LADM Valuation Information Model Compliant Prototype for Visualisation and Dissemination of 3D Valuation Units and Groups

Kara, Abdullah (author), van Oosterom, Peter (author), Kathmann, Ruud (author), Ilgar, Azer (author), Lemmen, Christiaan (author)

The interest in using 3D data in property valuation has been increasing during the last decade. The usage of 3D data models in valuation can be basically grouped in two main categories: (a) supporting mathematical models with variables produced through 3D analyses (e.g. view) in order to better estimate the values of properties and (b) consuming...

How to exploit BIM/IFC for 3D registration of ownership rights in multi-storey buildings: an evidence from Turkey

Guler, Dogus (author), van Oosterom, P.J.M. (author), Yomralioglu, Tahsin (author)

The condominium rights, which is a special ownership type that can only exist in the buildings that have an occupancy permit, are needed to be examined and depicted as three-dimensional (3D) in order to prevent misinterpretations and disputes regarding Rights, Restrictions, and Responsibilities (RRRs). This paper, therefore, aims to provide...

Code list management supported through a controlled domain vocabulary

Stubkjær, Erik (author), Gruler, Hans-Christoph (author), Simmons, Scott (author), Çağdaş, Volkan (author)

Standards like the ISO 19152:2012 Land Administration Domain Model (LADM) basically specifies classes and the relations among them. However, this methodology cannot catch the richness of variations of the domain, and therefore code lists are introduced as a supplement. In fact, the LADM mentions a number of code lists for each of the packages of...
