These tutorial manuals were written to accompany day-long, introductory GIS workshops that I teach with QGIS. These are the most recent versions, free for classroom use and self-directed learning under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. Download the data file, unzip it, and then follow the exercises in the manual. These tutorials were written for the long term releases of QGIS – not the latest releases. It’s best to stick with the version the manual was written for if you are new to GIS and are going to use this manual as your introduction.
