Deriving bearing in degrees minutes seconds format from field calculator
I'd like to know if there's a formula for calculating bearings of lines in degrees minutes seconds format. I already have been able to get the bearings in decimal degrees using:
CONCAT(format_number(degrees(azimuth(start_point($geometry), end_point($geometry))), 2), '°')

If you want to use an intermediate field containing the bearings in decimal degrees, I suggest not adding the '°' sign, but create a field "DEGREES" of type 'real' and populate it like this:
degrees(azimuth(start_point($geometry), end_point($geometry)))
Then, by using this field calculator expression in a new text field, you can format your angle in degrees, minutes, seconds:
concat(floor("DEGREES"), '° ', floor("DEGREES"*60 % 60), ''' ', "DEGREES"*3600 % 60, '''')
Or you could also do it with a single expression from the geometry directly:
concat(floor(degrees(azimuth(start_point($geometry), end_point($geometry)))), '° ',
floor(degrees(azimuth(start_point($geometry), end_point($geometry)))*60 % 60), ''' ',
degrees(azimuth(start_point($geometry), end_point($geometry)))*3600 % 60, '''')
