This app maps the location of swimming pools across the island of Rhodes for 2017 and 2024, identified using AI object detection on satellite imagery and orthophoto maps. It lets users compare the two time periods side by side, revealing how pool density and distribution have evolved across the island over seven years. By combining computer vision with historical and recent imagery, the tool supports both municipal tax-compliance monitoring and water-resource management on an island already facing seasonal water scarcity, giving planners a clear, evidence-based picture of unregistered infrastructure and its pressure on local water supply.
