I want to clip the elevation data (3DEM) downloaded from USGS website. The raster-clip tool "Clip (data management)" in ArcGIS Pro works very well. However, I cannot clip it using the python function "arcpy.Clip_management()" .

The error report that the raster file is not exist or not support. I have tried different ways to read it, such as:

~grdn39w075.tif/Band_1 This is used by the Clip tool in Arcgis Pro ~grdn39w075.tif_Band_1 ~grdn39w075/Band_1

None of them can read the 3DEM file successfully.

Python code:

in_raster= "C:/Users/Desktop/Elevation/Tiles/grdn42w075.tif/Band_1"
for i in range(0,9):
 buffer = shp_list[i]
 out_id=num_buffer=re.findall('\d+', shp_list[i])
 arcpy.Clip_management(in_raster,buffer,"n42w75_"+ out_id[1],
"C:/Users/Desktop/Documents/ArcGIS/Projects/LUR/LUR.gdb","99999","ClippingGeometry", "MAINTAIN_EXTENT")
  • ~/ means nothing in Windows, try using the full path including the drive letter

  • Sorry about the confusion. I use the full path in my code. To protect the ID credential in our school, I use ~ to represent the first part of path.

  • Ah, gotcha. To debug, print your output file path that you're building and make sure that looks valid. Try arcpy.Exists() on the input file to make sure that's getting found correctly

  • I suggest deleting '~' and replacing it with some dummy pseudonym like C:/Users/SomeUser/, for clarity to other readers. Jan 31, 2019 at 5:18

I think the problem is here:


A .tif file, on the OS, is the end of a path, so /Band_1 doesn't make sense when Python tries to look for that path. If you're just going for that .tif file, simply delete /Band_1. All existing bands in the GeoTiff should get clipped by default by the Arc tool.

If grdn42w075.tif is in fact a directory, you might need to supply the file extension for the file Band_1. I suggest not naming your directories that way, and please use 4 spaces when indenting in Python :)
