Hi I am trying to bulid a python tool in which the user will import a DEM and that tool will reclassify it in 3 classes, for maxheight-10, maxheight-20 & maxheight-30 meters to use it for other process. I have created that code but I always get an error that RemapRange is not defined. Why is that? I am using ArcGIS 10.2.2
# Import system modules import arcpy # Set environment settings inWorkspace = arcpy.GetParameterAsText(0) inDEM = arcpy.GetParameterAsText(1) outDEM = arcpy.GetParameterAsText(2) # Get Raster Properties maxvalue = arcpy.GetRasterProperties_management(inDEM, "MAXIMUM") minvalue = arcpy.GetRasterProperties_management(inDEM, "MINIMUM") minvalue2 = (minvalue.getOutput(0)) maxvalue2 = (maxvalue.getOutput(0)) # Conversion of max value to integer intmaxvalue = int(float(maxvalue.getOutput(0))) # Creation of classes per 10 meters until intmaxvalue-30 meters class1 = intmaxvalue - 10 class2 = intmaxvalue - 20 class3 = intmaxvalue - 30 #Reclass DEM reclassfield = "Value" myRemapRange = RemapRange([[minvalue, class3, 4], [class3, class2, 3], [class2, class1, 2], [class1, maxvalue2, 1]]) outReclass = Reclassify(inDEM, reclassfield, myRemapRange) outReclass.save(outDEM)
Solved! Go to Solution.
RemapRange—Spatial Analyst module | ArcGIS for Desktop shows how to deal with nodata values, it will always be a separate class
There are 3 numbers in the range you appear to have 2 RemapRange—Help | ArcGIS for Desktop
I tried that also, and I have the same error
print out the remaprange so people can see the output without having to do it themselves
Traceback (most recent call last):
File "C:\Users\KOSTAS\Desktop\code.py", line 25, in <module>
myRemapRange = RemapRange([[minvalue, class3, 4], [class3, class2, 3], [class2, class1, 2], [class1, maxvalue2, 1]])
NameError: name 'RemapRange' is not defined
Failed to execute (MAXIMUMViewshedAnalysis)
This is the message
Oh and check the 2nd code example, you need to import sa
from arcpy.sa import *
Of course.. Now it succeded but it doesn't appear anywhere. At the parameters of the tool I have put the inDEM as Raster Layer/ Input and outDEM as Raster Layer/ Output. I don't see the problem
Well, I can't tell since I don't know what the output dem filename is and whether you have your environments set to add the results automatically to disk, or whether you are running the script with arcmap running, or whether you are using an external python ide or the one built into arcmap. More details are needed and print statements would help those on this site narrow down the problems you are having.
Excellent. The only problem is that I have a value that is propably is NO DATA and it appears separate from the classes. How can i fix that.
