 Introduction to GIS-What is GIS?

Geographic Information System (GIS) is a computer-based tool that can map and analyze things and events that exist on the earth. GIS technology integrates the unique visual effects and geographic analysis functions of maps with general database operations (such as query and statistical analysis. This capability distinguishes GIS from other information systems, so that it has practical value in explaining events, forecast results, and planning strategies in a wide range of public and individual enterprises.

The main challenges facing the world today are: excessive population, environmental pollution, forest destruction, natural diseases, and so on. These are related to geographical factors.

These local problems also have geographical factors, whether it's a new profession, finding the most suitable soil for growing bananas, or calculating the best route for ambulances.

Map creation and geographic analysis are nothing new, but GIS performs these tasks better and faster than traditional manual methods. In addition, before the emergence of GIS technology, only a few people have the ability to use geographic information to help make decisions and solve problems.

Today, GIS is an industry with hundreds of thousands of people and billions of dollars in the world. GIS has been taught in schools, colleges, and universities around the world. Experts in each field are constantly aware of the superiority of thinking and working based on geographical points of view.
