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 published in Journal of Open Research Software in 2016.

The easiest way to install Nansat on any platform is to use Anaconda (download installer).

# install Nansat and requirements from the conda-forge channel
conda create -n py3nansat -c conda-forge nansat

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

# activate the py3nansat environment
source activate py3nansat

# start python and work with Nansat
python

# import main file opener
from nansat import Nansat

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

# see file content
print n

# view file footpring
n.write_map('stere.footpring.png')

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

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
