Mass Valuation Using Quantified Spatial Characteristics of Cadastral Parcels

Each modern state needs to have a real estate valuation system for purposes of: fair real estate taxation, as a support to the real estate market, for better management of rural or urban environment or any other purpose. This enables a mass valuation system by systematic valuation of groups of real estate units performed on a certain date with the help of standard procedures and statistical analysis. In order to be able to valuate real property its size and value-per-size factor are required. The product of the two multiplied by, for instance, the tax rate yields the amount of tax to be paid, but can also be used for other purposes. As opposed to the tax rate which is defined by legislative acts and the size which can be explicitly quantified (calculated) from its geometry, the value-per-size of real property must be determined based on a predefined set of rules and criteria. Generally, the more rules and criteria included, the more fairly the value can determined. Furthermore, for this value to be as fair as possible, the rules and criteria need to be defined and tested for the entire jurisdiction affected. Real property can generally be seen as land, buildings, and what-ever is attached or affixed to the land. In this research we limit our-selves to land i.e. a part of it defined by a cadastral parcel. Besides the size which is defined by its area, there are other characteristics of a cadastral parcel which explicitly and unambiguously define it. No matter what its purpose may be, the three spatial characteristics which directly influence the value of a piece of land are its azimuth, slope and shape compactness. In this paper we first give a theoretical background for the method for automatic quantification of the mentioned three characteristics, provided cadastral and DTM databases are available in digital form and managed using spatial database management systems (SDBMS) technology. The shape compactness of cadastral parcel is calculated using its area and perimeter. Slope and azimuth are calculated by spatially intersecting triangles from the DTM with the shape of cadastral parcel. Since we wanted a distinct value for the slope and azimuth of each parcel, ’ per parcel’ averages are calculated using the weighted mean of ’ per intersection’ values of slope and azimuth. The area of intersection was used as weight. Finally, a description of a test system based on presented method and implemented on top of Oracle10g SDBMS is given. Within the research a sample DTM and cadastral database have been loaded into the system, and response times to queries for a single cadastral parcel and for a set of 5100 parcels indicate that such a system should be able to function in real world conditions.
