Design of the new structure and capabilities of LADM edition II including 3D aspects

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...

LADM's Links with International Standards, Guidelines and Frameworks

The first edition of the Land Administration Domain Model (LADM) has been available as a formal International Standard since the 1st of December 2012, published as ISO 19152:2012. It is based on / makes use of a number of standards, in particular those published by ISO/TC 211 and, of course, other committees. In addition, non-ISO standards and...

Requirements Based Design of the LADM Edition II

This paper examines the requirements based design of the LADM Edition II. The requirements are the starting point for the Abstract Test Suite (ATS, Annex A in an ISO standard). The requirements/ATS can be used to assess if a given LADM country profile with a specific application schema is conformant with the LADM standard. The requirements are a...

Land Administration Domain Model OGC Standards Working Group

In February 2019 the OGC White Paper on Land Administration is published. This White Paper provides an overview of the land administration domain and relevant developments. It also proposes necessary actions for the design and development of an implementation standards. The document includes an overview of needs and requirements as earlier...

Formalisation of code lists and their values – The case of ISO 19152 Land Administration Domain Model

A code list in Unified Modeling Language (UML), a simple list of values without any structure, can be employed as a simple data type to further capture the semantics of a domain. The code list values as used in international standards (e.g. ISO and OGC) are generally presented without definition, reference to the source of a definition, multi...

3D Registration of Apartment Rights Using BIM/IFC: Comparing the Cases of the Netherlands, Saudi Arabia, and Turkey

Τhe built environment has a vast and ever-growing number of complex and multi-layered buildings and other structures. The number of those is growing because of the increasing pressure on the limited space in cities. It is important to note that different professional sectors are involved in the realization of a new building. These sectors are...

The LADM Valuation Information Model and its application to the Turkey case

Spatial data in a Land Administration (LA) establish a fundamental geospatial data theme (see UN GGIM, 2018) and the integrated geospatial information framework for any Spatial Data Infrastructure (SDI). Domain-specific standards, an integral component of the SDI, play an essential role to represent the semantics of domains, specify links...

The scope of LADM revision is shaping-up

After two LADM workshops (Delft, March 2017 and Zagreb, April 2018) and three ISO TC211 meetings, where also LADM revision meetings took place (Copenhagen, May 2018, Wuhan, November 2018 and Maribor, June 2019) there is consensus growing towards the new scope of the standard. This new scope is described in this paper, and it is no exaggeration...
