Garden Gnome Software

I'm new and I really don't understand what setting north is all about . What it does and is it really about true north or is it about setting it so it will place the directional arrows in the correct location. I have a 5 node tour that I would like to place on Google my business as a see inside . My outdoor strat image is gps tagged and the 4 interior images are not . I'm just trying to figure out what north is all about . Any help would be appreciated.

If you have not already done so you might want to review this Documentation "Setting North and Setting the Radar Beam":
