Adaptive Map Visualization: from Context Selection to Web Service Configuration

The paper presents advantages of contextual cartography (or adaptive cartography) for the Digital Earth vision. Theoretical background connecting Digital Earth and contextual cartographic visualization is followed by practical example from an environment where the time is crucial: Crisis management. The example includes configuration process of Contextual Web Map Service (CWMS) called Sissi that was developed for providing map adaptation in web environment. The process described from cartographic point of view begins with selection and definition of contexts and context types, continues with appointing relevant spatial data and ends with implementation of cartographic methods in Sissi. The whole configuration process is documented with several map examples.
