Question

python是否包含任何用于将DMS格式的经度和经度转换为十进制格式的库,反之亦然？

Answer 1

# -*- coding: latin-1 -*-

#example for : 0°25'30"S, 91°7'W

def conversion(old):
    direction = {'N':-1, 'S':1, 'E': -1, 'W':1}
    new = old.replace(u'°',' ').replace('\'',' ').replace('"',' ')
    new = new.split()
    new_dir = new.pop()
    new.extend([0,0,0])
    return (int(new[0])+int(new[1])/60.0+int(new[2])/3600.0) * direction[new_dir]

lat, lon = u'''0°25'30"S, 91°7'W'''.split(', ')
print conversion(lat), conversion(lon)
#Output:
0.425 91.1166666667

而对于另一种方式:

def deg_to_dms(deg):
    d = int(deg)
    md = abs(deg - d) * 60
    m = int(md)
    sd = (md - m) * 60
    return [d, m, sd]

#output
>>> deg_to_dms(91.1166666667)
[91, 7, 1.199953203467885e-07]
>>> deg_to_dms(0.425)
[0, 25, 30.0]
