Hello João,
Thank you for your reply. I did look at that list but was unable to find the legend explaining the different types of track until the previous response. I’m sill not sure how I would find that explanation without using the link.
A symbol that I have been unable to work out is a red circular dot with two white lines in it at right angles to one another, like the capital letter L. I have seen these on the map spaced out in a chain, connected by black lines. Do you know what these are, by any chance?
With thanks in anticipation,
Simon
