Five static graphic strategies support the transition from one spatial pattern to
another. Chess maps, as a telling sequence of instantaneous views, use a common
geographic framework to narrate a geographic story. By contrast, rate-of-change
maps use numerical measurements to describe spatial variation in the rapidity or
slowness of change. A third type, the dance map, mimics the step-by-step footwork
of rehearsed choreography, analogous to the movements of troops, materiel, and
intelligence in a military campaign (A highly focused dance map, the centrographic
map, treats a spatial-temporal narrative as a statistical summary.) Additional
strategies include flow maps and frontal maps, a military/meteorological analog.
Dynamic cartography and the interactive manipulation of history maps afford
new insights as well as alternative interpretations.
