GIS has developed from Cro-Magnon hunters pictures on the walls of caves (http://erg.usgs.gov/isb/pubs/gis_poster/#history) to one of layering a multitude of information into computerized digital maps (http://envstudies. brown.edu/Thesis/2001/james/gishistory.html). In retrospect, with the advent of computer technology, GIS has developed from drawings on the wall of a cave to "a computer system capable of capturing, storing, analyzing, and displaying geographically referenced information; that is, data identified according to location" (http://www.nww.usace.army.mil/gis). The development of technology has given us the ability to respond to crisis situations in a more organized, safe and professional manner with common goals.
