This course combines lectures and hands-on weekly labs, to introduce students to Geographic Information Systems (GIS) tools and concepts. Using both commercial (ArcGIS) and open source software (QGIS, OpenLayers), we will cover: GIS data structures, map projections, collecting and creating GIS data, map making, exploring spatial patterns and data visualization. Topics will be framed using examples across disciplines (e.g. physical sciences, humanities and social sciences). At the end of the semester, students will complete a final project, in which they can apply their learning to their own major area of study. Despite the technical nature of this course, no prerequisites are required and material is appropriate for all students. Student learning will be assessed throughout the semester via class participation, a mid-term exam and the final project. This course will be taught asynchronously online.
