Problem: Feature to Raster converstion using python scipt

ZiaAhmed

I am trying to convert a shape file to raster by a python script. But it did not work. However, this conversion was done successfully by ArcToolBox. I used similar parmeters for raster conversion in the script - but I have got following errors. Any idea?

# print arcpy.GetMessages

Traceback (most recent call last):
File "K:\SCRIPT\Python_Script\ShapeToRaster.py", line 22, in <module>
arcpy.FeatureToRaster_conversion(inFeatures, field, outRaster, cellSize)
File "C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy\arcpy\conversion.py", line 1686, in FeatureToRaster
raise e

ERROR 000860: Input features: is not the type of Composite Geodataset, or does not exist.

Hello, I got the same Error recently. But my problem is some about raster not shapefile.And finally I work it out by the key of datatype. For example I want to use "GreaterThanEqual" in my model, so I create a variable with the default datatype "Raster Dataset" and when I use my tool in code, I got the error like this,

arcgisscripting.ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000860: Input raster or constant value 1: is not the type of Composite Geodataset, or does not exist.
ERROR 000860: Input raster or constant value 1: is not the type of Composite Geodataset, or does not exist.
Failed to execute (Model3).

And while I change the datatype from "Raster Dataset" into "Raster Layer" , my code ,the same code, works well.

So I think we can do something by the Datatype.
Further, to my surprise, when I change the datatype from "Raster Layer" back to "Raster Dataset", my code still work.
I am confused. I am not sure,but my code could work.

May you succeed.

Following script works well for this example (Indiana) and as well for other States. This script was imported from Model Builder. Thanks Zia

# Import arcpy module
import arcpy

# Local variables:
soilmu_in= "K:\\STATE_ MUKEY\\AREA.gdb\\soilmu_in"
soilmu_in__2_ = "K:\\STATE_ MUKEY\\RASTER.gdb\\soilmu_in"

# Process: Polygon to Raster
arcpy.PolygonToRaster_conversion(soilmu_in, "MUKEY", soilmu_in__2_, "CELL_CENTER", "NONE", "90")
print arcpy.GetMessages

Your code specified you shape file in "K:/STATE_MUKEY/AREA.gdb", which is obviously wrong. You should specify the full path of your shape file (wherever that is). like this
inFeature = "K:/STATE_MUKEY/soilmu_in.shp"

Thanks your reply. These is exist! Please see the attachment. I mentioned before, I converted this file to raster using ArcTool box.

After changing to feature class, it shows similar error.
Thanks

hzhu is correct. You are specifying a shapefile rather than a feature class. Change:
inFeature = "soilmu_in.shp"
to
inFeature = "soilmu_in"

inFeature = "soilmu_in.shp"

inFeature = "soilmu_in"

You set up arcpy.env.workspace = "K:/STATE_MUKEY/AREA.gdb" and inFeature = "soilmu_in.shp". Basically you are telling arcpy to find soilmu_in.shp in K:/STATE_MUKEY/AREA.gdb, which does not exist.
