How do I get set up?

To avoid problems with installation, use of the virtualenv Python virtual environment is recommended.

Then use pip to install all dependencies (numpy, scipy, matplotlib, netCDF4, ...), e.g.:

pip install numpy scipy netCDF4 matplotlib opencv-python pyyaml pint polygon3

Then run the following to install the eddy tracker:

python setup.py install

Tools gallery

Several examples based on py eddy tracker module are here.

Quick use

EddyId share/nrt_global_allsat_phy_l4_20190223_20190226.nc 20190223 adt ugos vgos longitude latitude ./ -v INFO

for identification, followed by:

EddyTracking tracking.yaml

for tracking (Edit the corresponding yaml files and then run the code).
