Geographic information system (GIS)

Introduction

A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.

GIS technology can be integrated into any enterprise information system framework.

Benefits of GIS and how it can be used

GIS benefits organizations of all sizes and in almost every industry. There is a growing awareness of the economic and strategic value of GIS. But there is also a demand for geo-information as the result of an increase in environmental problems and the need to manage the natural and the social environment. 

The benefits of GIS generally fall into the following basic categories, according to ESRI:

  • Cost Savings and Increased Efficiency
  • Better Decision Making
  • Improved Communication
  • Better Recordkeeping
  • Managing Geographically

But one could easily argue that this list is not complete or to generic. Having said this, the benefits of using GIS in research are without doubt and GIS is more and more part of how we look at the world. This is valid not only for researcher of the militaru, but more and more also in day-to-day life. Consider the use of Google maps, location based services and sat navigation in cars.

GIS gives us a new way to look at the world around us. With GIS you can:

  • Map Where Things Are
  • Map Quantities
  • Map Densities
  • Find What's Inside
  • Find What's Nearby
  • Map Change
