35,000 year ago, on the wall of  caves in France, Cro-Magnon hunters drew pictures of the animals they hunted. Associated with this drawing they also had lines and tallies thought to depict migration routes. These early records followed the two-element structure of modern Geographic information System . This well-known concept also known as GIS  – enables the possibility of knowing a graphic linked to an attribute database. The applications of GIS are unlimited, ranging from the simplest Real state to the most complex, specialized jobs such as national defense. GIS has developed and incessantly progressed over the centuries , until today.
