My problem is that I would like to multiply two rasters using raster calculation tool. Both rasters have values 0 and 1, but the covered area of first raster is bigger (100 x 100 miles) then the area of second (80 x 80 miles). How can I extend the second raster to the same size? I would just like to add columns and rows with 0. At first I thought that this would be simple, but after searching on internet I didn't found any solution. :( Thank you in advance
