Improved visualization techniques for spatiotemporal data have potential to reveal interesting insights from GIS data. Thus, visual analytics has captured the attention of GIS researchers in the recent past. Furthermore, developments in free tools, such as Google Map API and OpenStreetMap, provide easy access to geospatial data that can be leveraged by visual analytics. In this chapter, we propose such a system that utilizes free GIS APIs to visualize spatiotemporal data effectively. Our application allows a user to create a time slide bar control to connect time and position of various GIS objects on a map and to display them in animated mode. This control can handle vector and raster data with equal ease. The resulting effective visualization makes it is very easy to understand some complex spatiotemporal patterns, as exemplified in this chapter.
