Abstract: The integration of data mining and geographic visualization techniques facilitates the identification and the interpretationof spatio-temporal patterns – a process recognized as knowledge construction. Knowledge construction is a dynamic process of manipulating 'data' to find, relate, and interpret interestingpatterns in large environmental data sets. Toward this end, anoverview of the main methods associated with the expanding fieldsof Knowledge Discovery in Databases (KDD) and Geographic Visualization (GeoVis) is provided. The paper explains how different methods can be combined in order to design a knowledgeconstruction process for the identification and interpretation of the space-time variability of both composition and structureof a pattern. Case studies, tools and prototype implementationsare described for illustrating how both KDD and GeoVis methods can be applied to uncovering spatio-temporal patterns. Finally,the specific underlying research issues are described, with particular emphasis on how these relate to the environmental sciences domain. Copyright Kluwer Academic Publishers 2002
