Interpolating with IDW(geostatistical analyst): Python for Loop

KevinAchieng

Hi All,

I'm trying to interpolate point feature classes with Python.  I would like the output to maintain the name of the input feature class.

However, my code seem not to be running.

Please assist me troubleshoot the code:

Thanks in advance.

Please see below

# Import system modules

import arcpy

from arcpy import env

# Set environment settings

arcpy.env.workspace = r"\\bsedom5\users\kachieng2\Desktop\ET_2002-2014\Product\Monthly"

fclist=arcpy.ListFeatureClasses()

arcpy.env.overwriteOutput="True"

# Set local variables

inPointFeatures = "fc"

zField = "ETommd"

outLayer = "outIDW"

outRaster = r"\\bsedom5\users\kachieng2\Desktop\ET_2002-2014\Product\MonthlyET.gdb\fc"

cellSize = 2000.0

power = 2

# Set variables for search neighborhood

majSemiaxis = 300000

minSemiaxis = 300000

angle = 0

maxNeighbors = 15

minNeighbors = 10

sectorType = "ONE_SECTOR"

searchNeighbourhood = arcpy.SearchNeighborhoodStandard(majSemiaxis, minSemiaxis,

                                                       angle, maxNeighbors,

                                                       minNeighbors, sectorType)

# Check out the ArcGIS Geostatistical Analyst extension license

arcpy.CheckOutExtension("GeoStats")

# Execute IDW

for fc in fclist:

    outRaster = r"\\bsedom5\users\kachieng2\Desktop\ET_2002-2014\Product\MonthlyET.gdb\fc[:-4]"

    arcpy.IDW_ga(fc, zField, "", outRaster, cellSize, power, searchNeighbourhood)

Also, your path to outRaster will not work as you expect. By leaving the variable fc[:-4] inside the quotes, it literally becomes part of the string (e.g. "...\Product\MonthlyET.gdb\fc[:-4]").

Instead, use the os module's path.join method to join your base path to the variable:

>>> fc = "someraster2014"
>>> import os
>>> outRaster = os.path.join(r"\\bsedom5\users\kachieng2\Desktop\ET_2002-2014\Product\MonthlyET.gdb",fc[:-4])
>>> print outRaster
\\bsedom5\users\kachieng2\Desktop\ET_2002-2014\Product\MonthlyET.gdb\someraster
