Introduction to Geographic Information System



Governments around the world are increasingly required to streamline business practices while adhering to complex political and regulatory requirements. To do so they must digest an immense amount of information to perform their duties in a fair and reliable manner. Almost all of this information is in someway tied to a geographic element.


GIS technology provides a flexible set of tools to perform a diverse array of functions handled by Government agencies and makes data sharing among departments easier so that the government can work as a single enterprise. As globalization of businesses and economies brings our world closer problems increasingly cross international boundaries with widespread implications. GIS helps national Governments collate and analyze the quantities of data needed to address these issues.

What can you do with GIS?



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


The geographic approach


Geography is the science of our world. Coupled with GIS, geography is helping us to better understand the earth and apply geographic knowledge to a host of human activities. The outcome is the emergence of The Geographic Approacha new way of thinking and problem solving that integrates geographic information into how we understand and manage our planet. This approach allows us to create geographic knowledge by measuring the earth, organizing this data, and analyzing and modeling various processes and their relationships. The Geographic approach also allows us to apply this knowledge to the way we design, plan, and change our world.
