Understanding Geographic Information Systems

Since the beginning of the environmental movement during the 1970s, scientists have grappled with the complexity of environmental problems. Initial attempts to integrate the diverse nature of environmental information through manual overlays was only partially successful. The advent of more powerful computers gave scientists the opportunity to model these complex interactions through geographic information systems (GIS).

However, a GIS is less about using computer hardware and software than learning how to think spatially. The most important part of the system is the analyst’s ability to recognize and understand spatial patterns. For example, a typical problem is analyzing the relationship between hydrological systems and riparian habitats.

What happens to riparian habitats when the hydrological regime is affected by a dam? What is the size of a buffer system that would limit the amount of pollutants migrating to the stream? How do you model these interactions to suggest alternatives that would maintain the integrity of the system? These are typical “what if” questions that can be asked using GIS.

Geographic Information Systems Course Descriptions

EES 340 – Geographic Information Systems with Lab – 4 Credits
This is an introductory course to GIS. GIS is a spatial analysis system designed to improve environmental decision-making. Course objectives are to examine how digital earth resources data are collected, stored, analyzed, and displayed. The emphasis will be on natural resource problems, although we will discuss additional applications.

EES 342 – Advanced Geographic Information Systems with Lab – 4 Credits
This course explores advanced topics in the spatial analysis of natural resources. We will investigate strategies for the integration of digital earth resources data in environmental modeling and gain experience in the use of advanced spatial data analysis software.

EES 444 – GIS Applications in Environmental Science – 3 Credits
This course will be a capstone experience in integrating environmental and computer science courses and applying that knowledge to an environmental problem. Each student will develop a GIS application project and present it in a written, poster, or oral format.
