Split raster - use model builder or write Python script?

CorinnaNeeb — Sun, 19 Sep 2010 16:56:59 GMT

I have tiled orthophotos for my county that need to be split into smaller tiles. The "split raster" tool in ArcGIS 10 works wonderful but I would like to automate this process so that I don't have to manually repeat the input for each and every current tile for the county. I got to thinking, this may be a candidate to either create a model in model builder or write a Python script. I'm a newbie to all of this so any help would be appreciated.

Here's more details of what I would like:

I have a file folder with 198 tiles that need to be split into 3 tiles in the X direction and 3 in the Y direction (broken into 9 tiles)
The desired output file type is JPG

Thanks in advance,
Corinna

I actually just wrote a python script to do just that (see attached).... basically you point the script to the directory containing your raster data (workspace) and it then it splits each one up.

How would you add this to the middle of a model, I have one tool that just will not process my file - however if I split the file process Region Group on the smaller files, then put them back together it is fine. However I need to have this in a model and I do not see how to get the output files from split raster into the next step b/c the output from split raster is a location.
