for biobanking1.png http://oeatech.net/wp-content/uploads/2011/03/RADARSAT2-satellite.jpg suspended mud particle 64 μm 6400 km: North Atlantic Oscillation (NAO) gap 10-6 > 10+6 Water scarcity Flood protection Water pollution http://upload.wikimedia.org/wikipedia/commons/2/22/ Da_Vinci_Vitruve_Luc_Viatour.jpg Marine/coastal scales SPACE CERN Community: as large as possible 72 former PhD students just started OpenEarth by combining their finished work: Mark van Koningsveld (UT: coastal sand) & Gerben de Boer (TUD: marine mud) Social network has grown to 500+ users, incl 3rd world + Fortune 500. Community: social media events/training 8Philosophy: data = raw data + tools Real data sharing implies: • Raw data sharing • Software sharing Earth observation (NASA, ESA, NOAA): L1..L4 = f (L0, g) • L0 data = raw sensor data • L1..L4 = interpretation levels • f = open source software • g = ancillary data (weather) Amazon 9Philosophy: version control http://www.knups.nl/leuk_plaatje/56/Helaas_pindakaas.html 10 Philosophy: shared tool versioning Source code repository has 800+ users and 250+ contributors.
