UNE-EN ISO 19152-1:2024

This document:

defines a reference Land Administration Domain Model (LADM) covering basic information-related

components of land administration/georegulation;

provides an abstract, conceptual model with packages related to:

parties (people and organizations);

basic administrative units, rights, responsibilities, and restrictions;

spatial units.

provides terminology for land administration/georegulation, 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 indicators-based comparison and monitoring;

provides a content model independent of encoding, allowing for the support of various encodings;

provides a basis for national and regional profiles;

enables the combining of land administration/georegulation information from different sources in

a coherent manner.

The following are outside the scope of this document:

interference with (national) land administration/georegulation laws that may have any legal

implications;

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 basic structure for standardization in the land

administration/georegulation domain. It defines a general schema that permits regulatory information

to be described. It also allows for the relationship to multiple parties and groups to be expressed

together with a referencing structure so that sourcing of all information systems may be maintained.

This document establishes the common elements and basic schema upon which more detailed schema

may be established. Other parts of ISO 19152 will address specific areas of the land administration

paradigm building upon the common core schema defined in document.
