Any help with the error message below would be appreciated. 

Thanks,

Can you double-check that you have the final slash on outrasterpath? If it's missing and not being concatenated properly, you could get an extension error:

import os
outrasterpath = r"S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdb"
featureClass = "featureClassName"
path1 = outrasterpath + featureClass
path2 = os.path.join(outrasterpath, featureClass)
print(path1)
print(path2)‍‍‍‍‍‍‍

S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdbfeatureClassName
S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdb/featureClassName‍‍‍‍‍‍‍‍‍‍

Try printing the following in the cursor:

print(outrasterpath, featureClass, outrasterpath + featureClass)‍

If you could share the entire script, that may expose more hints, too.

Darrin,

See my responses on GeoNet if you have not already.

Thanks,

Jim

I meant print that in your own script to ensure the values are exactly what you think they should be.

Darren,

Yes, using the actual pathnames gave the right results.  There may still be an issue with the extent of the polygon (outrasterpath + featureClass) that is being used to clip the ESRI grid.

Here's the latest on the processing.  There is a new line of code that captures the map extent of each:

coords = ("row[0].extent.XMin&" "& row[0].extent.YMin&" "& row[0].extent.XMax&" "& row[0].extent.YMax")

However, the following error is coming up after running the arcpy.management.Clip command.

arcpy.management.Clip(raster, coords, outrasterpath + featureClass, featureClass, "255", "ClippingGeometry", "MAINTAIN_EXTENT")

Traceback (most recent call last):

File "<string>", line 4, in <module>

retval = convertArcObjectToPythonObject(gp.Clip_management(*gp_fixargs((in_raster, rectangle, out_raster, in_template_dataset, nodata_value, clipping_geometry, maintain_clipping_extent), True)))

File "c:\program files\arcgis\pro\Resources\arcpy\arcpy\geoprocessing\_base.py", line 496, in <lambda>

return lambda *args: val(*gp_fixargs(args, True))

arcgisscripting.ExecuteError: ERROR 000964: Specified extent is invalidFailed to execute (Clip).

Sorry, but the option to paste into Python script format was not available.

This is the Python command copied from an interactive process for one record that processed correctly.

Maybe this will help?

I'll give that a shot.  Thanks all!

Darrin,

Here's the results of your script (which ran fine) and below is the whole script:

outrasterpath = r"S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdb"
featureClass = "featureClassName"
path1 = outrasterpath + featureClass
path1 = outrasterpath + featureClass
path2 = os.path.join(outrasterpath, featureClass)
print(path1)
S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdbfeatureClassName
print(path2)
S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdb\featureClassName
print(outrasterpath, featureClass, outrasterpath + featureClass)
S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdb featureClassName S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdbfeatureClassName
