What does GIS stand for and what is its primary function?

GIS stands for Geographic Information Systems, and its primary function revolves around the collection, analysis, and visualization of spatial and geographic data. It allows users to create layered maps that combine various types of data, which can reveal relationships and patterns that are not easily visible otherwise. This technology is essential for a multitude of applications including urban planning, environmental monitoring, disaster management, and resource allocation. By effectively analyzing spatial data, GIS can help in decision-making processes by providing valuable insights and improving understanding of geographical phenomena.
