What does the acronym GIS stand for?

The acronym GIS stands for Geographical Information System. This term is widely used in the field of geography and data management to refer to a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographical data.

This definition reflects the core functions of GIS, which involves the integration of spatial data (where things are) and attribute data (what things are), allowing users to make informed decisions based on geographic contexts. The proper terminology emphasizes the system's focus on geographical data—meaning it deals specifically with locations and their relationships in the context of various information.

In contrast, the other options refer to terms that do not align with established definitions within the field. For instance, Geographical Integrated System and Geospatial Integration System suggest a different focus that does not capture the comprehensive nature of a GIS. Global Information System, while it sounds similar, lacks the explicit emphasis on geography that is central to GIS, making it less applicable to the standard understanding of the term.
