The ARF hosts the Practical Workshops series which features trainings on ARF equipment as well as workshops demonstrating methods or techniques of general interest.
This page links to webpages dedicated to workshop topics (see below). There is also an ARF Practical Workshops youtube playlist with video tutorials linked to some of the workshops in the series.
In recent years we've focused on supporting QGIS and other free and open source software because they typically work on Mac and Linux as well as Windows, and everyone can make use of these workshops regardless of their access to licenses. In this way our efforts are going to supporting open software. There are many professionally developed tutorials for ESRI and other commercial products already available online.
