ABSTRACT
GIS, remote sensing, mobile mapping, and geo-computation are major digital technologies supporting the processing and communication of geographical information. These cutting-edge technologies have developed to a point where a strong scientific and conceptual basis is required. Uncertainty is an inseparable component in science, and information and understanding about uncertainty are of crucial importance for the scientific development of geographical information technologies. The long-term effects of enhanced uncertainty handling in GISs and their peripheral technologies will be of both economic and cultural benefit, if they can be based on enlightened approaches to the collection, representation, analysis, and communication of scientific information about geographical uncertainty.
