There will be developed a virtual learning environment (VLE) in order to gain a thorough understanding of the geological structure of Belgium. This EULA will consist of an interactive 4D GIS environment. This EULA is the process meant that pupils an extensive amount of information on the geology of different locations of Belgium in an interactive way in order to obtain a thorough understanding. By processing this information, students are helped by the electronic learning environment. The emphasis is on the high participation of the students. A virtual expedition thus leads youths throughout geological structure of Belgium. Along this virtual "4D environment" they acquire knowledge and prove their skills by solving questions and performing tasks. In this way they can get equipment needed to provide a synthesis of the geological origins of Belgium.
