I can't force Python raster calculator to sum the rasters
by
Hi, Im newbie two Python scripting at all, anyway.
I'm trying to sum two rasters in Python toolbox, but it doesn't work the way I want it to. Here's the code:
import arcpy
from arcpy import env
from arcpy.sa import *
class Toolbox(object):
def __init__(self):
"""Define the toolbox (the name of the toolbox is the name of the
.pyt file)."""
self.label = "Toolbox"
self.alias = ""
# List of tool classes associated with this toolbox
self.tools = [Tool]
class Tool(object):
def __init__(self):
"""Define the tool (tool name is the name of the class)."""
self.label = "Tool"
self.description = ""
self.canRunInBackground = False
def getParameterInfo(self):
"""Define parameter definitions"""
param0 = arcpy.Parameter(displayName="Input Features", name="in_features", datatype="DERasterDataset", parameterType="Required", direction="Input", multiValue = True)
params = [param0]
return params
def isLicensed(self):
"""Set whether tool is licensed to execute."""
return True
def updateParameters(self, parameters):
"""Modify the values and properties of parameters before internal
validation is performed. This method is called whenever a parameter
has been changed."""
return
def updateMessages(self, parameters):
"""Modify the messages created by internal validation for each tool
parameter. This method is called after internal validation."""
return
def execute(self, parameters, messages):
# Set environment settings
env.workspace = "C:/temp"
#Set local variables
inRaster = parameters[0].valueAsText
rasters = inRaster.split(';')
# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")
#Execute sum
output = Raster(rasters[0]) + Raster(rasters[1])
#Save the output
output.save("C:/temp/result/output02")
returnI have two different 0-1 rasters in the same region created from different buffers. I expected it sums for each pixels it values, when on the same pixels i need it to give two when both pixels are black, one when when one of them is black and 0 when both are 0. But it just gives me nearly the same raster as the first. What do I do wrong? I expect it to work this way:
Here're the results I get, at first look the result's streams are not continous, but due to the image it should be:
