The bottleneck of the GIS-T data gathering is the heterogeneity between the information sources. The main purpose of this paper is to make clear the idea of semantic matching and to present a prototype implementation framework. After a short presentation of GIS-T characteristics and approaches of information interoperability, we focus an the establishment of the semantic matching, one of the most critical issue in the fusion. The matching problem is addressed in detail at three levels: the classes, the roles and the entities. Then we will go on to describe a proof-of-concept framework system that we are developing.
