I am seeking to create an animated map illustrating the simultaneous movement of different objects across a large area over time. The display should be capable of playing automatically, or by manually selecting a date and/or period. I would like to retain the interrogable capability of a digital map (zoom and query a database or attributes) while paused, so I do not want to merely create raster images and and incorporate them into a slide show. Rather I want vector data moving across a base map. Does anyone know of suitable GIS software that can perform this trick?
