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? If anyone has any other advice in how to approach this I appreciate suggestions.
thanks
