Urban Farm DB summary

In Seoul, South Korea, the suitability of urban rooftop greenhouses (RGs) was analyzed by combining the Analytical Hierarchy Process (AHP) and Geographic Information Systems (GIS). Location suitability factors were derived through expert consultations, and AHP was used to calculate factor weights. The highest weight for RG location factors was benefit (0.1782), followed by officially assessed land prices (0.0913) and supermarket density (0.0802). Analysis linking these results with spatial data revealed that Gangseo-gu had relatively high location suitability scores.
