What is GIS?

Geographic Information System: An organized collection of computer hardware, software, geographic data, and personnel designed. In Geographic Information System is computer tool it collects data in to store, analyze, manipulate, and visualize geographical information related to the surface of the earth. The GIS has been called an ‘enabling technology,’ because it offers interrelation with the wide variety of disciplines which must deal with geospatial data.

A characteristic of a geographic feature typically stored in tabular format and linked to the feature in a relational database. The attribute of a well-represented point might include an identification number, address, and type.

GIS may be considered as a type of software in a computer system that allows us to handle information about the location of features or geographic information on the earth՚s surface. GIS is not just an advanced type of information system, but a combination of science and technology, which has several interrelated distinct disciplines.

Categories of GIS Terms

Basic GIS related terms can be divided into three main categories:

  • Data structure
  • Data management
  • Geo-processing and analysis
