I am working on creating a map of total chemical inputs into a study area. I have several raster layers of different inputs with values stored in the attribute tables. I am having a hard time figuring out how to add these inputs together. Is there a way in the raster calculator to add a specific field from the attribute table of each raster (these values are all decimals) and to ultimately display total chemical inputs spatially?
