A geographic information system—or GIS—can help you ride the rising swell of the “data tsunami” by encouraging new and interesting methods of data visualization. Maps can add huge value to health information, by helping to tell important stories and ask important questions.
If so, these mini tutorials are for you. For the beginning user who needs hands-on experience with the free and full-featured QGIS software, spend about 15 minutes with us in each of these six online modules.
You’ll get the technical knowledge you need to start working with your data. Each module includes videos, graphics, narration, and step-by-step screen shots from within QGIS, with several links to more resources.

Take a hand-held GPS receiver unit containing coordinate (x, y) data, plug it into your computer, and use it QGIS.
Format an Excel spreadsheet containing coordinate (x, y) data, import the data to QGIS and plot the locations.
Walk through through the process of collecting x, y coordinates (waypoints) with a hand-held GPS receiver unit.
Practice working with project files and properly referencing a shapefile. Practice fixing broken links and creating a shareable map package.
Practice choosing a projection that works with your data, and practice properly aligning data layers.
Learn the differences between raster and vector files, and practice working with and zipping “shapefiles”, the most common type of geographic data file.
