I am using QGIS 3.10 and try to solve the following task. I have a multiband raster (4 bands in total), where each band represents the spatial extent of a tropical storm and the respective pixel value represents the wind speed.
In other words, the multiband raster contains all tropical storms within a given area for a respective year. In this case there have been 4 tropical storms, represented by the 4 bands. Now I want to create a singleband raster containing the max value of the 4 rasters, so that the new singleband raster image contains the maximum wind speed exposure for cell i in year t. If a cell was hit by two storms, I want to assign the value of the band with the higher wind speed.
The question in short is: How do I tell QGIS to compare the raster values of all bands and then choose the highest one. I tried the raster calculator, but I could not figure out a suitable option and I am not really familiar with the syntax in the raster calcaaltor.
