An Empirical Study Investigating the Relationship between Land Prices and Urban Geometry

Land prices are among the most important parameters of urbanization and have been an important subject of urban geography studies for many years. The relationship between urban geography and land prices was examined in the first established models, which had linear and static structures. In these models, which have a radial form, cities are considered to be commercial centers. However, since the 20th century, it has been accepted that cities have structures without obvious order, consisting of many subsystems related to political, social, and economic life and space. This irregular structure that repeats itself independent of scale has a fractal geometry. Developments in the field of geographic information systems in the last 30 years have provided great convenience in analyzing the structure of cities with fractal dimensions. The geometric shapes of buildings, streets, and blocks that create the physical city form at the same time constitute the urban geometry. This study, which aims to investigate the spatial relationship between urban geometry and land prices, examines the relationship between the fractal dimension values of buildings, streets, blocks, and land prices and whether the factors of population and distance to the center have an impact on this relationship by using geostatistical methods. In this context, the fractal dimension values of urban geometry components were calculated separately in the study area, consisting of 65 neighborhoods. A two-step cluster analysis was used to determine how these obtained fractal values are dispersed geographically within the study area. By measuring the success of clustering through the independent samples t-test, it was decided which data would be used in the regression model in which the relationship between urban geometry and land prices would be established. By using exploratory factor analysis, intercorrelated data to be used in the regression model were eliminated. According to the results of the multivariate regression model, it was revealed that there was a directly proportional relationship between the fractal dimension values of building-block geometry and land prices, and an inversely proportional relationship between the fractal dimension values of street geometry and land prices

Investigation Of the Relationship Between Property Geometry and Urbanization By Calculating Fractal Dimension Values: A Case Study Of Sivas

1950’lerin ikinci yarısından itibaren planlamada sistem yaklaşımı yaygın olarak kullanılmaya başlanmıştır. Bu sayede, kentlerin karmaşık yapısı, kaos ve karmaşıklık teorileri ile modellenebilmektedir. Kentin fiziksel yapısı, ölçekten bağımsız, düzensiz ve kendini tekrar eden bir yapıya sahip olan fraktaller ile analiz edilebilir. Bu makalenin amacı, kent çeperlerindeki mülkiyet geometrisi ile kentleşme arasındaki ilişkinin araştırılmasıdır. Bu bağlamda, Sivas il merkezinin kenarında yer alan 10 mahalledeki kadastro parsellerinin ve yolların fraktal boyut değerleri, sırasıyla 1,79 ve 1,32 olarak hesaplanmış ve nüfus verileri ile ilişkileri araştırılmıştır.After the second half of 1950s, system approach has been widely used in planning studies. In this way, complex structure of cities can be modelled with chaos and complexity theories. Urban physical structure can be analyzed with fractals of which characteristics contain scale-independence, irregularity and self-similarity. The main purpose of this paper is to investigate the relationship between ownership geometry and urbanization. In this context, fractal dimension of cadastral parcels and streets were executed as (respectively) 1.79 and 1.32 for ten districts located in the fringes of the Sivas downtown area and looked for their relationship with population
