Spatial decision-making for land valuation: a GIS and multicriteria analysis approach. A case study of Luweero town council.
Abstract
The process of assessing the characteristics of a given piece of land based on experience and
judgment is known as land valuation. The goal of land valuation is to determine a market value or
benefit value that is determined primarily by its location. This emphasizes the importance of spatial
factors in land valuation decision making. Many tangible and intangible land valuation factors
should be considered during the valuation process in order to make an accurate estimate of a land's
value. A sufficient estimation can be made by objectively analyzing a certain number of land
characteristics. In this research project, seven parameters were used to determine the market value
of a land: distance to schools, distance to roads, distance to police station, distance to roads,
distance to health facilities, land-use type, and distance to government buildings.
The shape files for each component were constructed using data supplied by the Uganda Bureau
of Statistics and others created by the researcher. In the ArcGIS setting, the weights established by
the questionnaire survey and the Analytical Hierarchical Process (AHP) approach were utilized to
classify the aforementioned maps. The final results revealed a stunning result regarding land
values. Eventually, the region was separated into land value classes and classified as extremely
low, low, moderate, high, and extremely high valued areas. It may be determined that the overall
area has a higher value since it is well equipped with infrastructure and other services. It may be
stated that this type of model would be quite useful in the land appraisal process. Furthermore, the
study advised that the model be enhanced with more parameters than the provided model.
