UPdate to use MOMA3. translate old map algebra syntax into new Map Algebra using arcpy in scripting or the new Raster calculator.for example9.3:out = gp.SingleOutputMapAlgebra( "EXP(-7.48097564815 + SUM(ras01,ras02,ras03))","outRaster")10:out = EXP(-7.48097564815 +(ras01 + ras02 + ras03)) #(Note: ras0n = raster object)out.save("outRaster")
