Introduction

A geographic information system (GIS) is a tool for collecting, managing, storing, manipulating, and displaying spatial or geographic data. Geographic information science (GIScience), a vast subfield of the academic subject of geoinformatics, is commonly referred to by the abbreviation GIS. GIScience is the study of geographic information systems. A geographic data architecture, which has no such constrained parameters, is what goes beyond a GIS. Any information system that incorporates, saves, edits, analyses, distributes, and displays geographic information is often referred to by this name. Users may generate interactive queries (user-created searches), analyze geographical data, change data on maps, and show the outcomes of all these actions using GIS apps. The science that underpins geographic ideas, applications, and systems is known as geographic information science.

GIS is a general term that covers a wide range of technologies, procedures, and techniques. It is integrated into several processes and has numerous uses in the fields of engineering, management, planning, transportation and logistics, insurance, and business. Because of this, numerous location-enabled services that rely on analysis and visualization may be built on the foundation of GIS and location intelligence applications. By employing location as the primary index variable, GIS may link disparate pieces of data together. X, Y, and Z coordinates, which stand for longitude, latitude, and elevation, respectively, can be used to record locations or extents in Earth space-time. Any reference to a spatial-temporal location or extent that is based on the Earth should be able to be related to another reference and, eventually, to a “real” physical location or extent. This essential GIS feature is starting to open up new fields of study.
