Mapping and GIS
ES/GE 217. Mapping and GIS. Geographical information systems (GIS) are computer-based systems for geographical data presentation and analysis. They allow rapid development of high-quality maps, and enable sophisticated examination of spatial patterns and interrelationships. In this course students learn the principles of GIS through extensive computer use of ArcGIS (ESRI). Geological and environmental projects introduce students to cartography, common sources of geographic data, methods for collecting novel spatial data, and data quality. Finally, students learn to extend the capabilities of GIS software to tackle more advanced spatial analysis tasks by completing an independent project. Lectures supplement the laboratory component of the course. Prerequisite: one 200-level course in environmental studies or one 100-level course in geology. Not open to students who have received credit for Environmental Studies 217. Enrollment limited to 20. [S] [L] [Q] Offered with varying frequency.
