BSI BS EN ISO 19152-5:2025

—     specifies a reference land administration domain model (LADM) covering basic information-related components of spatial plan information on land/water and elements below/on/above the surface of the Earth with 2D/3D/4D (3D + time) geometric representation;

—     provides an abstract, conceptual model with packages related to:

• plan unit, i.e. the smallest homogenous area/space (2D/3D/4D) with assigned function/purpose, e.g. office, education, retail;
• plan block, i.e. a set of neighbouring plan units decided on by planning authorities, e.g. high-density residential area, nature area, heavy industry area;
• plan group unit, i.e. areas corresponding to the higher planning levels;
• plan group, i.e. hierarchy in spatial plans consisting of multiple plan blocks, e.g.:
  • continent/regional-wide (e.g. European regions),
  • country-wide (e.g. Indonesia, the Netherlands),
  • island,
  • state or region province,
  • municipality or city, and
  • urban or rural;
• permit, i.e. something that is granted to a party which gives the party permission to undertake an activity which would otherwise be restricted;

—     defines terminology for spatial plan information as part of land administration, based on various national and international systems, that is as simple as possible in order to be useful in practice. The terminology allows a shared description of different formal or informal practices and procedures in various jurisdictions;

—     provides a platform for comparison and monitoring of spatial planning information based on Sustainable Development Goal (SDG) indicators;

—     provides an approach to modelling the integration of spatial plan information (outputs of spatial plans) into land administration;

—     provides a basis for national and regional profiles;

—     enables the combining of land-use planning and land development planning in land administration information from different sources in a coherent manner;

—     allows for the relationship to multiple parties and groups to be expressed together with a referencing structure so that the sourcing of all information systems can be maintained. It reuses core LADM classes so that sourcing of all information systems can be maintained;

—     establishes the common elements and basic schema for spatial plan information upon which a more detailed schema can be established.
