Geographic Information Systems (GIS) at Roane State Community College

What is GIS?

G - Geographic I - Information S - Systems

Why Use GIS?

Because much of our work is inherently spatial in nature

Because we deal with a wide variety of complex issues in many disciplines conducive to modeling

Because we frequently create information well-suited to storage in databases

Because we make frequent use of maps and mapping

Program FocusLearning GIS

Geographic Information Systems (GIS) at Roane State Community College

The intent and focus of the program is to give the students a firm foundation in the concepts and principles of GIS, such as understanding map projections, scale, topology, database concepts and spatial analysis techniques.

Students learn to design, develop, complete and present GIS projects at a professional level. Students are also educated in problem solving techniques.
