Spatial Analyst - Focal Statistics - No output?

ChrisMan — Thu, 17 Aug 2017 18:36:38 GMT

I'm running a simple analysis of a raster layer containing discrete elevation values, using the Focal Statistics tool from within the Spatial Analyst toolbox.

Each time I have run the tool it returns no results, I have checked through the environment variables and selected different options within 'Focal Statistics' however the output is still empty.

I have the results saved (and hopefully attached).

Any help appreciated, I am hoping I'm tired and I've made a simple mistake.

could you post a screen grab or copy of the inputs and the environments.. the zip's rlt can't be read

Chris,

This kind of looks like ArcMap, not ArcGIS Pro.

What does your results window indicate? Using the Results window—Help | ArcGIS for Desktop

it's not going to like that output folder.. it has dashes and a plus (-, +)... try c:\mystuff\fstats.tif

Also I see that you are working in a Personal Geodatabase (.mdb), which has a storage limitation of < 2 GB.

Try working (or saving the output) in a File Geodatabase (.gdb) or a basic folder for storing the output raster.

Yes this is ArcMap.

My results window is the first image, I can't see any issue with what I see on there, in terms of input.

My output shouldn't exceed 2Gb but thank you, I'll keep that in mind.

Edit:

When I changed the output to a File geodatabase with a *.tif output format it ran perfectly.

Is this because the personal geodatabase cannot handle output format being created?

I've changed the filepaths and folder names removing the operator characters and spaces.

I've taken your input but unfortunately my output/result is still similar.

Any further ideas greatly appreciated.

You are still using an mdb. export the inputs into a simple folder and use that folder for the inputs and the outputs. The file source and destination may be the issue. Use a file geodatabase rather than a personal geodatabase at least. again c:\test as the folder for the source and destination and try the output as a *.tif

And I assume inputs are in the same coordinate system!?

(Dan - yes the inputs are both the same projection)

Many thanks to you all, resolved now.

I shortened the file path, the problem still occurred.

When I changed the output to a File geodatabase with a *.tif output format it ran perfectly.

One question - is this because the personal geodatabase cannot handle the required output format?

Chris... As I said in your other post.. haven't use a personal geodatabase in years. *tif is now the recommended raster format and either use a folder or a file geodatabase as you go forward
