Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 19144-2 was prepared jointly by the Food and Agriculture Organization of the United Nations (UNFAO)
and Technical Committee ISO/TC 211, Geographic information/Geomatics under a cooperative agreement
between the two organizations.
ISO 19144 consists of the following parts, under the general title Geographic information — Classification systems:
— Part 1: Classification system structure
— Part 2: Land Cover Meta Language (LCML)
Introduction
Efficient assessment of land cover and the ability to monitor change are fundamental to sustainable management
of natural resources, environmental protection, food security and successful humanitarian programmes. Such
information is also required to help towards raising levels of nutrition, improving agricultural productivity,
enhancing the lives of rural populations and contributing to sustainable growth of the world economy. However,
in the past, policy-makers and planners have not had access to reliable and comparable land cover data, not
only for lower-income countries but also at the regional and global levels.
Access has been limited by two factors: Lack of mapping activities and lack of commonality between systems.
The solution has been to carry out separate regional mapping projects using national or regional land cover
classification systems. However, it has not been possible to compare or to exchange information between
current systems.
The aim of this part of ISO 19144 is to enable the comparison of information from existing classification systems
in a meaningful way without replacing them. The aim is to complement the development of future classification
systems that can offer more reliable collection methods for particular national or regional purposes by allowing
them to be described in a consistent manner.
A critical factor in implementing such global activities is the availability of a common, umbrella land cover
classification system structure. This then provides a reliable basis for interaction without replacing the
increasing number of national, regional and global land cover mapping and monitoring activities. This enables
comparisons of land cover classes to be made regardless of mapping scale, land cover type, data collection
method or geographic location.
Another critical factor is the availability of a common reference for land cover classification systems. This part of
ISO 19144 provides a metalanguage expressed as a UML model that allows different land cover classification
systems to be described.
This part of ISO 19144 establishes a metalanguage for a set

This part of ISO 19144 establishes a metalanguage for a set of objects and rules (language) to describe land
cover features based on physiognomy that can be part of different land cover legends (nomenclature). This
provides a framework for comparing different systems and nomenclatures such as Corine, Africover, Anderson
(USGS), Global Map and national systems without replacing them. This is not a description of a nomenclature
nor is it a description of a specific set of classes.
