Geographic Information System (GIS)

What is Geographic Information System (GIS)?
A geographic information system (GIS) is a system for collecting, analyzing, storing, manipulating, presenting and managing all types of geographic data, such as: B. Information from maps, GPS and ubiquitous data such as locations of landmarks and areas of accidents. It can display data related to locations on the earth's surface and show these different types of data on a map so that people can see different data patterns and relationships.

A GIS integrates hardware and software to collect / analyze data so that users can question, understand, and visualize data in a variety of ways to uncover patterns or trends in the form of maps, globes, charts, and reports. This helps users answer questions and solve problems, which is useful because by viewing and analyzing visual data, the human mind can more easily discern patterns and relationships.

The primary advantage of a GIS is its cross-disciplinary communication. Because people can understand visual impulses, it enables better communication. A GIS also makes better decision-making easier. For example, it is easier for a civil protection coordinator to manage and move resources when a field can be visualized to determine which areas need help and the urgency and capacity of that help.

Google Maps is the best example of a GIS.
