The toolkit provides useful python and bash scripts that use satellite imagery, particularly SAR and optical images, to monitor changes of glaciers and ice caps through time. The toolkit has two main approaches: ice elevation changes (also known as dh/dt) and pixel tracking.

dh/dt [v1.0]:

• python >= 3.0, with the following modules installed

  • numpy
  • scipy
  • matplotlib
  • shapely
  • gdal

• All scripts are pythonized, i.e. it should work fine on any Python-supported platforms (e.g. Windows, Linux).

pixel tracking [v1.0]:

• ISCE >= 2.0.0 (built with your python)
• python >= 3.0, with the following modules installed
  • numpy
  • scipy
  • gdal
  • geopandas
  • shapely

• Doc: Documentation
• Utilities: Subroutines and functions used by dh/dt and pixel-tracking main programs.
• dhdt: Main programs for dh/dt [v1.0]
  • dhdt.py: Main program
  • defaults.ini: template configuration file
  • Demo_DEMs: Demo input files
• pixeltrack: Main programs for pixel tracking [v1.0]
  • pixeltrack.py: main program
  • defaults.ini: template configuration file
  • Demo_Data: Demo input files

• dhdt/README.rst: [v1.0] dh/dt documentation
• pixeltrack/README.rst: [v1.0] pixel tracking documentation

The dh/dt [v1.0] and the pixel tracking [v1.0] is now being developed by Whyjay Zheng. Any suggestions/ideas would be really appreciated. Here's the reference to cite for dh/dt [v1.0]:

The dh/dt [v0.2] and the pixel tracking [v0.2] was developed by Whyjay Zheng, William J. Durkin, and Professor Matthew Pritchard, Cornell University.

The dh/dt [v0.1] and the pixel tracking [v0.1] was developed by Andrew K. Melkonian et al. Here is the reference to cite:
