Abstract

The decision to refine the existing content and to extend the scope of Edition I of the ISO 19152:2012 Land Administration Domain Model (LADM) is a response to requests from the international Land Administration (LA) community. This response has to be formally organised in accordance with ISO guidelines. This begins with gathering feedback from ISO/TC 211 Member States on the need for updated and enhanced capabilities of the LADM. In addition, several proposals have been made to extend the scope of the LADM Edition I. After analysing the feedback received, it was proposed to develop the LADM Edition II as a multi-part standard: Part 1 — Generic conceptual model, Part 2 — Land registration, Part 3 — Marine georegulation, Part 4 — Valuation information, Part 5 — Spatial plan information and Part 6 — Implementation aspects. In other words, Edition I focuses on land tenure, while the design and development of Edition II is based on the inclusion of rights, restrictions and responsibilities (RRRs) concerning marine georegulation, valuation information, spatial plan information as well as LADM implementation. 3D representations are relevant for all parts.

This paper focuses on the design of the new structure of the second edition of the LADM and on the (operational) capabilities of this new edition in relation to the LA issues in Parts (standards addressing a specific part of the scope) and Packages (groups of conceptually close classes), with a particular attention to the requirements and design related decisions taken in the revision process. The parts 1, 2, 4 and 5 are the parts in which the authors are currently involved. Part 1 will be a high-level umbrella standard; Part 2 is largely based on LADM Edition I and focuses on land registration, with an enhanced support on the surveying functionality, including new subclasses of spatial unit, and extended 3D spatial profiles. Part 3 harmonises the description of RRRs and aligns land concepts with marine aspects from the marine domain based on the International Hydrographic Organisation (IHO) S121 Maritime Limits and Boundaries Product Specification. Part 4 deals with valuation information used and produced in the context of land administration, while Part 5 deals with spatial planning information and includes the planned use of the land (zoning), resulting in RRRs. Lastly, Part 6 is planned to be about implementation of the LADM and will be developed in close collaboration with the Open Geospatial Consortium (OGC).

Funding

Funding Information:
Authors wish to thank the International Federation of Surveyors (FIG) for its support of the development of the second edition of LADM. The authors further like to acknowledge contribution of the development team of ISO/TC 211 for their comprehensive and extensive reviews of the proposed versions of the different parts of second edition of the LADM. The input for this paper is (partially) based on all publications and events as the 3D Cadastre special issues in Computers, Environment and Urban Systems (Van Oosterom, 2013) and Land Use Policy (Van Oosterom et al. 2020); the book on Fig. 3D Cadastre Best Practices (FIG, 2018b), the Fig. 3D Cadastre Workshops (FIG, 2014, 2016, 2018c, 2021b), ISO/TC 211 LADM team meetings, FIG meetings, OGC meetings of the domain working group land administration) and builds on the contributed knowledge of all scientists and professionals who contributed to those publications and attended those events. Special thanks to project leader of Part 1 and 3 Chris Body, Australia, and to the main editor of Part 3, Douglas O'Brien, Canada, who also contributed to the development of the architecture of the LADM Edition II.
