Geographic information - Land Administration Domain Model (LADM) Part 2: Land registration

The objectives of this document are to –

1. define 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);
2. provide 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 (RRRs);
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);
3. provide 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;
4. provide a platform for comparison and monitoring that is based on indicators;
5. provide a basis for national and regional profiles; and
6. enable the combination of land administration information from different sources in a coherent manner.

This document is identical to and has been reproduced from, ISO 19152‑2 Geographic information – Land Administration Domain Model (LADM) – Part 2: Land registration.
