Shapely can also integrate with other Python GIS packages using GeoJSON-likeĭicts. Modules provide dumpers and loaders inspired by Python’s pickle module. Using several well known formats and protocols. Shapely does not read or write data files, but it can serialize and deserialize If geos-config is not on yourĮxecutable, it can be specified with a GEOS_CONFIG environment variable, e.g.: $ GEOS_CONFIG =/path/to/geos-config pip install shapely Integration If you’ve installed GEOS to a standard location, the geos-config program willīe used to get compiler and linker options. Install the GEOS library, Cython, and Numpy on your system (using apt, yum,īrew, or other means) and then direct pip to ignore the binary wheels. Version of GEOS than the one included in the project wheels you should first That depend on GEOS (such as cartopy or osgeo.ogr) or want to use a different If you want to build Shapely from source for compatibility with other modules Windows users have another good installation options: the wheels published at If you use the Conda package manager to install Shapely, be sure to Homebrew, and is also provided by popular Python distributions like Canopy andĪnaconda. Shapely is available via system package management tools like apt, yum, and Python Package Index with a recent version of pip (8+): $ pip install shapely Linux, OS X, and Windows users can get Shapely wheels with GEOS included from the Know how to use their platform’s compiler and Python SDK, and a good option for Built distributionsīuilt distributions are the only option for users who do not have or do not Shapely may be installed from a source distribution or one of several kinds See the manual for more examples and guidance. > from shapely.geometry import Point > patch = Point ( 0.0, 0.0 ).
