Geographic information - Land Administration Domain Model (LADM) - Part 2: Land registration (ISO 19152-2:2025); English version EN ISO 19152-2:2025
Abstract
This document: a) defines a reference land administration domain model (LADM) covering basic information-related components of land registration (including elements above and below the surface of the earth); b) provides an abstract, conceptual model with three packages and one sub-package related to 1) parties (people and organizations); 2) basic administrative units, rights, responsibilities, and restrictions; 3) spatial units (parcels, and the legal space of buildings and utility networks and other geometry) with a sub-package on surveying and spatial representation (geometry and topology); c) provides terminology for land administration (LA), 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; d) provides a platform for comparison and monitoring that is based on indicators; e) provides a basis for national and regional profiles; and f) enables the combination of land administration information from different sources in a coherent manner. The following is outside the scope of this document: — interference with (national) land administration laws that may have any legal implications; and — construction of external databases with party data, address data, land cover data, physical utility network data, archive data and taxation data. However, the LADM provides stereotype classes for these data sets to indicate which data set elements the LADM expects from these external sources, if available. This document provides the concepts and the detailed structure for standardization in the land administration domain.
