    A Comparison of Housing Prices Calculated Through Floor Premium and Housing Prices Calculated Through Valuation Reports
    (Ieee, 2017) Alas, Birol; Harita ve Kadastro / Survey and Cadastre
    When it comes to housing pricing, particularly when housing estates are concerned, determining price differences based on varying features is an important aspect. In practice, floor premiums are calculated via a selection of methods and reflected in prices. In this study, parameters thought to influence housing prices have been weighted to find out the prices of all available apartments in a housing estate, the total cost of the project being unchanged, and these prices have been compared to those derived through evaluation reports. Analyses show that there is a significant difference between the prices of apartments when calculated through floor premiums and those of apartments when established as a result of an evaluation report.

    Impact of pipelines on land use in rural areas in Turkey
    (Springer international Publishing Ag, 2016) Alas, Birol; Harita ve Kadastro / Survey and Cadastre
    This paper examines whether the parcelization of land through easement as a result of the construction of pipelines in rural areas in Turkey has any negative effects on productive land use. The current legislation in Turkey does not allow the division of land in most rural areas into parcels smaller than 5000 m(2). Therefore, the smallest parcel that can be productively used was considered as 5000 m(2). On the basis of the analysis of the data pertaining to the easement rights having two different widths and collected from three different regions having different parcel sizes, the research aims to find out the number of parcels with an area less than 5000 m(2) (excluding the easement) that were created by the construction of pipelines and to investigate whether a significant number of areas less than 5000 m(2) remain. This study also demonstrates a method that can be used in studies on this subject according to the various parcel sizes that were created by the allotment of parcels due to the easement of the construction of pipelines.

    A multilevel analysis of housing submarkets defined by the municipal boundaries and by the street connections in the metropolitan area: Istanbul
    (Springer, 2020) Alas, Birol; Harita ve Kadastro / Survey and Cadastre
    This paper focuses on the performance of the multilevel model within the metropolitan area and explores the submarkets of housing prices at the metropolitan level. In addition to the district and neighborhood segmentation within municipal boundaries, areas using the same street for transportation are segmented into submarkets to reveal the effect of the street on price. A fully-random multilevel model is used for finding out a correlation between the prices of housing units and their location. This study compares four submarket modeling strategies based on the data on housing sale transactions in Istanbul. The first model is a simple hedonic model using ordinary least squares and taken as a city-wide 'benchmark' model. Three different types of multilevel models are used for models 2,3 and 4. Model 2 and model 3 use district and neighborhood boundaries, which are respectively predefined as spatial divisions. Model 4 represents the geographically smaller areas that use the same street for transportation. The results reveal that multilevel models with smaller spatial units of geography are capable of improving predictive performance in determining dwelling prices in the metropolitan area and that the sub-regional spatial units that use the same street for transportation have an effect on the spatial dimension of submarket boundaries.

    THE USE OF GEOGRAPHY MARKUP LANGUAGE IN TURKEY FOR SPATIAL DATA
    (int Scientific Conference Sgem, 2011) Alas, Birol; Harita ve Kadastro / Survey and Cadastre
    This paper evaluates the usage of the Geographic Markup Language (GML) in Turkey and essential subjects of the interoperability concept in Turkey for the future. Geography Markup Language-GML was developed by Open GIS Consortium-OGC. OGC presented GM L based upon the technology of Extensible Markup Language-XML developed by World Wide Web Consortium-W3C. It was planned to constitute a layer for land registry and cadastral data at studies of INSPIRE (Infrastructure for Spatial Information in Europe) that adopted OGC standards. Digital land registry and cadastral sheets in Turkey have to be encoded according to an application schema prepared using GML schemas developed with XML technology that is among the information technology tools supporting the open source and interoperability. In particular, it focuses on determining the usage of GML in Turkey for Land registry and cadastral data and what measures must be taken to deal with the difficulty that will be opposed in the future.
