All the GIS (Geographic Information System) Questions & Answers given below include a hint and wherever possible link to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on the GIS (Geographic Information System) topics.

GIS stands for Geographic Information System, is a computerized tool that captures, manipulates, stores, presents, and manages the data related to geography. It was coined by Roger Tomlinson in the year 1968 and was given the title "The Father of GIS". GIS helps in decision-making, solves problems related to other geographic issues, and visualizes spatial environmental data. It represents the data related to space in form of maps like Google maps, Apple maps, and open street maps. This map includes spatial data in terms of where the physical things are exactly located, their quantities, densities, routes, nearby location, etc. GIS software applications can be downloaded on the user's smartphone or can be viewed on a computer system, which allows the user to perform analysis, spatial information, create searches, store data, edit data, and share the data visually. Few of the GIS applications are GMaps and OMaps.
