simple parser for latitude-longitude strings
Project description
Code for parsing lat-long coordinates in “various” formats
Note: perhaps it would be better to integrate this with a more full featured lib like:
https://pypi-hypernode.com/pypi/LatLon23
But that one does not seem to support parsing unknown formats at this point – and it’s GPL, and perhaps a littel more complex and structured than it needs to be.
Formats supported:
Decimal degrees (easy):
23.43 -45.21
Decimal Degrees with quadrant:
23.43 N 45.21 W
Degrees, decimal minutes: (now it starts getting tricky!):
23° 25.800' -45° 12.600'
or:
23 25.800' -45 12.600'
or:
23° 25.8' N 45° 12.6' W
Degrees, Minutes, Seconds: (really fun!!!):
23° 25' 48.0" -45° 12' 36.0"
or:
23d 25' 48.0" -45d 12' 36.0"
or:
23° 25' 48.0" N 45° 12' 36.0" S
or – lots of other combinations!
Adding to the options:
This uses a pretty “stupid” algorithm – it assumes that all formats will be something like:
degrees [separator] minutes [separator] seconds [separtor] [N|S|E|W]
But that actually is pretty darn robust!
If you have other formats you want to be able to parse, please contribute tests! – And ideally a patch if the current code doens’t work.
