What is GIS: Geographic Information System
A geography information system (GIS) is a software tool which is used for analysing and surveying geographic information and occurrence(events) that occurs on Earth. These tools allow users to capture, store, edit, manage and display spatial data that means the data related to positions on Earths surface. GIS has a feature that can display different data on one(single) map, such as buildings, roads, vegetation & rivers. This enables the people to easily see, examine, and understand patterns and relations among spatial data. The map which we see on our phone or internet is using GIS technology.
GIS tells that every object on earth has its location which can be represented by a, b and c value means latitude, longitude and altitude respectively. Along with this GIS also stores some other information about the object for example for a particular state/city it can include data about people, such as income, population or education level. It can include information about the sites of factories, hospitals, schools, roads and electric power lines.
GIS provides many applications which can be used for planning, management, transport, insurance, telecommunications, and business. GIS is useful for almost all organizations of any size and almost every industry.
