This question already has an answer here:
Embarrassed that I haven't looked at this for some time (can't quite get the syntax down). (ArcGIS 10.2, Win7x64).
Within Map Algebra (Raster Calculator) Trying to add the cell values of 3 rasters, each raster has multiple fields. Trying to add: SumRaster = (Raster1, Field X)+ (Raster2, FieldY)+ (Raster3, FieldZ).
Can get to run (using primary VALUE field from each), want to specify FIELD value to SUM.
Alternately would be OK to export each Raster, setting my desired VALUE from this specified Field (and don't remember how to do this in 10.2).
Any help with Syntax would be great.
