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


Content

  • Introduction

  • Spatial Unit

  • Spatial Representation/Survey

  • Spatial profiles

  • Conclusion


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


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


Content

  • Introduction

  • Spatial Unit

  • Spatial Representation/Survey

  • Spatial profiles

  • Conclusion


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


Content

  • Introduction

  • Spatial Unit

  • Spatial Representation/Survey

  • Spatial profiles

  • Conclusion


Spatial Representation and Survey subpackages of SpatialUnit

  • Geometry, topology of Spatial Units (based ISO 19107)

  • Spatial source (based ISO/CD 19156 Observations and Measurements)


2D and 3D integration

  • observation: 2D description implies 3D prismatic volume

  • 2D polyline (GM_curve) implies string of vertical faces


2D and 3D integration

  • 2D polyline (GM_curve) implies string of vertical faces: LA_BoundaryFaceString

  • true 3D described with arbitrary oriented faces: LA_BoundaryFace


Code lists

  • Typical example values

  • Not limited to given values

  • Can be extended in country profiles


2D and 3D integration

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


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


Content

  • Introduction

  • Spatial Unit

  • Spatial Representation/Survey

  • Spatial profiles

  • Conclusion


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)


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


Point based (2D)

The following classes should be omitted

  • LA_BoundaryFaceString;

  • LA_BoundaryFace


Unstructured line based (2D)

The following classes should be omitted

  • LA_BoundaryFaceString


Examples from the Queensland DCDB

  • Original boundaries

  • No splitting

  • Compact


Topology based (3D)

The following class is omitted

  • LA_BoundaryFaceString


Content

  • Introduction

  • Spatial Unit

  • Spatial Representation/Survey

  • Spatial profiles

  • Conclusion


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
