I am trying to reclassify a raster, using arcpy in Python. My code is below

from osgeo import gdal
import arcpy
from arcpy import env
from arcpy.sa import *

raster_file = 'M:/tgopalakrishna\Data\CONUS_def_001_in_020\CONUS_def_001_in_020.tif'

#Opening the raster file
dataset = gdal.Open(raster_file)
band = dataset.GetRasterBand(1)
print band

#Reading the raster properties
projectionfrom = dataset.GetProjection()
print projectionfrom
geotransform = dataset.GetGeoTransform()
print geotransform

block_sizes = band.GetBlockSize()
x_block_size = block_sizes[0]
print x_block_size
y_block_size = block_sizes[1]
print y_block_size

xsize = band.XSize
print xsize
ysize = band.YSize
print ysize

max_value = band.GetMaximum()
print max_value
min_value = band.GetMinimum()
print min_value

stats= band.GetStatistics(0,1) 
print stats # prints min, max, mean and std

# Set local variables
reclassField = "VALUE"
remap = RemapRange([0,999,1])

# Check out the ArcGIS Spatial Analyst extension license

outReclassify = Reclassify(raster_file, reclassField, remap, "NODATA")


The errors I get are

Traceback (most recent call last): File "*************trial.py", line 41, in remap = RemapRange([0,999,1])

File "D:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\sa\ParameterClasses.py", line 1160, in init _Remap.init(self, remapTable)

File "D:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\sa\ParameterClasses.py", line 1129, in init self.remapTable = [list(record) for record in remapTable]

TypeError: 'int' object is not iterable

So clearly, there is something wrong with the range of the reclassification. How do I solve this?

I think you might need double brackets here:

remap = RemapRange([[0,999,1]])

Because RemapRange expects a list of lists for the remapTable parameter.

  • I think RemapRange requires spatial analyst - maybe check out the extension before hitting that method? – Jvhowube Aug 3 at 15:12
  • I have checked out the Spatial extension (see towards the end of script) – tg110 Aug 3 at 15:16
  • Right but do it before you run RemapRange, as scripting is linear. – Jvhowube Aug 3 at 15:21
  • DId not help. Same 99999 error. – tg110 Aug 3 at 15:28
  • Not sure, but what's going on with your crazy forward/back slashes in your paths? Shouldn't they all be backslashes? – Jvhowube Aug 3 at 15:40

I ultimately ended up using the Con tool with syntax

outRas= Con(Raster(raster_file)>0 & Raster(raster_file)<999,1,0)

Above worked.
