A python based QGIS plugin
This plugin generates derived SAR parameters (viz. vegetation indices, polarimetric decomposition parameters) from input polarimetric matrix (C3, T3, C2, T2). The input data needs to be in PolSARpro/ENVI format (*.bin and *.hdr). It requires numpy, matplotlib python libraries pre-installed.
Indices
- Radar Vegetation Index (RVI) (Full-pol and dual-pol)
- Generalized volume Radar Vegetation Index (GRVI)
- Polarimetric Radar Vegetation Index (PRVI) (Full-pol and dual-pol)
- Dual-pol Radar Vegetation Index (DpRVI)
- Degree of Polarization (DOP) (Full-pol, dual-pol, and compact-pol)
- Compact-pol Radar Vegetation Index (CpRVI)
Polarimetric Decompositions
- Model free 3-Component decomposition for full-pol data (MF3CF).
- Model free 3-Component decomposition for compact-pol data (MF3CC)
- Improved S-Omega decomposition for compact-pol data (iS-Omega)
