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.
