This is a fork of the mgrs library by Howard Butler, for my use case only. Please use and credit the original package.

GeoTrans provides C code for converting to and from MGRS, but well, it's C code :). This is a simple ctypes wrapper around two of the MGRS-related functions in GeoTrans.

This library has an internal copy of some of the files from GeoTrans 2.4.2.

• Allow user to override precision in UTMToMGRS

In a nutshell:

>>> import mgrs

>>> latitude = 42.0
>>> longitude = -93.0

>>> m = mgrs.MGRS()
>>> c = m.toMGRS(latitude, longitude)
>>> c
'15TWG0000049776'

>>> d = m.toLatLon(c)
>>> d
(41.999997975127997, -93.000000000000014)

>>> y = '321942.29N'
>>> yd = m.dmstodd(y)
32.328414

>>> d, m, s = m.ddtodms(32.328414)
>>> d, m, s
(32.0, 19.0, 42.290400)

You can also control the precision of the MGRS grid with the MGRSPrecision arguments in .toMGRS(). Other than that, there isn't too much to it.
