I am attempting to create H/alpha plane plots for a number of RADARSAT-2 quad pol datasets. My initial workflow is as follows:
read >> radiometric calibration >> polarimetric speckle filter >> polarimetric decomposition >> terrain correction >> write
…however, I have noticed that in the batch processing tool in SNAP there is the option to run a H-a Alpha classification which includes the following step:
read >> calibration >> polarimetric matrices >> polarimetric speckle filter >> polarimetric classification >> write
My first question is, are these 2 models different? I understand one is the decomposition and the other a classification but both are generating an H-a Alpha dataset. My second question is, if they are similar, do I need to include the polarimetric matrices in my initial workflow? My final question, can you provide insight into the matrix generation?
