arcpy.Resample_management() syntax

BenLeslie1

What's the correct syntax for using the path of a raster dataset to set the output cell size as mentioned, but not explained, in the help docs?

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

I get "ERROR 000628: Cannot set input into parameter cell_size"

p.s. I know there are ways round this using GetRasterProperties etc but would like to know how to do it this way.

Thanks

Thanks, but that doesn't answer my question, I'd like to know the correct syntax for inputting the raster path; I have tried many variations, including your sugesstions, all without success such as:

using the env.workspace setting to set the path and then defining the raster file name

typing the full path using raw notation

typing the full path using forward slash notation

using single quotes

using double and single quotes

using single and double quotes

using triple double quotes

using double double quotes

setting the raster as a layer and using that

typing it as it appears in the GUI i.e. "Same as layer ............"

I'm beginning to suspect that the tool doesn't do what the help docs says it does.

As I said, I know there are other ways of doing this but I'm just a firm believer the help docs should:

1. Help

2. Reflect how the program works

If you don't want to use a number, then you have to specify the full path to a raster with the cell size you want. It is best to use raw notation or use forward slashes in the path name.

I don't think that answers my question, I want to set the cell size using the 'third way' as highlighted in bold in the extract from the help docs below:

You can specify the cell size in 3 different ways:

Using a single number specifying a square cell size
Using two numbers that specify the X and Y cell size, which is space delimited
Using the path of a raster dataset from which the square cell size will be imported

arcpy.Resample_management("image.tif", "resample.tif", "10", "CUBIC")

where the cell size in in the units of the data, not what you want them to be
