text: Dear Arcpy Users,
  I am reclassifying my raster data but I cannot get the output that I want. The case is, I have a floating point raster, in which, I want to reclassify it into categorical values. It is quite weird that some of my values are reclassified outside the range of values that I set. For instance,
  output categorical raster original raster
  1 1.24941356103
  1 0.944287159553
  1 0.70514940818
  0 0.0177492300117
  0 2.72532446104e-07
  250 -6.0889773748
  This is the reclassification method that I want to do.
  -50 to -2.58 = 6
  -2.58 to -1.96 = 5
  -1.96 to -1.65 = 4
  -1.65 to -1.29 = 3
  -1.29 to 2.58 = 2
  2.58 to 50 = 1
  other pixels = No data
  Here is the code that I am running.
  import arcpy, os, sys from arcpy import env from arcpy.sa import * arcpy.env.overwriteOutput = True arcpy.CheckOutExtension("Spatial") arcpy.env.extent = "MAXOF" arcpy.env.workspace = r'directory\of\rasters\test' rasters = arcpy.ListRasters("*","TIF") out_ws = 'output/directory/Reclass/' if not os.path.exists(out_ws): os.makedirs(out_ws) for raster in rasters: name, ext = raster.split(".") fileout = out_ws + name + "_reclass" + ".tif" outReclass = Reclassify(raster, "Value", RemapRange([[-50.0,-2.58,6],[-2.58,-1.96,5],\ [-1.96,-1.65,4],[-1.65,-1.29,3],[-1.29,2.58,2],[2.58,50.0,1]]),"NODATA") outReclass.save(fileout)
  looks fine, but try removing the \ at the end of the first line in your RemapRange list, it is
  nt needed or wanted
