What is GIS?
Typically, the acronym GIS stands for Geographic Information System. However, it can depend on who you ask, as the “S” has been known to stand for Science as well. Simply put, a GIS is a collection of data with a spatial component that can be used for visualization and analysis. It is becoming increasingly useful in many occupations, including those in the fields of weather and climate.
