The Importance of Authoritative Geo-data for Daily Work

Learn how authoritative geo-data, organized in key registers, is crucial for various public bodies in the Netherlands. Discover the benefits, implementation process, and the guarantee of continuity of this system. Explore the connection between key registers and other information, as well as the role of open geo-data in the national spatial data infrastructure.

  1. How and why authoritative geo-data help us in our daily work Martin Salzmann Cadastre, Land Registry and Mapping Agency of the Netherlands (Kadaster)

  2. Cables and pipelines Cadastre, Land Registry and Mapping Agency

  3. Authoritative data in the Netherlands • Organised in so-called key registers • 13 key registers (7 with geo-information) • Implementation of system takes years(has a large effect on working processes) • Use by public bodies is compulsory • Defined quality of data and relations between objects(results in harmonisation) • Other information can be linked to data key registers • Continuity (funding) guaranteed (political risk) • Geo-data largely open data (available and accessible) • System underlies NSDI (together with INSPIRE)

  4. Key facilities Kadaster Key register cadastre (*) Key register topography (*) Information node public restrictions Information node buildings and addresses (*) Information node large scale topography (*) Information node valuation (*) Information node planning/zoning Information node cables and pipelines Information node PDOK (Inspire) (* = directly related to key register)

  5. PDOK creating a national information point for the national spatial data infrastructure (NSDI), open geo data and INSPIRE

  6. basic service: createyourown map crowdsourced data part of product end user: consumerand producer

  7. Information created more easily Public real estate by Kadaster-Municipalities Analysis of municipality of Vlaardingen

  8. Registration of networks Registrationbased on key register cadastre

  9. Innovation in geographic informationcreating a 3D topographic map (LOD-0): Combination key register with national height dataset

  10. Statistical application Statistics Netherlands: since 2012 use of key register buildings and addresses No more sampling Slight change of definitions;discontinuities of time series Trust in availability, quality andcompleteness of data Will gradually rely on morekey registers (e.g. valuation)

  11. Key register of subsoil Utrecht Amersfoort 50m Antropogeen Veen Klei Kleiig zand & zandige klei Fijn zand Matig grof zand Veenendaal Grof zand Grind

  12. Use of subsoil information Geological Survey of the Netherlands: key register based on voxels (3D) Model is e.g. basis for groundwater modelling by waterboards Waterboards can focus on their core business

  13. Witte kaart (‘white map’)national facility care centresforeffective response in crisis situations (safetyand health regions) Authoritative data ofkey registers combinedwith information ofsafety and health regions

  14. Considerations for the future • How adaptive will key registers be? • How sustainable are authoritative data?- funding- quality- adaptation to users’ needs • How is access and availability warranted in the long run? • How can other parties (consumers, citizens, professionals) contribute to information society and authoritative data?

  15. Simple world of authoritative data Formal data Informal Data
