Land Administration Domain Model (LADM) —
Part 2: Land registration

ISO/PWI 19152-2

This document:

— 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);
— provides an abstract, conceptual model with three packages and one sub-package related to:
      — parties (people and organizations);
      — basic administrative units, rights, responsibilities and restrictions (RRRs);
      — 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);
— 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; — provides a platform for comparison and monitoring that is based on indicators;
— provides a basis for national and regional profiles; and
— 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 with potentially 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.

(Direct support)

ISO 19152‑2 directly supports secure land tenure by enabling standardised documentation and management of land rights. The standard underpins legal security of tenure and supports monitoring of SDG indicator 1.4.2 on land rights.

(Indirect support)

ISO 19152‑2 supports effective, accountable, and transparent institutions by promoting consistent and interoperable land registration practices that strengthen legal certainty and reduce land‑related disputes.

(Indirect support)

ISO 19152‑2 facilitates cooperation among land authorities, governments, and international organisations by providing a shared reference model for land registration data and system interoperability.
