Geo-BI provides an efficient tool for browsing and storing very large spatio-temporal databases. However, the process for evaluation and selection of the optimal decision in Geo-BI is very complex. Hence, the Multi- Criteria Decision Making (MCDM) methods are used as a tool to facilitate the decision making process. In this paper, we present a methodology called Multi-Criteria Geospatial Business Intelligence (MC-GeoBI) which aims to enhance Geo-BI applications by applying MCDM. The latter obviously offers several advantages in terms of decision making when one must take into account the multiple and contradictory aspects of the criteria. To illustrate this, an application model has been developed to select the most appropriate site for landfill of industrial wastes.
