This document: — 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.
