pytzwhere is a Python library to lookup the timezone for a given lat/lng entirely offline.
Version 3.0 fixes how pytzwhere deals with holes in timezones. It is recommended that you use version 3.0.
It is a port from https://github.com/mattbornski/tzwhere with a few improvements. The underlying timezone data is based on work done by Eric Muller
If used as a library, basic usage is as follows:
>>> from tzwhere import tzwhere
>>> tz = tzwhere.tzwhere()
>>> print tz.tzNameAt(35.29, -89.66)
America/Chicago
The polygons used for building the timezones are based on VMAP0. Sometimes points are outside a VMAP0 polygon, but are clearly within a certain timezone (see also this discussion). As a solution you can search for the closest timezone within a user defined radius.
Dependencies:
numpy (optional)
shapely
