ESRI grid and "info" folder inside the working directory

Hi Guys,

I have a silly question to ask. Using the below code, I want to extract a new raster from an original raster using value field and I want to automate the process for 70 more rasters. However, for testing purpose, I 'm using only 3 rasters.

Out of 3 rasters inside the working directory, this code works only for one raster which has both " ESRI grid" and "info" folder inside the working directory. I was not able to keep the "info" folders of other two raster inside the working directory as the "info" folder of 1st raster is already in the working directory.

I know it is stupid question. But could you please let me know how can i keep the "info" folders of other two rasters inside the working directory, so that code will work and I can automate the process?

Thank you very much for your time and help!

Code:

import arcpy,os

from arcpy import env

from arcpy.sa import *

#To overwrite output

arcpy.env.overwriteOutput = True

#Set environment settings

env.workspace = "C:/Subhasis/Test/Neshanic_Python"

outws="C:/Subhasis/Test/Neshanic_Python/extract"

#checkout ArcGIS spatial analyst extension license

arcpy.CheckOutExtension("Spatial")

# create a list of all rasters in current workspace

lst_ras = arcpy.ListRasters()

threshold = 0.75

for ras in lst_ras:

flds = ("VALUE", "COUNT")

dct = {row[0]:row[1] for row in arcpy.da.SearchCursor(ras, flds)}

sumcnt = sum(dct.values())

threscnt = sumcnt * threshold

cnt, result = 0, 0

for k in sorted(dct):

cnt += dct

# print " - Value = {0}, Sum = {1}".format(k, cnt)

if cnt < threscnt:

result = int(k)

else:

break

print "Threshold = {0}".format(result)

attExtract = ExtractByAttributes(ras, "VALUE>={0}".format(result))

outname = os.path.join(outws,"{0}{1}".format(ras, result))

attExtract.save(outname)

arcpy.CheckInExtension("Spatial")

In short, there is only one info folder per folder. For example, 10 grids in a folder will all share the same info folder. If you want separate info folder for each grid, then you have to copy/export (not using your operating system!!!) each grid to its own folder
