Such early maps rarely had an associated scale, legends or oriented themselves to lines of longitude or latitude.
[3] Hal Moellering created another animated map in 1976 representing a spatiotemporal pattern in traffic accidents.
[2] In the 1990s, however, the invention of faster, more efficient computers, compact discs, and the Internet solved such problems.
Today, there are many free options for hosting animated maps online, including YouTube and GitHub.
However, in 1991, David DiBiase and colleagues developed visual variables unique to animated maps: duration, rate of change, and order.
[7] Duration is the unit of time a frame or scene is displayed, affecting the smoothness of the animation.
Maps on the weather channel use animation to emphasize the current and predicted paths of hurricanes.
The user can witness representations of changes over time, while manipulating the direction of view, the pace or the parameters of the map displayed.
There are many purposes which temporal animation might serve to depict: displaying and analyzing geographic patterns, meteorological events, climate, natural disasters, and other multivariate data.
Using legend in the temporal map will answer important questions related to the entity's existence (if?
