This course will be a hands-on introduction to QGIS, a widely used open source Geographic Information Systems program. GIS allows you to manipulate and visualize your research data which you can use to share with decision makers and inform future research. This is particularly useful to public health practitioners as geographic location is a determining factor in why something occurs where it does. This session does not assume previous experience with GIS software, though prior experience will most likely be helpful. We will talk briefly about background information, compare and contrast QGIS with ArcGIS, and walk through exercises using common tools and processes. The session will run between 75 and 90 minutes.
