The first five parts of LADM Edition II have been published as ISO standards now

The Land Administration Domain Model (LADM), originally published as ISO 19152:2012, has undergone a systematic revision in response to demands from domain experts in land administration. As of 2025, the first five parts of the second edition of LADM have been published as ISO standards. This milestone marks a major step forward in providing modular, extensible, and internationally harmonised frameworks for the modelling of land administration systems. The newly published parts include Part 1 – Generic conceptual model, Part 2 – Land registration, Part 3 – Marine georegulation, Part 4 – Valuation information and Part 5 – Spatial plan information. Each part addresses a distinct aspect of land administration while remaining interconnected through a shared conceptual foundation. This paper will focus on the recent developments on LADM Edition II, namely publication of first five parts of LADM Edition II and introduce each published parts briefly. Together, these five parts significantly enhance the usability and relevance of the LADM standard across a broad spectrum of applications, from cadastral data management and urban planning to property valuation and marine cadastre. They provide a foundation for the development of digital land administration ecosystems, improve the quality and comparability of land-related data, and support international efforts to achieve Sustainable Development Goals (SDGs). The modularisation of the standard also allows countries and organizations to implement the parts, depending on their specific needs and capacities, while still ensuring semantic consistency. The publication of the first five parts of LADM Edition II represents not only technical advancement but also a strategic opportunity for countries to modernise their land administration infrastructure in alignment with international best practices. It opens new pathways for integration between cadastral, marine, valuation, and spatial plan systems, thereby improving land governance, reducing disputes, and enabling data-driven policy development. The paper includes an overview the most important changes in the new edition compared to the edition published in 2012.
