Thank you. Will use this in my project.
In case someone want's to apply for a Numpy Array of angles I've adapted as such...
def degrees_to_cardinal(d):
'''

'''
dirs = np.array(["N", "NNE", "NE", "ENE", "E", "ESE", "SE", "SSE",
"S", "SSW", "SW", "WSW", "W", "WNW", "NW", "NNW"], dtype='U')
ix = np.round(d / (360. / len(dirs))).astype('i')
return dirs[ix % 16]
I did the following:
DIRECTIONS = [
'N', 'NNE', 'NE', 'ENE', 'E', 'ESE', 'SE', 'SSE', 'S', 'SSW', 'SW', 'WSW',
'W', 'WNW', 'NW', 'NNW', 'N'
]
x = 155 # anything 0 - 360
cardinal = DIRECTIONS[round(x / 22.5)]
Note the extra N
at the end of the list.
This should probably be made a package
