The workshop scheduled for the 10th and 17th Sept deals with a number of navigation Apps on phones and some general background.
Before attending, attendees must download a few apps and set up the one called Viewranger.
Two PDF's are provided here to help "Downlaod Apps" (from google play store) and to "Setup Viewranger".
These are written for Android devices but should be relevant to Apple store as well.
The remaining PDF's are the notes intended to be used subsequent to the course for reference.
It may be posisble to follow the notes on a personal basis but that was not their primary function.
