Abstract
In recent decades, the adoption of geoinformation technologies has grown more crucial in determining the various characteristics that define the Earth’s environment. GIS tools have evolved significantly to planning for environmental and urban development. This research examined various geoprocessing approaches employed by the ArcGIS MODELBUILDER to decide whether a site is suitable for a slum relocation procedure. Three potential relocation sites for a slum in Cairo were examined using 12 different criteria. Five degrees of suitability have been included for sites assessment. Results were applied according to the score for each site and the final degree of suitability was recorded for decision support of slum relocation. Comparing the proposed sites, Site 3 showed the highest level of suitability for the relocation of slums, scoring 4.246 (84%), followed by sites 1 and 2 with scores of 3.99 (79.8%) and 3.43 (68.6%), after the weighted ratings for each element were determined.
