Choosing Tools: Nine Metaphors of Four-Dimensional Cartography

Animated maps are now technically and economically feasible. Like other forms of cartography, map animation has some unique design considerations, which involve a variety of tradeoffs. Making these tradeoff decisions is easier if we acknowledge that different animation software packages seem to embody a number of different perspectives - a 'flipbook' style of animation, for example, is suited to different tasks than a 'stage-and-actor' or a 'model-and-camera' program. This paper contrasts nine different animation metaphors, with special attention to the degree to which a given tool allows a cartographer to make particular kinds of revisions
