  1. Land Administration Domain Model (LADM, ISO 19152)Spatial Unit Package and Spatial Profiles Peter van Oosterom ISO/TC211, LADM workshop, Québec,Canada, 4 November 2009

  2. Content • Introduction • Spatial Unit • Spatial Representation/Survey • Spatial profiles • Conclusion

  3. ISO 19152 Scope • reference model (abstract, conceptual schema) • land/water, below/above surface • basic classes: (1) parties, (2) rights, responsibilities, and restrictions, (3) spatial units, (4) spatial sources, and (5) spatial representations • terminology enabling communication • shared description of formal or informal practices • basis for national, and regional profiles (application schema) • blueprint stereotype for classes in external databases: person, address, data, data, and taxation data • no interference with (national) land administration laws

  4. LADM core: new name LA_BAUnit • explicit modeling ‘real estates’; e.g. LA_Party Peter has LA_RRR ownership on LA_BAUnit Peter’s estate consisting of 2 LA_SpatialUnit parcels (with same LA_RRR) • LA_BAUnit stands for Basic Administration Unit

  5. Content • Introduction • Spatial Unit • Spatial Representation/Survey • Spatial profiles • Conclusion

  6. LA_SpatialUnit (alias LA_Parcel) • LA_SpatialUnit specializations: network, building unit • organized in LA_Layer based on structure or content • 5 types: point, text (unstructured) line, polygon, and topology • 2D and 3D integrated without complicating 2D

  7. Content • Introduction • Spatial Unit • Spatial Representation/Survey • Spatial profiles • Conclusion

  8. Spatial Representation and Survey subpackages of SpatialUnit • Geometry, topology of Spatial Units (based ISO 19107) • Spatial source (based ISO/CD 19156 Observations and Measurements)

  9. 2D and 3D integration • observation: 2D description implies 3D prismatic volume • 2D polyline (GM_curve) implies string of vertical faces

  10. 2D and 3D integration • 2D polyline (GM_curve) implies string of vertical faces: LA_BoundaryFaceString • true 3D described with arbitrary oriented faces: LA_BoundaryFace

  11. Code lists • Typical example values • Not limited to given values • Can be extended in country profiles

  12. 2D and 3D integration • between 2D and 3D spatial unit transition via liminal spatial units

  13. Introduction of LA_Layer • organization based on content or structure: • example 1, content-based: one layer with ‘primary’ (strongest) rights, another layer with rights that can be added/subtracted (e.g. restrictions) • example 2, structure-based: one layer with topologically structured parcels (one part of the country), another layer with (unstructured) line based parcels (other part of country) • can also be used in 3D context:one layer ‘normal’ parcels, anotherlayer with subtracted 3D parcels • based on independence principle • each country design own layers

  14. Content • Introduction • Spatial Unit • Spatial Representation/Survey • Spatial profiles • Conclusion

  15. ISO 19152 Annexes • Abstract Test Suite • Social Tenure Domain Model • Instance Level Cases • Country Profiles • Spatial Profiles • Legal Profiles • LADM and INSPIRE (Cadastral Parcels) • LADM and LPIS (Agricultural Parcels)

  16. Spatial profiles fill-in the options • Text • Point • Unstructured line • Polygon • Topology • 2D • 3D • Mixed  Gives 5 times 3 options (15 in total), now 3 examples

  17. Point based (2D) The following classes should be omitted • LA_BoundaryFaceString; • LA_BoundaryFace

  18. Unstructured line based (2D) The following classes should be omitted • LA_BoundaryFaceString

  19. Examples from the Queensland DCDB • Original boundaries • No splitting • Compact

  20. Topology based (3D) The following class is omitted • LA_BoundaryFaceString

  21. Content • Introduction • Spatial Unit • Spatial Representation/Survey • Spatial profiles • Conclusion

  22. Conclusion • Spatial Unit is one package with two subpackages (Survey and Spatial Representation) • Spatial Units are universal in their land administration application (ownership, easement, utilities, building,..) • Range of representations: text  3D topology • Based on other ISO standards ISO19107 and ISO19156 • Integrate 2D and 3D representations
