Optimization of land valuation factors by GIS SPSS
Nisanci, Recep ... [et al.]
This study aims that the land-value maps are produced with less number of factors by limiting the factors affecting the value of land. In order to make adequate value estimation for a land parcel, there are many tangible and intangible land valuation factors that should be taken into account during the valuation process. The determination and classification of these valuation factors are difficult, because the characteristics of these factors can be objective and subjective, changing according to personns desires. Indeed, the number of land valuation factors cannot be limited. But, it can be limited depending on the aim and scale of the work. In other words, a land value map produced in a less accuracy level with less number of factors or with the factors changing according to the personns desire can be demanded. In this study, a land value map based on nominal valuation method is produced for Trabzon province by using 20 factors with Geographic Information Systems (GIS). SPSS statistical software is used to make a regression analysis between nominal and current values. The highest explanation value calculated in the model using 20 factors is R-square = 0.861 and it is obtained from the cubic curve. R-square = 0.734 when 8 factor is used for calculation.
