I have two rasters that I wish to combine to give a third raster that describes spatially where multiple conditions of both rasters are met. For example, say my two input rasters are raster A and raster B. Values like this:
X1 X2 X3 Y1 A1 A2 A2 Y2 A1 A1 A1 Y3 A1 A1 A2
X1 X2 X3 Y1 B1 B1 B1 Y2 B1 B1 B1 Y3 B1 B1 B1
I want to create a third raster with different values that occur where conditions from both are met, see the below "psuedo-code" describing what I want:
WHERE (RASTERA = A1 AND RASTERB = B1) THEN ALPHA WHERE (RASTERA = A2 AND RASTERB = B1) THEN BETA
Giving my final raster as below:
X1 X2 X3 Y1 ALPHA BETA BETA Y2 ALPHA ALPHA ALPHA Y3 ALPHA ALPHA BETA
How can I accomplish this, preferably using raster calculator?
P.S. In my real data, I have numbers that I need to be in certain ranges. As such I could not simply concatenate the raster values (e.g. A1, and B1 to give A1B1) and give an alias fitting to that.
