Understanding Geographic Information Systems

May 20, 2013

Geographic Information Systems (GIS) are so common today, they are often a staple in peoples’ daily lives: Google maps, geotags, restaurant locators, etc.

GIS can be used to speed up any process that formerly relied upon paper maps. Also as technology advances, a variety of data, organizations and industries stand to benefit from utilizing GIS.

The analytical functions of GIS mean that geographic information can be used in unprecedented ways. According to Esri, international GIS software and geodatabase management supplier, the strategic value of using GIS falls into five categories:

-Cost savings and increased efficiency
-Better decision making
-Improved communication
-Better record keeping
-Geographic management

In this nine minute video, leaders from the Center for Applied Research and Environmental Systems (CARES) at the University of Missouri-Columbia sit down to discuss the basics of GIS, its applications and challenges.


It is important to appreciate that GIS does not always provide exact answers to problems, but by identifying trends based on geography, GIS can reveal patterns that can help make informed decisions.
