Tools to detect and track deformation features (leads and pressure ridges) in sea-ice deformation data.
A good description how to install python is given by N. Koldunov in: https://github.com/koldunovn/python_for_geosciences
After installing a miniconda you need to install to additional packages with:
conda install scipy.ndimage skimage
RGPS data in Lagrangian and Eulerian format need to be downloaded from Ron Kwok's homepage: https://rkwok.jpl.nasa.gov/radarsat/index.html
RGPS data needs to be unzip. The data needs to be orgnaized in a seperate directory for each winter that are named w9798, w9899, ...
Use gen_dataset.py to generate LKF data-sets, which performs three steps for each year:
- run the LKF detection on RGPS deformation data
- interpolate Lagrangian drift data to Eulerian grid
- run the LKF tracking algorithm
An in-depth description of the algorithm can be found here:
