MATLAB Codes for Geodesic Distance (GD) and its derived parameters across SAR Polarimetric Modes.

Three standalone MATLAB scripts in total:

1. CD_QP_simulated_modes_V2.m

Gedoesic Distance-Based Change Detection maps in various SAR polarimetric modes simulated from two coregistered Quad Polarimetric SAR dataset

2. pars_polm_V2.m

Three Gedoesic Distance-Based parameters in various SAR polarimetric modes simulated using Quad Polarimetric SAR data.

3. pars_S1_grd_V2.m

Gedoesic Distance-Based parameters for Sentinel-1 GRD images (Tested for sea ice in EW mode)

(Simply launch in MATLAB editor, read inset initial comments and run. 😃)
