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.

 

  • You already may be sold on that idea but wonder where to go with it.
  • You may have learned the basics of the GIS concept, but you’re now ready to use it.
  • You may already be attempting to work with your own geographic data, but have gotten stuck.

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.
