I have a land use layer which includes 36 different individual classes. Using the raster calculator I have been able to extract 1 of the different classes and make a new layer (landuse=[number of the land use class]). I want to put multiple of these classes together to create one layer e.g. a general forest layer, and tried using the AND function. This however is not working and only acknowledges the first number in the equation (e.g. landuse = 1 AND 2 AND 3) only the land use equivalent to 1 is produced. Does anyone have any ideas?
