Nansat is a scientist friendly Python toolbox for processing 2D satellite earth observation data.

The main goal of Nansat is to facilitate:

• easy development and testing of scientific algorithms,
• easy analysis of geospatial data, and
• efficient operational processing.

You can find a detailed description of Nansat in our paper <https://openresearchsoftware.metajnl.com/articles/10.5334/jors.120/>_ published in Journal of Open Research Software <https://openresearchsoftware.metajnl.com/>_ in 2016.

... and you can join the mailing list <https://groups.google.com/forum/#!forum/nansat-dev>_.

We appreciate acknowledgments of Nansat. Please add a reference to the following paper if you use Nansat in scientific publications:

Installation

An easy way to install Nansat requirements on any platform is to use Anaconda_ (download installer <https://conda.io/miniconda.html>_).

.. _Anaconda: http://docs.continuum.io/anaconda/index

::

# create environment with key requirements
conda create -y -n py3nansat gdal numpy pillow netcdf4 scipy
# activate environment
conda activate py3nansat
# install nansat
pip install nansat
# launch python
python

Another option is to use Docker containers (read about Docker <https://docs.docker.com/>_).:

::

# download image with everything pre-installed and launch ipython
docker run --rm -it -v /path/to/data:/data akorosov/nansat ipython

Example

::

# download a test file
wget https://github.com/nansencenter/nansat/raw/develop/nansat/tests/data/stere.tif

.. code:: python

# import main file opener
from nansat import Nansat

# open a test file
n = Nansat('stere.tif')

# see file content
print(n)

# create RGB with auto-stretched histogram
n.write_figure('stere_rgb.png', [1,2,3], clim='hist')

Tests

Nansat is outfitted with unittests, which you can use to ensure that all functionality works on your platform.

::

# install testing packages from conda-forge
conda install -c conda-forge nose mock

# run nansat.tests
nosetests nansat

# Run all tests including nansat_integration_tests with coverage
cd <nansat_repository_folder>
nosetests -w . --with-coverage --cover-package=nansat

Nansat works on both Python 2 and Python 3 but automatic testing on TravisCI is done for Python 3.7 only. Fore more information see Read the Docs_ or notebooks for Nansat lectures <https://github.com/nansencenter/nansat-lectures/tree/master/notebooks>__
