GEOS Dependency

GEOS (Geometry Engine - Open Source) is a C++ library that supports spatial operations in various GIS software and libraries, such as Shapely—a Python package used for geometric object manipulation. GEOS implements the OpenGIS Simple Features for SQL, essential for operations like area calculation, intersections, and other spatial analyses in Shapely. For Shapely to function correctly, GEOS must be installed and configured in your environment.

How to Install GEOS

The installation of GEOS varies depending on your operating system:

For macOS

You can install GEOS using Homebrew:

brew install geos

For Ubuntu/Debian

You can install GEOS from the package manager:

sudo apt-get install libgeos-dev

For Windows

Installing GEOS on Windows can be more complex because it involves setting up the library manually unless you use a package manager like Conda, which simplifies it:

conda install -c conda-forge geos
