ABSTRACT
The integration of geographical databases (GDB) describing the same real world from different sources is becoming a growing issue. At present, many geographical databases exist to jointly describe the same reality at different spatial and semantic resolutions. Many applications, such as quality evaluations, incoherence detection, propagation of updates, and the study of several adjacent zones, require the integration of geographical databases. The integration process (Devogele et al., 1998; Sheeren et al., 2004) is usually carried out in three stages. The first stage is pre-integration, consisting of enrichment of the schema sources and standardization of the models. The second stage consists of schema matching (Gesbert, 2005)
