Geographic Information Systems (GIS) are evolving computerized tools that greatly facilitate describing, modeling, and managing our natural resources. In this course, we will learn GIS tools, specifically ArcGIS and Google Earth, necessary to map and analyze the natural resources, focusing on the Hampshire College campus. We will learn about making and using maps, using technology ranging from counting footsteps to satellite navigation (Geographic Positioning Systems, GPS). We will learn how to create new GIS data as well as find appropriate existing data. We will learn how to use GIS tools to map features, analyze landscapes, model processes, and to manage natural resources. We will concentration on learning the practical aspects of GIS as a tool for natural science investigations. In addition to class activities, students will develop their own GIS projects during the second half of the semester that allow them to pursue their specific interests and refine their GIS skills.
