Two New Publications: The Land Administration Domain Model - an overview, and LADM in the Classroom

March 2025

In 2012, the Land Administration Domain Model (LADM) was approved as an official ISO standard. The LADM is a conceptual information model. It describes and structures the core of a land administration: information about people, about land and about people to land relationships.

LADM supports the establishment of a common view on land administration across stakeholders involved. It stimulates the development of software applications and accelerates the implementation of proper land administration systems in support of sustainable development. It supports interoperability in land administration. This is a real need because land administration is mostly implemented under distributed mandates with many stakeholders. The LADM provides an internationally recognised model and vocabulary, which provide a solid foundation for the development process. It covers the ‘information-related’ components of land administration, including those over water and land, and elements above and below the surface of the earth. This means in practice that the representation of all tenure types is being supported – even when overlapping – and that 3D land administration can be developed. There are now implementations of LADM all over the world.


The Land Administration Domain Model - An Overview
FIG Publication 84 - FIG Guide

This publication gives an overview of LADM. The publication is intended for anyone wishing to learn more about LADM: why is it needed, how is it designed, what is it and what are the benefits. This overview publication has an extended version titled ‘LADM in the Classroom’ with a focus to training and higher education.

LADM in the Classroom
Extended version

This book introduces the reader to the Land Administration Domain Model (LADM) through examples. It starts by giving the reader an overview of core LADM concepts then proceeds to illustrate how data about different people-to-land relationships can be organized using LADM. Each example represents a scenario that can be encountered in a Land Administration System. The scenarios used in examples are derived from the Land Administration System of the hypothetical town of Watteriver together with its surrounding rural areas. Each case, representing a particular scenario, is presented both conceptually and using a simplified representation of a database in which data are stored concretely. A demonstration dataset, accompanying GIS project, and reusable slides are available online - details in the book.
