I am seeking a layer that shows magnetic declination. I have seen NOAA has a time slider in AGOL of historic declination but I am looking for a layer (feature class, feature layer, I would even take a shapefile if it was in that) representing those lines.
Here is an example map:- https://upload.wikimedia.org/wikipedia/commons/1/11/World_Magnetic_Declination_2015.pdf
Thanks for help, in advance!
