Google Maps are the front end of Geographic
Information Systems (GIS)
Google Earth is the front end of Remote Sensing

Geographic Information Systems (GIS) and Remote Sensing are highly related to Computer Information Systems (CIS)
But, GIS is not part of CIS, or not a CIS – Highly connected.
GIS processes locational data, or spatial data, or geographic data only.

Geographic Information Systems (GIS) - One word
different than the Computer Information Systems (CIS)
It is the “Geography” or “Digital Locational Information”

Definition of GISGIS: is a special information system that
combines digital map layers with
database to capture, analyze, and
model spatial (geographic) features or
objects
