John's ArcGIS Tutorials
From Help Wiki
These tutorials were developed initially as scripts for my own introduction to ArcGIS course, Mapping for Change. They are not perfect, and may contain some errors. I encourage people who find errors (and verify the proper correction) to edit these tutorials in order to make sure they are as current and correct as possible. Eventually, I hope to enhance the tutorials with screenshots and more detailed steps. In the meantime, I hope you find them helpful!
