Geographic Information Systems (GIS) is a sub field of geography that enables users to manage, visualize, and analyze spatial data. It has become an essential tool in the Geographer's tool kit for understating spatial relationships about places and features on the Earth’s surface.
GIS is composed of two distinct parts: geospatial data and computer software. Geospatial data is collected or downloaded, then it is imported into GIS computer software that allows users to visualize and analyze that data.
