Hello,

 

I'm trying to do the exact same thing for 25, 50, and 75 percentiles.  I have an integer DEM and a set of continuous polygons.  Here is the error I'm getting:

 

 

Traceback (most recent call last):

 

  File "C:\Python27\ArcGIS10.3\Lib\percentiles.py", line 100, in <module>

 

    pixval =  GetPixelValueForPercentile(dct_per, perc_dec)

 

  File "C:\Python27\ArcGIS10.3\Lib\percentiles.py", line 10, in GetPixelValueForPercentile

 

    return pix_val

 

UnboundLocalError: local variable 'pix_val' referenced before assignment

 

I am not a python programmer, any insight is most appreciated.  I've attached the script with the changes I made, which were only the list of percentiles (line 25) and the paths to my datasets.  Ideally, if it's possible, I would like to run this on a float raster instead of an integer raster.

Much thanks,

Brian
