The methodology begins with the collection of spatial data related to the analysis criteria. The information is publicly available and obtained through environmental and governmental institution portals. The data are organized, processed, and standardized. Subsequently, a literature review and expert consultation are conducted to validate the selected criteria and support the relative weighting process. Three weighting methods are applied: Equal Weights, Analytic Hierarchy Process (AHP), and Rank Reciprocal Weights (RRW). With the weights defined, a weighted overlay of the criteria is performed using map algebra, resulting in three cost surfaces. Dijkstra’s algorithm is then applied to each surface to trace the least-cost paths.
