A geographic information system stores spatial information and represents it visually on a map. It is possible to apply several layers of different data types, so that you can analyze each one. The software supports decision-making on, for example, land-use planning, the setting-up of new sales outlets, or the management of geo-targeting.
GISs have existed since the early 1970s. Some have developed into advanced and complex software, with both deployment and use requiring extensive geographic representation skills. Since the 2000s, however, online services have been offering more easily accessible and intuitive applications adapted to the needs of more traditional fields of business such as entrepreneurship, marketing and sales.
