Current technological developments allow the collection of huge amounts of spatio-temporal data that are usually stored and afterwards analyzed to support the decision-making process. Analytical tools, ranging from statistical packages to sophisticated data mining algorithms, allow the analysis of such data sets. This workshop will address the analytical methodologies, strategies or techniques that allow the analysis of complex data, namely spatio-temporal data, and the suitable visualization mechanisms that ensure an effective integration of this type of data in the decision-making process in organizations.
