The Land Administration Domain Model (LADM) Is Becoming to
an International Standard – the Proposal Passed Vote at the ISO TC 211
Meeting
Quebec City, Canada, 2-6 November 2009
In the beginning of 2008 FIG submitted a proposal to develop an
International Standard concerning the Land Administration Domain to the
Technical Committee 211 on Geographic Information of the International
Organisation for Standardisation (ISO/TC211). The proposal received a
positive vote from the TC211 member countries and a project team started to
work on the development of the standard. The proposal was based on many
years of discussions on this subject within FIG and from the input of
several workshops and from many experts in this field worldwide. A first
version of the LADM was presented at the FIG Congress in Munich in October
2006.
The International Standard intends to provide an abstract, conceptual
schema with five basic packages related to (1) parties (people and
organizations); (2) rights, responsibilities, and restrictions (ownership
rights); (3) spatial units (parcels, buildings and networks); (4) spatial
sources (surveying); and (5) spatial descriptions (geometry and topology).
It enables the combining of land administration information from different
sources in a coherent manner. The LADM can include informal and customary
rights. It should be noted that there can be no interference with (national)
land administration laws.
Within TC 211 many issues and comments have been discussed during several
meetings held with a project team composed of 21 delegates from 17
countries. The Chair of this team was Christiaan Lemmen on behalf of FIG and
editor was Harry Uitermark, also on behalf of FIG. Most developing countries
are not members of TC211. For this reason UN-HABITAT was represented in the
project team by Solomon Haile. A significant contribution to the development
of the standard has been provided by the research community of ITC and TU
Delft (especially Prof. Peter van Oosterom) from The Netherlands.
There was a positive vote at the 29th Plenary Meeting of ISO TC 211 in Quebec City in
November 2009 on forwarding the ISO 19152 Land Administration Domain Model
as a Draft International Standard (DIS). An Editing Committee is working now
on the DIS, which is expected to be available in March 2010. The final
International Standard is expected in 2011.
FIG expects this standard to be accepted and supported by a wide
community. It can then form the basis for software development and for data
exchange of land information. In this way the LADM can contribute in the
development of flexible land administration systems.
