Raster Generalization - Expand, Shrink - not working

[BobChristensen]

Hi, I am trying to use the raster generalization tools "expand" and "shrink" but the operation fails. I have been successfully using the majority filter tool on the same data in the same project. Here is an example message from the failed expand process:

Please help.

Did you actually go into the Environments tab in the tools you are using and set your scratch workspace there?  I would set them to real (my term) folders that are short.  Apparently you are working in a restricted environment so I can't comment on your setup, but in my teaching labs, we have a 'users is for losers' motto that when you set all workspaces to local drives, then the problems are fewer.  This is one of the first questions I ask about workspaces... what is your working folder and what is your scratch folder.  If they aren't set, then they need to be ruled out.  Let me know if that works.  (ps  what is the ~ tilde in your folder path? is that real or a contraction of the true path?)

Hi Dan, 

I tried running a few more times with different scratch and workspace settings. I attached a shot of the latest settings and copied the error below.

weird... your scratch say c:\WORKSP~1\... which looks ok... then I look at the image and it is wickedly speckled.  I suspect that you haven't got a prayer of doing an expand shrink on that file without a light dusting of a 3x3 majority filter to get rid of the single and double cell regions.  try that... if that fails, clip out an area and see if it works on a smaller sample.... if that doesn't work.. try PRO
