GIS stands for “Geographic Information System”. A regional information system, to handle, a digital data management system used to recapture, evaluate, and present spatial data. Information utilized and taken in a GIS generally are displayed on other hard-copy or paper maps.

GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively.

All Earth-based spatial–temporal location and extent references should be relatable to one another and ultimately to a “real” physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry.
