摘要：Because automatic methods for thematic interpretation purposes are not (yet) able to handle complex data sources and criteria, we propose to go back to, respectively to integrate, the classical visual approach and to improve it with methods and tools of geovisualization. For the case of a change detection and analysis we developed a concept for an assistant that applies the principle of the basic questions related to spatio-temporal phenomena ("where", "when" and "what") from which two parts form the input and the remaining one the output of such an operation. A simple example shows the additional value of this approach, in particular the chance to differentiate between existential changes and property changes of objects.
