摘要：In order to support authorities in performing their mandates to protect the population from floods and minimize damages,additional documentation methods are needed. Before and during a flood event, the use of appropriate real time hydrologicalmaps for improved early warning and monitoring activities is undisputed. After an event, however, the gained knowledge andexpertise (i.e. the “lessons learned”) must be retained and fostered. This should preferably take place in a formalized way andthe storage in a spatiotemporal database is one promising way to achieve this goal. However, such data-base driven mapinformation systems used as repositories for hydrological knowledge have so far gained little attention. The added values ofthese kinds of systems are: a more profound understanding of flood processes; a better basis for decision-making; and improvedmeans of post-event documentation and communication to peers and to the public.The usefulness of interactive map information systems for flood documentation and communication purposes is shown, using animplementation of the main following concepts: the integration of quantitative, qualitative, and multimedia data; combination ofthese data types for cartographic visualization; retrieval of historical maps in an easy, time-saving way; user-definedcustomization of map content to explore the interplay of flood-causing hydrological factors, during every flood phase; togglingof map symbols to represent data on different temporal aggregation levels; and the animation of both maps and connected mapelements (e.g. time series graphs).
