An ideal situation for a country or region will be to have a spatial data infrastructure (SDI)containing the datasets and models necessary to support all the planning and decisionprocesses. Often, especially in developing countries, this is not the case. Can governments takegood and valid decisions in cases where the available SDI is not capable of having all thedatasets or models required for the decision? In order to approach this question we havedeveloped a decision support system called DISCUSS (decision information system forcommunity understanding of spatial scenarios). DISCUSS is a customised application underArcMap and uses a fuzzy logic methodology to incorporate the soft information from the expertsand the community into the decision process. The main objective of DISCUSS is to reduceuncertainty in the spatial distribution of decision impacts and at the same time support publicparticipation. The System and the maps that it produces are being tested in a case study withlong-term consequences for a large area of south-eastern Australia.
