EMail: { Christophe.Marsala,Nara.Martini-Bigolin} @Hp6.fr Abstract In this paper, an approach is presented to search for useful patterns and dis- cover hidden information in Spatial Object-Oriented Databases (SOODB). Although many approaches of knowledge discovery for relational spatial da- tabases exist, there is a growing interest in mining SOODB. Indeed, object- oriented databases are well-suited to represent complex spatial information. Moreover, a very large number of existing spatial databases are ready to be mined. We propose an algorithm to mine a SOODB. After a spatial object query and a mathematical and fuzzy preprocessing, we apply decision tree based techniques and fuzzy set theory to discover knowledge.
