Cartographic Animation

Cartographic animation's main goal is to depict change. The types of these changes are either categorized as temporal, or non-temporal. Most cartographic animations depict change over time (temporal). While non-temporal cartographic animations are rare, they are possible. Geographical areas are generally represented, while a factor (i.e., geospatial data, location, etc.) is contrasted with time.
The cartographic animation above shows the frequencies of traffic accidents in the United States, placed according to their actual locations.
