Description
Summary:This paper introduces a streamlined geographic information system (GIS) framework for assessing the relative importance of different alternatives based on criteria in land suitability for urban development. Five criteria are considered in this proposed work based on factors. Expert opinions are used to assign weights to each criterion based on their relative significance. The proposed work constructs a hierarchical structure that incorporates study area criteria, employing the Analytic Hierarchy Process (AHP) method to ensure a uniform scaling of weights. To finalize the rankings, the criteria weights are incorporated into the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method, requiring four alternatives for assessment. GIS is employed to perform multicriteria overlay analysis (MCDA), resulting in the identification of four distinct land suitability categories: ’not suitable area,’ ’suitable area,’ ’more suitable area,’ and ’most suitable area’. This final land suitability map is generated assisting in well-informed decisions regarding optimal land use.
