GPS.         


        

Answer 1

i have seen nobody mentioned this: https://pypi.python.org/pypi/LatLon/1.0.2

from fractions import Fraction
from LatLon import LatLon, Longitude, Latitude

latSigned = GPS.GPSLatitudeRef == "N" ? 1 : -1
longSigned = GPS.GPSLongitudeRef == "E" ? 1 : -1

latitudeObj = Latitude(
              degree = float(Fraction(GPS.GPSLatitude[0]))*latSigned , 
              minute = float(Fraction(GPS.GPSLatitude[0]))*latSigned , 
              second = float(Fraction(GPS.GPSLatitude[0])*latSigned)
longitudeObj = Latitude(
              degree = float(Fraction(GPS.GPSLongitude[0]))*longSigned , 
              minute = float(Fraction(GPS.GPSLongitude[0]))*longSigned , 
              second = float(Fraction(GPS.GPSLongitude[0])*longSigned )
Coordonates = LatLon(latitudeObj, longitudeObj )

now using the Coordonates objecct you can do what you want: Example:

(like 46°56′48″N 7°26′39″E from wikipedia)

print Coordonates.to_string('d%°%m%′%S%″%H')

You than have to convert from ascii, and you are done:

('5\xc2\xb052\xe2\x80\xb259.88\xe2\x80\xb3N', '162\xc2\xb04\xe2\x80\xb259.88\xe2\x80\xb3W')

and than printing example:

print "Latitude:" + Latitude.to_string('d%°%m%′%S%″%H')[0].decode('utf8')

>> Latitude: 5°52′59.88″N
