GIS-Based Model for Land Appraisal in Palestine

Abstract

The intention for land ownership in Palestine has fo increased in an accelerated way. The limited number of m available selling lands distributed in a wide spatial range Ad causes conflicts in determining proper and fair prices lo and value estimates. However, the estimates of value for of land appraisals are difficult because of varying factors pr affecting the evaluation. Here, the factors can be tra classified based on the market situation, economic ac activities in the region, political (such as land to classifications according to Oslo agreements between ph Palestinians and Israel, legal factors (type ownership), to and the parcel related factors (position, area, shape, fa topography, usability … etc.). The data available from pr various sources in GIS formats made it possible to solve Fu the complexity of land appraisal in a system by applying pr the most common values in GIS modeling methods. A an study area (a cadastral block) was selected. Historical Co data about land deals from the official and private pe sectors were collected. Afterward, spatial information Al was collected, including different land classifications, em land uses, and parcel data. The different factors were pr used as a weight for input. Where the chronicle data were to used to solve the least squares problem to optimize a re parameter related to each factor. Then the weight and parameters were used in a GIS model to calculate an In estimated value for each block parcel. Finally, the results or were validated with a tolerance of less than 2% of the est real deals.
