I'm trying yo execute the RastertoPolygon conversion tool in ArcGIs 10.1. I'm executing it through a for loop, then it resulted to an error (Unable to open feature class Failed to execute (RasterToPolygon)) at the python console. As I checked for some output, the first raster from the list is successfully converted to shp file while the rest are not. Any suggestions? Note: (All of my rasters are already in integer data type)
#import the module
from arcpy.sa import *
from arcpy import env
env.overwriteOutput = True
#set the workspace
arcpy.env.workspace = r"C:\Users\Windows\Documents\JO_GIS_Analyst"
#Get a list of rasters and convert to shapefile
for raster in arcpy.ListRasters("nofpt*", "TIF"):
print raster #check the presence of rasters"
#convert the raster to polygon
arcpy.RasterToPolygon_conversion(raster, raster +".shp", "SIMPLIFY")
print "Finish converting the rasters to polygon"
