Seacage site suitability maps

Seacage site suitability maps were produced using GIS. Multiple GIS layers were constructed based on suitability class criteria (see table below, taken from the CADS_TOOL manual), and overlaid to visualise areas that fulfilled all criteria. These areas in Barru Regency, South Sulawesi, are indicated by green coloration in the map of the area.
