This is I know going to be of limited interest to many of you but I teach navigation and I am working on producing test questions and charts for assessing learners knowledge. My problem is solvable with post editing but as I am finding QGIS very versatile as I am learning it I think there may be another way to achieve this without needing post editing.
The effect I am looking for is this:
And in QGIS I have a layer with length of the vector lines and angle, and using the Vector Field marker symbol I get this:
This I am really impressed with and think I am probably asking to much to be able to either add colour bands as in image 1 or arrows between the lines labeled with the colour abbreviation.
One thought that I have is that perhaps there is some way to draw a radius and clip it to the sectors.
I am using Qgis Lyon and have a Mac so GIS alternatives are not easily possible.
