Geographic Information Systems (GIS) include a set of tools that allow people to map and annotate the locations of previous terrorist events or potential vulnerabilities to guard against. The maps can be distributed to intelligence agents and law enforcement personnel for viewing on hand held devices such as PDAs or smart phones. If an organization wants to learn about using GIS and does not want to invest in GIS software, they may purchase a book called “Getting to Know ArcGis” by Tim Ormsby et al. The book comes with step by step instruction on how to use GIS as well as a trial version of ArcGIS Desktop which is good for up to 180 days.
GIS maps can be simple or elaborate with as much data as is needed by their intended audience. I once spoke with a security professional at one of my monthly ASIS International meetings.
