Abstract: The more information and data are produced in the actual information society, the more important become mechanisms and systems which organize data and include information where to find which data. Most popular peculiarities of such information systems are digital archives, metadata information systems (MIS) and catalogue systems (CS). These systems are used as preparatory step/tool for any other domain-specific applica-tions such as site planning projects. Recent initiatives both on national and international basis- in the area of spatial libraries and environmental MIS/CS provide access to a wealth of distributed data, e.g. necessary data in the context of site planning. On the other hand they offer only basic levels of in-teractivity and assistance to the user. This includes all steps of the information retrieval process: Query formulation, query modification, comparison of (metadata) result sets and search result presentation. Referring to this lack of usability, there are special action lines
