Final answer:
GIS provides advantages such as analysis of spatial information, creation of data overlays, and rapid map production.
Step-by-step explanation:
An advantage of a Geographic Information System (GIS) is that it can perform analysis of spatial information. GIS software allows users to analyze data and identify spatial patterns and relationships. Additionally, GIS enables the creation of data overlays that show the spatial relationships between two or more variables. Furthermore, GIS facilitates the rapid production of maps based on continuously updated information, allowing for timely and accurate visualization of geographic data.
