GIS is the nervous system for the planet.

GIS is kind of like Google Earth, but better

So, what really GIS is?
Geographic information system (or geoinformation system, or simply GIS) is modern information
technology had targeted for fixing, holding, editing, analysing and displaying all kinds of georeferenced information.
Using of GIS allows you to deeply analyze datasets by its spatial georeference. GIS allows to
combine a model of terrain (maps, layouts, imagery, etc) with any table-formed information.
for the first time GIS principles have applied in 1832 for epidemiologic analysis of cholera infection spreading. The real reason have obtained
by adding the infection cases locations on a map and relating these addreses with locations of nearest water sources. In the clusters of infection
cases with high death rate had found water supply points owned by one company which provided contaminated water supply.
However, in modern meaning, for the first time about GIS had declared only in 1968 after publication 'Geographic Information System for Regional Planning'
by Roger Tomlinson. After his approach has developed — he had rightly named 'father of GIS'.
Today, in the era of powerful computational technologies and satellite navigation systems, geographic information systems become
the authoritative science and commercial direction with unlimited analytical perspectives.
What industries are currently using GIS?
As you can see on the illustration below, GIS could be used practically for every professional and scientific cases. The most broad implementation of GIS now have such industries:
- bioresource management and agriculture;
- political and marketing investigations;
- urban infrastructure planning and management;
- engineer communications planing and management;
- emergency management;
- mining ang other Earth exploration;
- environmental studies
In general there are no real limits for using of GIS, and these technologies can be implemented for researching and optimization into any industry.
What pros achieved from using of GIS?
Main reasons why hundreds of thousands leading companies and experts from plenty of industries are using GIS are:
It is not the whole list of possible applications of geographic information systems.
In the best way it was illustrated by ESRI founder: (read about comparision between ESRI products and our solutions based on QGIS
) — "The application of GIS is limited only by the imagination of those who use it".
