Joint ISO/TC211 and OGC Revision of the LADM: Valuation Information, Spatial Planning Information, SDG Land Indicators, Refined Survey Model, Links to BIM, Support of LA Processes, Technical Encodings, and Much More on Their Way!

ISO standards, which are actually being applied, are subject to periodic revision, typically in a 6 to 10-year cycle. A UN-GGIM Meeting of the Expert Group on Land Administration and Management was held on 14-15 March 2017, in Delft and the main conclusion was that the revision of LADM was indeed needed in order to provide better tools to improve tenure security and better land and property rights for all. It was also noted that land administration is a rather complex domain, and thus the revision will involve many stakeholders, namely: ISO, FIG, OGC, UN-Habitat, UN-GGIM, World bank, GLTN (Global Land Tool Network), IHO, RICS, etc..
Further goals of the revision include: providing reliable Land Administration Indicators for the Sustainable Development Goals (SDG), developing standard(s) supporting a Fit-for-Purpose approach, paying attention to implementations and tools (not just conceptual model), and inclusion of valuation information (which might help to define/support the Fit-for-Purpose approach). In order to prepare the LADM revision, two workshops were organized: 16-17 March 2017 (Delft) and 11-13 April 2018 (Zagreb), with experts involved in the development
of the initial version of LADM and representatives of all the mentioned stakeholders. For the purpose of the revision, it is important to analyze and compare currently operational and proposed country profiles and their implementations of the first version of LADM, ISO 19152:2012.
This paper gives an overview of the status of developments and the related proposals.
