Raster Calculator in Arcpy

SoratoMarques — Tue, 28 Feb 2023 11:49:12 GMT

Hi,

I have 2 rasters in 2 differents locations. I need to use the raster calculator in arcpy like below:

Float(input_biomassa - std_tif)

I was exported the code from Model Builder, but no work properly.

Someone can help me?

Thank´s

showing the modelbuilder export code would help

otherwise look at

paying attention to cell cize,alignment and extent if you want expected results

I´m using Arcmap, below the code:

arcpy.gp.RasterCalculator_sa("Float(input_biomassa - std_tif)", negativo_tif)

I was tried your suggests already, but no work too.

Float("input_biomassa" - "std_tif"), "negativo_tif")

would be the case in Pro... the raster names are in " " not as you have it
