“…The key benefit of the database application is to spot discrepancies and duplicate properties in the conceptual model and also missing or misspecified relationships between classes (Kara et al, 2021). One of the practices of LADM is to realize technical models for implementation using the INTERLIS conceptual model language and compare its performance with the approach taken in this study.…”

“…The model produced in the study (Alattas et al., 2021) on the 3D representation of the building unit's subdivision procedures using the LADM conceptual model was tested with instance‐level diagrams for different ownership levels. In the study that proposes a valuation and tax package for Turkey's country profile, instance‐level diagrams are used to determine whether the tax value in the case of rural land parcels is represented in the profile (Kara et al., 2018). Investigating the usability of the conceptual model provided by the LADM standard for indoor navigation in combination with IndoorGML, the study tests whether the combined model can represent the RRRs of parties on spatial units with instance‐level diagrams (Alattas et al., 2017).…”

“…In the study demonstrating the compatibility between the Indonesia country profile and the spatial planning information package (Indrajit et al., 2021), the proposed conceptual model has been primarily utilized for the three‐dimensional visualization application of spatial plans. There are also studies using the object‐oriented language Interoperable Land Information System (INTERLIS) to check the conceptual model before it is translated into a physical model (Baron et al., 2018; Kalogianni et al., 2017; Kara et al., 2021). INTERLIS schemas are a modeling language that defines an XML‐based data exchange format that can be directly processed by a computer, is automatically system‐independent, and allows for fully automated quality control (Steudler et al., 2015).…”

Spatial planning plays a crucial role in shaping the future of urban development and land administration. While land registration information is necessary for spatial planning processes, it is also probable that changes in land registration data occur in line with spatial plan decisions. Development of the Land Administration Domain Model (LADM) Edition II It also aimed to extend its existing conceptual model with spatial plan data, considering the close connection between the two systems. The study aims to design a conceptual model for Turkey's spatial planning system within the LADM Turkey country profile context. This article researches the capability of the proposed conceptual model for representing spatial planning data with instance‐level diagrams and the implementation opportunities of a technical model. To demonstrate the functionality of the proposed model, the zoning status certificate, which contains spatial plan and land registration data and is provided to inform about the legal conditions before development, is chosen as the mission. The results show that the LADM Turkey country profile extended with spatial planning system data can represent spatial plan data and be implemented in a technical model to support land administration applications.

“…Furthermore, many publications focusing on 3D cadaster, land administration and taxation point out to the new possibilities for real estate valuation using the benefits of BIM technologies, especially through application and/or extension of land administration domain model (LADM) as an international standard for land administration (Atazadeh et al, 2017a, Atazadeh et al, 2017b, Isikdag et al, 2014, Kara et al, 2021a, Kara et al, 2021b, Kara et al, 2020, Isikdag et al, 2015, Ying et al, 2017, Guntel and Aydinoglu, 2021, Aien, 2013, Li et al, 2016, Paasch and Paulsson, 2021, Wu et al, 2021, Einali et al, 2022, Atazadeh et al, 2016, (FIG), 2018, Kara et al, 2022, Radulovi c et al, 2017, Almeida et al, 2013.…”

PurposeBuilding information modeling (BIM) is a striking development in the architecture, engineering and construction (AEC) industry, which provides in-depth information on different stages of the building lifecycle. Real estate valuation, as a fully interconnected field with the AEC industry, can benefit from 3D technical achievements in BIM technologies. Some studies have attempted to use BIM for real estate valuation procedures. However, there is still a limited understanding of appropriate mechanisms to utilize BIM for valuation purposes and the consequent impact that BIM can have on decreasing the existing uncertainties in the valuation methods. Therefore, the paper aims to analyze the literature on BIM for real estate valuation practices.Design/methodology/approachThis paper presents a systematic review to analyze existing utilizations of BIM for real estate valuation practices, discovers the challenges, limitations and gaps of the current applications and presents potential domains for future investigations. Research was conducted on the Web of Science, Scopus and Google Scholar databases to find relevant references that could contribute to the study. A total of 52 publications including journal papers, conference papers and proceedings, book chapters and PhD and master's theses were identified and thoroughly reviewed. There was no limitation on the starting date of research, but the end date was May 2022.FindingsFour domains of application have been identified: (1) developing machine learning-based valuation models using the variables that could directly be captured through BIM and industry foundation classes (IFC) data instances of building objects and their attributes; (2) evaluating the capacity of 3D factors extractable from BIM and 3D GIS in increasing the accuracy of existing valuation models; (3) employing BIM for accurate estimation of components of cost approach-based valuation practices; and (4) extraction of useful visual features for real estate valuation from BIM representations instead of 2D images through deep learning and computer vision.Originality/valueThis paper contributes to research efforts on utilization of 3D modeling in real estate valuation practices. In this regard, this paper presents a broad overview of the current applications of BIM for valuation procedures and provides potential ways forward for future investigations.

“…Since, most of the building rating systems such as LEED v4.1, give credit for direct access to the view (U.S. Green Building Council, 2020). Additionally, to evaluate goodwill, creating a three-dimensional (3D) urban model is needed since valuation practices today also require 3D property and environmental data (Kara et al, 2021). Therefore, BIM and GIS information is needed to combine for evaluating building and built environment relationships.…”

Abstract. Visibility is a significant parameter for defining, developing, and evaluating space in the AEC (Architecture, Engineering, and Construction) Industry. Therefore, visibility is considered when designing visually comfortable buildings. Visibility is also a significant parameter in building appraisal. Therefore, in this study, visibility was examined through 3-dimensional (3D) isovists, which are thought to represent the human perception of vision. Visibility was examined regarding spatial openness and mathematically calculated “visual openness indexes” were developed for building valuation. The analysis area was selected in Istanbul, and the urban model was created by using Geographic Information System (GIS) data in Building Information Modelling (BIM) software. Due to, economic reasons affecting different stakeholders in building valuation, it is necessary to create an accurate urban model. For this reason, in the study, the process of obtaining current and accurate GIS data covering the world from open sources is preferred. Then, the process of correctly transferring GIS data to BIM is explained. A sufficient urban model for analysis is created. To calculate the openness indexes, the dormitory in the Golden Horn was modelled in BIM, and different rooms' openness indexes were calculated. Some solutions have been presented to ensure the modelling process with large file sizes and in the calculation of visibility factors. To allow different AEC stakeholders to calculate these indexes, modelling, and calculation is done within BIM. Eventually, it was calculated how much the building users cognitively perceive the openness of the view, and a mathematical comparison of the different rooms' openness indexes was provided.
