Fill missing values in a grid by solving Poisson's equation via an iterative relaxation scheme.

The easiest way to install is with conda:

conda install -c conda-forge gridfill

You can always build from source yourself once you have the necessary dependencies installed (see the requirements section below). Checkout the gridfill repository from Github and:

cd gridfill/
python setup.py install

For installation gridfill requires:

• numpy
• Cython
• setuptools

gridfill can also operate on iris cubes, which requires the iris package to be installed.

For development the pytest package is required in order to run tests. In order to run all tests you should also install iris.

Tests can be run in-place but you must first compile the extension module:

python setup.py build_ext --inplace
python -m pytest

Tests can also be run against the installed version:

python -m pytest --pyargs gridfill.tests
