Location map notes

Standard usage for location maps is to set the boundaries in such a way that any location can be replicated on the location map using pixel co-ordinates.

For example, a 2048x2048 image should have boundaries of 0, 204.8, 0, 204.8.

This allows a point at pixel co-ordinates (1567,1056) to be plotted precisely in degrees and minutes by using the integer component as the number of degrees, and then multiplying the decimal component by 60 to get the number of minutes.

Like so:

d = int(156.9°) = 156°
m = int((156.9° - 156°) × 60) = 54'
156.9° = 156° 54'
