Abstract: The more information and data are produced in the actual information society, the more important become mechanisms and systems which organize data and provide information where to find which data. Most popular peculiarities of such information systems are digital archives, metadata information systems (MIS) or catalogue systems (CS). Recent initiatives offer access to a wealth of distributed data covered by the widespread information spectrum of different geodata disciplines, but offer only basic levels of interactivity and user assistance to access appropriate geodata and to interact with geospatial data archives. The most important issues to improve usability include semantic aspects (ontologies, formats and terminologies used in the different application areas), information retrieval aspects (interfaces between web portals and metadata servers respectively geospatial data archives as well as ranking aspects) and information visualization aspects (visual support in all phases of the information retrieval process).
