Mapping Groundwater Potential Zone Based on Remote Sensing and GIS Using Analytical Hierarchy Process (AHP) in Tana Righu, West Sumba, Indonesia

This study aims to delineate groundwater potential zones in Tana Righu. Multiple thematic maps were prepared using RS and GIS techniques was assigned suitable weights on the Saaty’s scale. The of then normalized AHP technique. Ultimately, these integrated with a weighted overlay technique GIS. results showed that about 42% area has “moderate” potential; 35.86% “high” 28,82% ”low” potential. 3.57.1% “very high” 1.56.1% low” Overall, this provides more efficient approach mapping availability. are expected assist planning, management better utilization resources.
