Is there an easy way to get the angular difference between Grid North & True North in QGIS?

This is how I do it:

  1. Make a map in print composer
  2. Set the map CRS to whatever "WGS 84 / UTM zone" I need the grid convergence for.
  3. Place a North Arrow & synch it with map to True North.
  4. The Degrees of rotation on the image is my angular difference between TN and GN.

  • You can calculate it directly - for example, see gis.stackexchange.com/questions/115531/… Commented Jul 30, 2023 at 12:36
