Priority Assessment Method of Green Open Space (Case Study: Banjarbaru City)

Green open space planning in Indonesia is mostly based on its quantity requirement, not its effectivity to cool down the heated island cities. This study aimed to build a priority assessment method in determining green open space location based on characteristics of Banjarbaru City. GIS-based mapping analysis was executed from satellite imagery to determine land cover types, vegetation density (NDVI), and temperature humidity index (THI) as indicators. They were overlaid together with population density and land price. Scoring analysis was used to select the highest priority area to build new green open space. This method is also applicable to other tropical cities.
