Geographic Information Systems (GIS) are designed for the acquisition, management, analysis and display of georeferenced data. As such they have clear implications for informing the spatial decision making process. Subsequently, recent developments in GIS software and in the conceptual basis for decision making have led to dramatic improvements in the capabilities of GIS for resource allocation. These developments are reviewed through an examination of procedures for Multi-Criteria and Multi-Objective land allocation in GIS. Special emphasis is given to the problems of incorporating subjective expertise in the context of participatory decision making; the expression of uncertainty in establishing the relationship between evidence and the decision to be made; procedures for the aggregation of evidence in the presence of varying degrees of tradeoff between criteria; and procedures for conflict resolution and conflict avoidance in cases of multiple objective decision problems.
