entity's location (when?), time intervals (how long?), temporal texture (how often), the speed at which change takes place (how fast?), and the order of change (what order?). Depending upon their construction, animated legends may distract the viewer from the animated map. Care must be taken to integrate the legend unobtrusively. Non-temporal map animation Non-temporal map animation shows changes against some other variables other than time. The variable might be a place, position, generalization level, etc. Non–temporal animation also serves when there is a need to show both the data set and the transformation that has been applied to it for its display. Non-temporal animation can be of many types according to the purpose they serve: Fly through animation This type of animation gives the viewer the feeling of flying through the landscape. Cartographic zoom animation This type of animation shows maps at different focus levels and viewers can change the scale of the map as desired. Classification animation Different methods of data classification are depicted in this animation. Generalization animation This type of animation uses a single classification method with multiple classes of data. Time is an important aspect in both animations. Real-time is depicted in temporal animation and presentation time (time to show the animation) is associated with non-temporal animation.
