Can someone please elaborate the difference between ENVISAT ASAR Wide Swath (WS) data and ASAR Alternating Polarization (AP) data such as HV or VH when they are used for vegetation monitoring for the region of interest?
HV or VH gives good results in vegetation as vegetation is more sensitivite to VH or HV compared to same polarisation of VV or HH. resolution is also different. WS doesnt give HV or VH, so it cannot be used for vegetation studeis though they are good for urban or flood monitoring.But becoz of the resolution constrain WS is also not used for urban areas widely.WS is mainly used for oceanic studies.
