INTRODUCTION TO GIS

A geographic information system is a brilliant framework that can capture, analyze, and store geographic and spatial data.

In the least simple word, GIS is a computer system that presents all geographical data types of a location using different computer applications.

One needs to be quite open-minded to understand basic GIS and how to benefit from its application. GIS is a remarkably broad topic used to manage resources, crime mapping, establishing and monitoring natural disasters, etc. The list is quite long as GIS helps understand better about the specific location and its surroundings.

The most common GIS application is Google Map, right now on everyone’s Cell Phones for direction and traffic details of any route.

As this is a brief Introduction about GIS, it will give you an idea about its general use, component, and different applications.

History of GIS:

Roger F. Tomlinson is known as the father of GIS; he was the first person to use the GIS phase in his scientific paper. Later on, he designed a framework for a database that could store and analyze vast amounts of data for the Canadian government.

In the early 20th century, 2D maps were introduced, split into layers, vegetation for the first layer, and water for the second layer.

With the development in the computer field, GIS applications and frameworks also developed quickly.

Modern GIS technologies use digital information, for which various digitized data creation methods are used.

Now GIS can use any data that includes location. The location can be shown in many different ways, such as latitude and longitude, address, or ZIP code. There are Five essential elements/components of GIS.

GIS components:

GIS combines five essential components hardware, software, data, people, and methods. Hardware can be any computer desktop/high tech, or it can be a cellphone device depending on what GIS technology you need to use. Popular GIS softwares are AutoCAD Map 3D, Citymapper, Google Earth Pro, ArcGIS, QGIS, GRASS GIS, SuperGIS, SAGA GIS, and JUMP GIS.

GIS Data is the most crucial component; it is usually about the geographical detail of a specific area. GIS users vary from technical experts who design and manage the system to those who utilize it to help them achieve their everyday work. Furthermore, the last component is the Method; this component depends on each organization/business’s needs.

Use of GIS in different fields?

Many different fields required the use of GIS technology. As said earlier, GIS technology can be used for scientific research, resource management, and development planning.

Local and international companies use GIS to understand where they should build their new store or Frenchies. Marketing firms use GIS to select what product/item should be marketized to specific customers. The restaurant used GIS to find the best spot for their food and customers through it.

Scientists use GIS to analyze population statistics with resources such as drinking water and agriculture.

Animals’ and humans’ migration patterns are tracked through GIS for geological and biological examination.

GIS to help plan City, state, or federal officials their response in a natural disaster such as an earthquake or storm.

GIS maps can give calculated details to the government about what areas are most vulnerable or safe in an emergency. It also helps to locate emergency shelters and what routes people should take to reach safety.

GIS technology is also used by Engineers to maintain the design, implementation, and control of communication networks for the phones and the infrastructure needed for internet connectivity.

GIS technology is also used to develop road systems and transport infrastructure. There is no end to the kind of knowledge that can be analyzed using GIS technology.

Is the GIS developed for everyone?

The answer to this question depends totally on your requirements. If your organization/company relies on location data and manages its marketing on different data statistics, GIS is the best way. GIS marketing enables you to combine geographic, demographic purchasing, and spending characteristics into models that will carefully segment your customers.

Is GIS expensive?

No, not all GIS are expensive; some are free to use, and whereas some need an advanced computer system to run. But if you are running a small business, a simple personal computer would be enough to run GIS.

We will cover this software in our next articles.

How to get the best understanding of GIS?

There are many books available online on GIS that give a complete understanding of GIS. And many tools can help you execute GIS without knowledge of coding, we will disclose them in the next topics. So from my side, I would say it is pretty easy to know the basics of GIS and how it operates. Amazon has quite a handful of books on the GIS listed on our website.

As we mention earlier further topics will be covering details about GIS technology.
