The Land Administration Domain Model is at Draft
International Stage
The Land Administration Domain Model (LADM) has been published as a Draft
International Standard by the International Organization for Standardization
(ISO), as ISO 19152. P-Members of ISO/TC 211, Geographic
Information/Geomatics, can comment on the draft and are in the position to
vote on continuation of the development. Liaisons to ISO/TC 211, such as
FIG, can also comment on the draft. The deadline for voting and comments is
June 20th, 2011. The Draft International Standard has also been submitted to
CEN/TC 287, the European Committee for Standardization member body, for a
parallel five months’ inquiry.
The development of this standard is an initiative from FIG. It is a
comprehensive, extensive, formal process with a continuous review and a
continuous, creative approach to find common denominators in land
administration systems and included data sets.
The draft standard covers basic information related to components of land
administration (including water and elements above and below the earth). It
includes agreements on data about administrative and spatial units, land
rights in a broad sense and source documents (e.g. deeds or surveys). The
rights may include real and personal rights as well as customary and
informal rights. Restrictions and responsibilities can be represented in a
flexible way.
LADM describes the data contents of land administration in general, based
on a practical approach. The roots are in FIG’s Cadastre 2014.
Implementation can be performed in a flexible way; the standard can be
extended and adapted to local situations. External links to other data
bases, e.g. addresses, are included. The draft standard defines the core
issues in land administration. The LADM is a conceptual schema organised in
packages: (1) Party Package, (2) Administrative Package and (3) Spatial Unit
Package. Existing standards have been re-used, particularly from the ISO
19100 series from ISO/TC 211. It also includes the standard, ISO 19156,
Geographic information – Observations and Measurements, which is under
development in ISO/TC 211.
LADM can be a basis for combining data from different Land Administration
Systems. The Draft International Standard includes informative example cases
with people and land relationships demonstrating the flexibility of the
draft standard. Further, the relationships with the INSPIRE (Infrastructure
for Spatial Information in the European Community) Cadastral Parcels model
and LPIS (Land Parcel Information System – this is a part of the Integrated
Administration and Control System established by the European Union Member
states) are described in annexes. 3D Cadastres are covered in such a way
that these seamlessly integrate with exiting 2D registrations.
Several reviews have been performed by the Editorial Committee. Formal
comments as provided by the ISO/TC 211 member bodies have been discussed and
processed. The Editorial Committee’s members are from nine countries and
from UN HABITAT and European Commission.
Those efforts resulted in the Draft International Standard. This is a
milestone and an achievement where FIG may be proud of. Comment can be
provided via the national member bodies of ISO. If anyone would like to
comment on the draft through FIG, please contact us at
