The issues I keep seeing depend on unique combinations of values.
I have three rocktype raster layers for area and they are edge-to-edge (they do not overlap). They each have "VALUE" fields and "COUNT" fields. There's one row of data for each attribute table where "VALUE"=1 where the rock type exists. I guess this is like mask.
What I need to do is combine these three rasters into one with raster calculator using this logic.
rocktype1==1, output value=1
rocktype2==1, output value=2
rocktype3==1, output value=3
Here's what I've tried:
Con("rocktype2"==1, 2) | Con("rocktype1"==1, 1) | Con("rocktype3"==1, 3)
Con("paleo"==1, 2, Con("precamb"==1, 1, Con("tert_quat"==1, 3)))
Combine(["rocktype2","rocktype1","rocktype3"])
rocktype1 + rocktype2 + rocktype3
I continuously get a blank output raster. What am I doing wrong here?
I'm using ArcMap 10.3.
