The application of spatial analysis to cadastral zoning of urban areas: an example in the city of Madrid.

Abstract

Spatial Analysis has been used since the 1990s for hedonic cadastral models of urban areas in large cities. This research aims to apply spatial analysis to zoning a district in Madrid located in the central part of the city in order to estimate urban housing prices. In doing so, the necessary data have been gathered ? both vector and raster- as found on the official government website and private company websites. This was done firstly to analyse the characteristics and then for the objectives of the study because it is rather helpful to use these types of analyses based on vector and raster data along with interpolation methods that obtain regular structures and attempt to avoid the subjective component inherent to traditional procedures. The essence of the work consisted of studying the minimum parameters that influence housing appraisals to resolve the problem. Normally, cadastral appraisal work fulfils the Official Technical Regulations in each country considering a greater number of parameters and corrective coefficients. The importance of this work consisted of lowering and prioritising the number of basic parameters necessary to set urban housing prices. The conclusions section confirms a high likelihood of successfully reducing the number of parameters to achieve an appraisal value that is similar to the one obtained using official methods.
