While cartographic animation has become a practical alternative, it is mostly used to depict both spatio-temporal and non-temporal changes. The paper concentrates on the use of dynamic symbols on a static base map. A visual test was carried out to obtain some perspectives about the cartographic communication of blinking point and line symbols. The results confirmed that dynamic symbols tended to attract the attention of the users in general and even in situations when the foreground–background contrasts were poor. Their effectiveness was more pronounced with symbols of a larger size but tended to diminish with an increasing number of blinking symbols. It was also observed that users were able to perceive differences in the frequency of flickering, particularly when the variation was large. The line animation method (marquee and grow-out) did not yield a substantial difference in visual responses in the case of blinking line symbols.

Thematic knowledge for the generalization of land use data / Wenxiu Gao in Cartographic journal (the), vol 41 n° 3 (December 2004)

In this study, such knowledge is classified into two broad types, i.e. general knowledge and thematic knowledge. General knowledge covers the basic and common restrictions and specifications for generalization of geographic data. Thematic knowledge describes the special restrictions and specifications for a specific geographic data application. The paper emphasizes the use of thematic knowledge in detail for land use data generalization. Three main types of thematic knowledge are identified, i.e. nature-based, culture-based and application-specific. Such thematic knowledge is then represented using the so-called production-rule method to become generalization rules. These rules are built in a prototype system to guide the implementation of land use data generalization. Real-life data have been used for testing and very promising results have been obtained from this system.
