What is GIS? https://gisgeography.com/whatisgis/

GIS stands for Geographic Information Systems. It's a computerbased tool that examines spatial relationships, patterns, and trends in geography. Using a GIS allows you to store, analyze, and visualize data for geographic positions on Earth’s surface.

There are 4 main functions of a GIS:

1) First, a GIS has a data management component for storing geographic locations.
2) Secondly, a GIS visualizes geographic data typically using maps.
3) Thirdly, GIS software can analyze spatial relationships and patterns using geoprocessing.
4) And finally, a GIS can either create new data or edit existing data.
