GIS-based landscape suitability analysis is a useful approach in the practices of urban design, planning, and management, especially for developing future land use, which includes the identification of land suitable for green infrastructure protection. We explored applying a multi-criteria decision analysis through GIS-based suitability tools to create a combined criteria map for developing a green infrastructure protection plan in Bandung Basin Region, Indonesia. We used two overlay techniques, the Weighted Sum Overlay and the Fuzzy Overlay. Both approaches aided the land suitability identification process for developing a green infrastructure plan in the region based on proposed objectives. Results showed that both cities of the region were predominantly built areas while the other three regencies were mostly vegetated open space, which suggested that the outer urban areas offered more opportunities to develop a green infrastructure protection plan. We also identified the key issues for future improvement of the overlay techniques application to help inform the planning and design process.
