annual drift

In the reference for dynamic text in layouts, the North representation we have all syntax for displaying information except annual drift.

Do I miss something or is not accessible except in phyton scripting.

Since phyton scripting can’t be used in syntax inside dynamic text, I can’t find how to insert this information in my layout beside the magnetic declination.

Sadly, the Magnetic Calculator (which includes the drift component) is not supported in Pro, and the lack of "In Product Plan" status is discouraging:

However, I'm curious as to how you're making this a dynamic text element in Arc Map (if you are).

If you're ambitious you can try https://github.com/cayetanobv/declinationmap/blob/master/declinationmap/decmap.py

Magnetic North, who needs it? We all use GPS to calculate North now, right?

Hi, for the drift we can't use it, in mxd project directly, but that feature in available via python script. So we doesn't use it in regular projects but only in scripted one.

Cartographers use it to show north, magnetic north, declination and annual drift for printed product.

Someone Knows How to put annual drift declination in the layout map (ArcMap), to add below the topografic North Arrow?
