Dear all,
I want to do classification over sea ice but I have one big island in my Tandem-x image.
I also have island shape files. I opened it in QGIS. You can see it below.
When trying to perform an extract by mask command I can successfully get this operation to work. My question is can the areas outside the Area of interest of the polygon be assigned a Invalid pixel value. As when trying to create an interferogram if the the master and slave image were both masked areas it would significantly reduce the lenght of time it would take to complete this graph.
