Shapely and PyGEOS

Shapely is a Python package for manipulation and analysis of planar geometric objects.

PyGEOS is a C/Python library with vectorized geometry functions

Shapely and PyGEOS doesn’t have python binary wheels for windows on arm. You can find instructions on building both packages locally here.

Compile LibGEOS

Shapely and PyGEOS require GEOS library.

No prebuilt libraries are provided for windows on arm yet. So you will need to build it locally.

We’ve tested https://github.com/libgeos/geos/releases/tag/3.10.2 but other versions probably would work as well.

And run the following cmake commands to build and install the library


cmake -B build -A ARM64

cmake --build build/ --config Release

cmake --install build/ --config Release

This will install library to `C:\Program Files(x86)`, you can change it you providing required prefix to cmake command.

Shapely and PyGEOS look for couple of environment variables to find out GEOS path. Please set the following environment variables.

$env:GEOS_LIBRARY_PATH="C:/Program Files/GEOS/lib"
$env:GEOS_INCLUDE_PATH="C:/Program Files/GEOS/include"

Shapely and PyGEOS can be installed with pip

pip install shapely

pip install pygeos
