I have 4 raster datasets of the same extent. I would like to create a new  dataset so the where 1 dataset occurs I have a value of 1 in the new dataset where 2 datasets occcur together I have a value of 2 etc. I am essentially just adding the 4 datasets together and scoring them depending on whether they occur on top of one another.
Is there a simple way of doing this?
Any help appreciated.
