azimuth2compass(double azimuth [, int resolution [, int verbosity]])
The azimuth2compass function converts a numerical azimuth value
(degrees of rotation from 0 degrees north) and converts it into a
compass heading, such as N or Southeast. The exact text
returned is controlled by two optional parameters, resolution
and verbosity.
Resolution determines how fine-grained the values returned
are. There are 4 possible values:
-
1 - Only the four cardinal directions are used (N, E, S,
W) -
2 (default) - Inter-cardinal directions (N, NE, E,
etc.)-
3 - In-between inter-cardinal directions (N, NNE, NE, ENE,
E, etc.) -
4 - ``by'' values (N, NbE, NNE, NEbN, NE, NEbE, ENE, EbN,
E, etc.)
Verbosity affects how verbose the resulting text is. There are
two possible values:
-
1 (default) - Use initials for direction values (N,
NbE, NNE, etc.)-
2 - Use full text for direction values (North, North by
east, North-northeast, etc.)
For an azimuth value of 105, here are some example results of
azimuth2compass:
azimuth2compass(105): E
azimuth2compass(105, 3): ESE
azimuth2compass(105, 4): EbS
azimuth2compass(105, 1, 2): East
azimuth2compass(105, 3, 2): East-southeast
azimuth2compass(105, 4, 2): East by south
