Hi, I'm getting a wrong Lat Lon for this MGRS "04QEJ 97987 90670".

The correct lat/lon is "21.61643, -158.05325", but I'm getting

"20.79987937710965, -158.99999999999997"

Is there something that I am missing?

in core.py, line 21, you have the following:
rt = ctypes.PyDLL('libmgrs.cp35-win32.pyd')

this failed on my python 3.6 32 bit. I ended up changing it to this to get it to work:
rt = ctypes.PyDLL('libmgrs.cp36-win32.pyd')

The file itself is located in:
\Lib\site-packages\libmgrs.cp36-win32.pyd

I figure there should be some code that generates the libmgrs pyd file name based on the version of python installed and if it's 32 bit vs 64 bit. I don't know how to do this, but I figured I'd post this here incase someone knows how to and is willing to do so.

When the degrees of longitude reach 3 digits, the dmstodd() method gives incorrect results because the digits representing the minutes are extracted using a 2-character offset relative to the start of the string.

>>> import mgrs
>>> m = mgrs.MGRS()
>>> m.dmstodd("110000N")
11.0
>>> m.dmstodd("110000E")
11.0
>>> m.dmstodd("1110000E")
112.66666666666667
>>> m.dmstodd("1110000.00E")
112.66666666666667

This can be fixed by changing [2:-2] to [-4:-2] in two places in dmstodd() so that the two digits representing the minutes are extracted relative to the end of the string, not the beginning

I see other people are using windows and pyinstaller but I have not been able to resolve this issue. I installed mgrs into my venv and I'm trying to use pyinstaller to create an .exe. When I run the exe I get the following error:

mgrs.core.MGRSError: Unable to load libmgrs.cp37-win_amd64.pyd

I am using mgrs v1.4.2 and pyinstaller v4.2. I'm hoping someone has a solution for me. I tried the solution @uetacog proposed in issue #32 with no luck.

Can you push a new python 3.7 wheel for windows to pypi?

I get the subject error when trying to pip the package into my virtual environment. I'm on Windows 20H2. My python version is 3.9.5. pip is 21.1.1.

Hi Howard

Would be possible to have an explicit license for this library?

regards, Luigi Pirelli

If wheel is not installed the following in core.py silently fails, the DLL load fails.
Wheel solves the issue:

    libname = 'libmgrs'
    try:
        import wheel.pep425tags
        name = wheel.pep425tags.get_abbr_impl() + \
               wheel.pep425tags.get_impl_ver() + \
               '-' + wheel.pep425tags.get_platform()
        return libname + '.' + name + '.pyd'
    except ImportError:
        return libname + '.pyd'

Hello,

I have installed the library by pip (Windows 10, Python 3.8.2) and when I try to import mgrs, I see the following error:

>>> import mgrs
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    raise MGRSError("Unable to load %s" % lib_name)
mgrs.core.MGRSError: Unable to load libmgrs.pyd

Could you please advise which library/dependency I might be missing?

I wanted to leave a note in case anyone gets caught where I was, or I forget what I did.

When using pyinstaller to package something including mgrs, you need to explicitly include the .so file as pyinstaller will not include it.

pyinstaller <your options> --add-data=libmgrs.cpython-36m-x86_64-linux-gnu.so:. <name of script>

1. Notice it is .so : . You are telling it to put the so at the top level
2. The .so is in your site-packages location on ubuntu usually around ~/.local/lib/<python version>/site-packages/

Thank you for creating and maintaining this library. It's been very useful and easy to use.

The MGRSToUTM method is not working correctly for me. I've had success using the rest of the library, but converting from MGRS to UTM only seems to find the zone.

I am using mgrs 1.3.7 on an Anaconda distribution of Python 3.7. Thanks!

from mgrs import MGRS

convert = MGRS()
coords = "15SWC8081751205".encode('utf-8')

convert.toLatLon(coords)
>>> (38.40542615377341, -92.07439526029498)

convert.MGRSToUTM(coords)
>>>  (15,)

convert.UTMToMGRS(15,'N'.encode('utf-8'),580817,4251205)
>>> b'15SWC8081751205'

I haven't looked much into the bindings of the library, but I've noticed a significant overhead when processing a vector of multiple coordinates. Is it possible for the API to support lists and have the bindings consume them efficiently to increase performance?

I am attempting to use .toLatLon()
import mgrs m=mgrs.MGRS() m.toLatLon('some MGRS')

but get a tree error:
--RTreeError: Error in "Convert_MGRS_To_Geodetic": MGRS Errors: String Error --

Am i doing something incorrect? When i run it with the Lat/Lon variables, then .toMGRS(); it works fine. Without it, doing it all together as in the example, it provides tree errors.

Trying to get mgrs up and running on my mac. Get the following message.

According to https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system, S is used to designate the Northern Hemisphere. Why does Convert_Geodetic_To_UTM return N for positive latitudes. Shouldn't it be "S"?

Will there be wheels built for 3.11 & 3.12? Windows users on either of those versions will be running into issues with the tar.gz installation route.

I have used the mgrs library to get the tile for this point :

Lat = 39.9770
Lon = 116.3810

I get this tile:

50SMK4714425387

this does not correspond to any exsisting Sentinel2 tile. It should be 50TMK

I recently ran this on my Windows machine. When I ran it on a virtual environment in Anaconda, I had no problem, just had to revert the admin-root edit that was raised in a previous issue to get it working. However outside of the virtualenv, using Visual Studio I encounter this error every time I try to import mgrs:

FileNotFoundError: Could not find module 'libmgrs.cp38-win_amd64.pyd'. Try using the full path with constructor syntax.

Any idea what this could be linked to? I haven't had any success so far.

When trying to pip install mgrs in 64-bit Windows, I get "ImportError: cannot import name Library" on line 8 of setup.py. Based on the info at the link below, it looks like that import hasn't been valid in setuptools for a while and needs to be adjusted:

I am receiving an issue since wheel updated. I'm getting an error at

.env\lib\site-packages\mgrs\core.py in get_windows_platform_name
line 18 '-' + wheel.pep425tags.get_platform()

It looks like wheel now expects archive_root to be provided to wheel.pep425tags.get_platform().

It looks like the install requires of packaging was removed in version 1.4.3 (commit eee91f5), but the core module still imports packaging? This is causing an exception: ModuleNotFoundError: No module named 'packaging'.
