Geographic Information Systems (GIS)

A geographic information system (GIS) is a framework for gathering, managing, and analyzing data. Rooted in the science of geography, GIS integrates many types of data. It analyzes spatial location and organizes layers of information into visualizations using maps and 3D scenes. (footnote citation for this text - https://www.esri.com/en-us/what-is-gis/overview)
