Second edition of LADM published - and a special thanks
October 2025
The fifth part of the second edition of the Land Administration
Domain Model was recently published as ISO and CEN standard. The second
edition is a standard that defines land administration in a broad sense.
Drawing up these standards took a lot of effort, but the result is
definitely worth it. In addition to land tenure, marine georegulation,
valuation information, and spatial plan information are now also
included. The publication schedule is listed below.
The Social Tenure Domain Model is included in part 2. The next step
is to develop Part 6, ‘Implementation’, together with ISO and OGC.
The standard has been published by ISO and CEN, its development is an
initiative of FIG.
FIG publication no. 84 provides a comprehensive overview and
includes an extended version with a set of training materials.
The new edition of LADM will be presented during the
FIG
Joint Land Administration Conference to be held 3-5 November 2025,
Florianópolis, Santa Catarina, Brazil from 3 till 5 November 2025. The
13th LADM & 3D LA workshop is part of the program.
The publication of the new edition of LADM would not have been
possible without the support of the FIG Foundation, Kadaster
Netherlands, Delft University of Technology and Twente University (ITC).
The FIG Foundation has awarded
a grant
to Abdullah Kara, the editor of parts 1, 2, 4 and 5 of the LADM.
We are very grateful for this.
We would like to thank our many colleagues from many countries for
their contributions.
Peter van Oosterom, Abdullah Kara and Christiaan Lemmen
A special thanks to Christiaan (Chrit) Lemmen, FIG Honorary Member
Together with this update on LADM, Christiaan (Chrit) Lemmen has
announced that he will step down as FIG representative in ISO/TC 211.
 |
The work on the standard was started with his Ph.D thesis.
He continued working on LADM and has been one of the the main
drivers behind the ISO standard and the cooperation with ISO.
Dutch Kadaster has supported Chrit to represent FIG in ISO/TC
211and in the work to develop the LADM standard.
Over the past 20 years Chrit has played acentral role in FIG.
Apart from the development of the LADM standard he has been
involved in the deveopment of pro-poor Land Administration tools
and he has served as the director of OICRF from 2010 to 2022
where he handed over to Eva-Maria Unger. Chrit is highly
respected worldwide and within FIG, and he has attended numerous
FIG events, both Congresses, Working Weeks, Commission 7 events
and other expert groups. |
His many international FIG engagements led to the appointment of
Chrit as Honorary Member of FIG at the General Assembly 2015. Even
though Chrit retired from Kadaster in 2021 he continued tirelessly the
work on the 2nd edition of the LADM standard together with Abdullah Kara
and Peter van Oosterom. The FIG publication 84 that gives an overview of
the development of the LADM standard is just the latest example of
Chrits hard work and engagement.

Member of FIG. Certificate and pin is presented by FIG President Chryssy

It is understandable that Chrit has now announced that he will step
down from this last official post in FIG after having been retired for
several years. Hopefully he will still be available for good advise,
insightful comments and always positive encourgements.
FIG wants to thank Chrit wholeheartedly for his amazing, constant,
and absolutely outstanding work over these many years. He has really
been the driver and central in many activities, especially to LADM and
to what it has become today. And a personal thanks for many good talks
(and laughs) over the years, that were both fun, inspiring and soothing.
Thanks for everything Chrit!
