Installation

The easiest methods for installing pyproj are:

1. Use pip to install the binary wheels on PyPI:

pip install pyproj

• The MacOS and Linux wheels are powered by multibuild by Matthew Brett

• The Windows wheels are built by Christoph Gohlke

2. Use conda with the conda-forge channel:

conda install -c conda-forge pyproj

• pypoj is maintaned by the pyproj-feedtstock maintainers

• PROJ is maintaned by the proj.4-feedtstock maintainers

If these installation methods do not meet your needs, the section below provides further instructions for getting setup.

Datum Grids

You can add datum grids to your PROJ data directory for better accuracy for some transformations.

Available methods for download include:

1. Download stable from https://download.osgeo.org/proj or latest from https://github.com/OSGeo/proj-datumgrid

2. Use conda with the conda-forge channel:

conda install -c conda-forge proj-datumgrid-europe proj-datumgrid-north-america proj-datumgrid-oceania proj-datumgrid-world

Installing from source

Setup PROJ

PROJ 6.2.0+ is required when building from source. You can download PROJ from https://download.osgeo.org/proj or from https://github.com/OSGeo/PROJ. Installation instructions can be fount at https://proj.org/.

In the setup.py, the order for searching for PROJ is:

1. The PROJ_DIR environment variable

2. The internal PROJ directory (pyproj/proj_dir)

3. The proj executable in sys.prefix

4. The proj executable on the PATH.

For best results, set the PROJ_DIR environment variable to point to location of PROJ installation before running setup.py.

Examples of how to set the PROJ_DIR environment variable:

Windows:

set PROJ_DIR=C:\OSGeo4W\

Linux:

export PROJ_DIR=/usr/local

If you have a previous version of PROJ installed alongside the current version of PROJ, the best way to avoid conflicts is to:

1. Remove the previous PROJ from PATH & unset old PROJ_LIB environment variable (temporarily)

2. Install PROJ to the internal PROJ directory (pyproj/proj_dir)

3. Set the environment variable PROJ_DIR to point to the internal PROJ directory

4. Set the environment variable PROJ_WHEEL=true

5. Build pyproj

Setup pyproj

The data directory

The order of preference for the data directory is:

1. The one set by pyproj.datadir.set_data_dir (if exists & valid)

2. The internal proj directory (if exists & valid)

3. The directory in PROJ_LIB (if exists & valid)

4. The directory on sys.prefix (if exists & valid)

5. The directory on the PATH (if exists & valid)

Install pyproj

Note

Cython or pip>=10.0.1 is required for the installation.

Note

You may need to run pip with administrative privileges (e.g. sudo pip) or perform a user only installation (e.g. pip install –user).

From pypi:

pip install pyproj --no-binary pyproj

From GitHub with pip:

pip install git+https://github.com/pyproj4/pyproj.git

From cloned GitHub repo for development:

pip install -e .
