5. GeoTeχs Geo-information Technology Communication and Consultancy Services Pictometry Characteristics Geo-referenced: ortho + oblique GSD ortho: 15cm GSD oblique: 10 – 18 cm Ortho images  AHN (5m) 30% Overlap (no stereo) Flying Height: 1km Size ortho: 350m x 560m Pricing: € 250 / km2 / annum

6. GeoTeχs Geo-information Technology Communication and Consultancy Services Possible Applications Homeland Security Urban planning Illegal Buildings Fire departments Disaster management Signal propagation Fly-Around Simulations “Our Limit is Your Imagination”

7. GeoTeχs Geo-information Technology Communication and Consultancy Services Research Aim How Pictometry may be of benefit to support the tasks and ambitions of Kadaster: –To be the principal supplier of real estate and geo- information within the Netherlands –Authoritative within Europe

8. GeoTeχs Geo-information Technology Communication and Consultancy Services Research Questions Accuracy? Updating topographic maps? Oblique images  Traditional Photogrammetry? Measuring of cadastral boundaries? Costs?

9. GeoTeχs Geo-information Technology Communication and Consultancy Services Planar Accuracy Ortho: 19cm Oblique: 86cm

10. GeoTeχs Geo-information Technology Communication and Consultancy Services Elevation Accuracy Depends on accuracy AHN –Systematic error 5cm –Random error 15cm

11. GeoTeχs Geo-information Technology Communication and Consultancy Services Fuelling Station/Storage Place

12. GeoTeχs Geo-information Technology Communication and Consultancy Services Which side are the trees?

13. GeoTeχs Geo-information Technology Communication and Consultancy Services Looking Underneath Buildings

14. GeoTeχs Geo-information Technology Communication and Consultancy Services Recognition of non-buildings

15. GeoTeχs Geo-information Technology Communication and Consultancy Services What crosses the Road?

16. GeoTeχs Geo-information Technology Communication and Consultancy Services Third Dimension

17. GeoTeχs Geo-information Technology Communication and Consultancy Services Traditional  Pictometry Advantages -15cm  36 cm -View Underneath Objects -Height measuring tool -(oblique)  attribute assignment -Software is easy and intuitive -Colour Disadvantages -No stereo (at present) -No polygon mapping

18. GeoTeχs Geo-information Technology Communication and Consultancy Services Preliminary Cadastral Boundaries (1)

19. GeoTeχs Geo-information Technology Communication and Consultancy Services Preliminaire Cadastral Boundaries (2)

20. GeoTeχs Geo-information Technology Communication and Consultancy Services Preliminaire Cadastral Boundaries (3)

21. GeoTeχs Geo-information Technology Communication and Consultancy Services Costs Investment; not only cost reduction in existing work processes Beneficial in the long term (production, goodwill, leadership)

22. GeoTeχs Geo-information Technology Communication and Consultancy Services Conclusions Strategic ++ Photogrammetry and oblique images Growth market –Cities 50.000+ –OS, Cadastre Spain –Microsoft local.live.com Catalyser for GII Accurate  Survey tool, not only viewing Standard price: € 250 / km 2 /annum

23. GeoTeχs Geo-information Technology Communication and Consultancy Services Conclusions Strategic -- Stereo images Functionality software, integration GIS Exclusive License Blom (Europe)

24. GeoTeχs Geo-information Technology Communication and Consultancy Services Conclusions Pictometry Tactical/Operational ++ Identifying preliminary boundaries via notary Building registration Communication citizens and government Maintenance topographic maps – if stereo Add on to Top Map 3D City Models Easy, intuitive interface, very accessible Navigation tool for entering databases (e.g. building registration, WOZ)

25. GeoTeχs Geo-information Technology Communication and Consultancy Services Conclusions Pictometry Tactical/Operational -- Additional functionality required Footprint difficult identifiable System needs DEM – not if stereo images No integrated aero-triangulation

26. GeoTeχs Geo-information Technology Communication and Consultancy Services Preliminary Boundaries
