Hi all,
I am currently working on a land use classification using a multitemporal dataset. I have stacked the 4 different raster layers in QGIS originating from 4 different dates. My problem is that I don´t know how I can put a NaN value to all 4 layers, if there was an NaN value for 2 or more dates in the scene.
I tried using the band math tool but I am quite new to snap and not sure about the expression. I would also appreciate other solution suggestions.
Thanks a lot in advance
