These projects were all examples of GISystems. Each offered different perspectives about their subjects and were able to do so with the utilization of GISystems. The “Mapping Twitter in Realtime” project presented an interactive search engine. Browsers can filter for tweets that contained specific “buzzwords” within a specific geographic location. This GIS uses VGI to supply the results for the search. We can draw numerous different conclusions from the various possible searches. This project is dynamic because the results for each search change as time passes because there is a constant supply of tweets. This project has potential for many applications, specifically commercial exploitation. Businesses can use this tool to observe the behavior of individuals in a certain geographic location and capitalize on their demands. This is an example of a highly interactive GISystem that provides a tool to the public. This project allows people to better understand the behavior of individuals in a geographic location.
