GIS stands for “Geographical Information System.” It refers to a software system that allows to acquire, analyze, visualize, and share information derived from geographic data and represent what occurs in it. The technology behind GIS integrates the features of a database that allows performing searches, storing data, and drawing graphs with a map that provides spatial data and geographical representations. Thus, GIS software can handle a large amount of geo-referenced information. These data can be expressed through maps or tables and referred to extensive portions of territory as needed. GIS has many differences from other IT systems, as it offers infinite possibilities of use for all needs related to geographical components. From geo-location of objects to the study of landscape evolution, GIS allows detailed and complex planning of the territory and the actions to be performed on it.
