I have five rasters with values between 0.1-1 and null values everywhere else. The values on the rasters overlap in some areas, but not everywhere (i.e. two rasters may have a value while the other three are null at a given xy). I want to be able to sum all of the rasters together without ending up with a null value. For example, at a given xy location three of the rasters have a 1 and the other two rasters are null. When I add them together I want a resulting raster with a value of 3 and not null. I think I need to convert the null values to zeroes, but maybe there is an easier way. What's the best way to do this?
Thanks that was really easy. For some reason it clipped the output raster to some random small extent, but then I included a zero raster that covered the entire area and that fixed the clipping problem.
