I have a track between points A and B (black line) surrounded by a corridor 5 NM right & left of said track (reddish box).
What I need to extract is a vertical profile of the highest terrain in the corridor between A and B (crude representation in lower graphic) with an 100m increment.
I’m pretty sure this can be accomplished with
grdtrackbut my experimentation led nowhere so far.
Do you have a pointer for me where to start my research?
