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...

3 Dimensional data research for property valuation in the context of the LADM Valuation Information Model

Property valuation is a process that promotes sustainable development as it supports and forms several land management activities. Access to information on the legal, geometric, physical, locational and environmental characteristics of property units together with the economic indicators are required for an effective property valuation system...

Code list management supported through a controlled domain vocabulary

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...

3D Data for Better Property Value Estimation in the context of LADM Valuation Information Model

Property valuation is a process of estimating value of an immovable property. The legal, geometric, physical and environmental characteristics of the immovable property together with the economic indicators are taken into consideration during this process. Traditional cadastral systems only provide two-dimensional (2D) legal and geometric...

International Code List Management – The Case of Land Administration

Standardization reduces technical barriers to trade and foster dissemination of innovations. Within the domain of information technology, standardization enhances semantic interoperability of systems and services. In order to achieve the potential of standardization, IT solutions must be localized to adapt to local needs. To reduce localization...

The LADM Valuation Information Model based on INTERLIS

The geometric, legal, physical, economic, and environmental characteristics of property units are utilized in valuation activities. Property valuation registries and databases are supposed to record these characteristics in relation to property units that are subject to immovable property valuation. Moreover, the links between valuation...

Supporting Fiscal Aspect of Land Administration through an LADM-based Valuation Information Model

This paper presents an information system artifact for the fiscal aspect of land administration, a valuation information model for the specification of inventories or databases used in valuation for recurrently levied immovable property taxes. The information model is designed as an extension module of ISO 19152:2012 Land Administration Domain...

A Database Implementation of LADM Valuation Information Model in Turkish Case Study

A recently started joint activity under International Federation of Surveyors (FIG) Commission 9 (Valuation and the Management of Real Estate) and FIG Commission 7 (Cadastre and Land Management) has started development of an information model for the specification of valuation information maintained by public authorities especially for property...

Towards Turkish LADM valuation information model country profile

A recently established joint working group under International Federation of Surveyors (FIG) Commission 9 (Valuation and the Management of Real Estate) and FIG Commission 7 (Cadastre and Land Management) has started the development of an information model for the specification of valuation information maintained by public authorities especially...

A Knowledge Organization System for the Development of an ISO 19152:2012 LADM Valuation Module

The challenge to develop interactive information services for new domains is supported by Knowledge Organization Systems and Services (KOS), which model the underlying semantic structure of a domain through classification systems, thesauri, gazetteers, or ontologies. The ISO 19152:2012 Land Administration Domain Model (LADM) is an international...

Towards an International Data Standard for Immovable Property Valuation

Immovable property valuation is performed by public sector actors for several land management activities, such as property taxation, expropriation or compulsory purchase of land, land re-adjustment and land consolidation; and private sector actors perform valuation for purchase, real estate financing, investment analysis, and further property...
