Abstract:

Property valuation is the process of estimating value of immovable properties, at a specific time, using objective criteria. The valuation process, which is carried out by taking into account the legal, spatial, physical and environmental characteristics of properties together with economic factors, is one of the basic elements of the value component of the Land Administration. It is expected from an effective land administration to create inventories and information management systems in order to compile and record used and produced data in property valuation. Although international standards and data models containing information about the characteristics of properties required in the valuation processes have been developed in addition to international standards that offer formal semantics and technical specifications regarding property valuation processes, there are no guiding references on property valuation information management. This thesis focuses on the development of an international property valuation data model within the scope of land administration, and the implementation and testing of the developed model. In order to achieve these goals, initially by making use of the questionnaire survey conducted within the International Association of Measurers (FIG), literature researches, expert opinions, and especially the existing international standards; a conceptual valuation data model has been developed that allows three-dimensional (3D) and temporal data management, as a module of the International Organization for Standardization (ISO) 19152:2012 Land Administration Domain Model (LADM). The data model is designed to enable recording and managing the parties involved in the valuation processes, valuation objects and their required characteristics, valuation procedures, valuation performance analysis and quality control processes. The model provides a common basis for government to direct the development of local or national inventories, databases and information management systems and for the private sector to develop information technology products. The operability of the developed model is evaluated with an implementation in terms of the valuation processes carried out to determine tax values of properties. The developed data model has been accepted by the scientific community and ISO/TC 211 standardization committee, and it was decided to include the model in the ISO LADM Edition II as a separate standard, which is the international standard for administration.
