I have two rasters and am using QGIS 3.6
I want to know which areas in raster 1 that are "no data" are not "no data" in raster 2.
I also want to know what areas in raster 2 that are "no data" are not "no data" in raster 1.
I assume that the QGIS raster calculator is the tool to use. I dont think there is a way to use conditional statements and I am unsure how to enter No data into it.
