Abstract
Decisions about the allocation of land typically involve the evaluation of multiple criteria according to several, often conflicting, objective. With the advent of GIS, we now have the opportunity for a more explicity reasoned environmental decision making process. However, GIS has been slow to develop decision support tools, more typically relying on procedures outside the GIS software. In this paper the issues of multi-criteria/multi- objective decision making are discussed, along with an exploration of a new set of decision support tools appropriate for the large data-handling needs of raster GIS. A case study is used to illustrate these tools as developed for the IDRISI geographic analysis software system
