1 GeoTeχs Geo-information Technology Communication and Consultancy Services Pictometry Mathias Lemmens Christiaan Lemmen Martin Wubbe (The Netherlands) (paper 2521) 6th FIG Regional Conference November 2007, San José, Costa Rica

2 GeoTeχs Geo-information Technology Communication and Consultancy Services Agenda Introduction Pictometry Goals Results Conclusions Recommended Pilots

3 GeoTeχs Geo-information Technology Communication and Consultancy Services Tasks of the Cadastre Registration, management and releasing title information and geo-information Land development Managing the national geodetic framework Providing information products Carrying out international activities Total Number of Parcels Registered8,568,274 Number of registered transaction acts in ,200 Number of registered mortgage acts in ,900 Number of information requests (2005)18,907,473

4 GeoTeχs Geo-information Technology Communication and Consultancy Services

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 –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

27 GeoTeχs Geo-information Technology Communication and Consultancy Services

28 GeoTeχs Geo-information Technology Communication and Consultancy Services 1. Identification of boundaries in Notary office Prerequisites –Notary, representative sample of deeds, PC + software, HR, data, € ,-- Expected Results –Better spatial orientation for parties –No identification in the field (50%) –Immediate Parcel Creation –New template for surveyor

29 GeoTeχs Geo-information Technology Communication and Consultancy Services 2. Building Registration: suitability test with BAG designers Prerequisites –stereo pictometry, representative part of a Dutch city, DPW, software, HR, BAG designers, data, € ,-- Expected Results –Desired / collectable data –Navigation tool Additional Benefit –pro-active attitude towards VROM

30 GeoTeχs Geo-information Technology Communication and Consultancy Services 3. Pictometry as navigation tool in cadastral portal Prerequisites –Extending KOL (prototype), HR, PC+software, data, sessions with customers, € ,-- Expected Results –Customer’s reactions –easier access to data (e.g. BAG, WOZ) –overview of potential products and applications

31 GeoTeχs Geo-information Technology Communication and Consultancy Services Thank You for your Kind Attention
