Modelbuilder - Clip multiple rasters not working

RichardPearson_org — Tue, 18 Nov 2025 11:12:25 GMT

Hi folks, I wonder if anyone else is experiencing a weird modelbuilder error around interators and clipping rasters?

I have an existing model I've used before, which I modified to work on a new set of rasters. The workflow is to take a raster tile and clip it using a 5km square polygon, then do the same for a further 5 rasters, each with a matching polygon. I iterate through the 6 polygons, using the text string in one of the fields to define the %Name% variable, which I then use to select the matching tif file for each polygon. That's how it used to work, anyway. Now, the model fails before the clipping stage with the following error:

If I manually select one of the tif files as the raster to be clipped, the model works perfectly for that tile, but if I use the %Name% variable to define the exact same file name and path, the model fails.

If I modify the model slightly to clip one large raster into 6 individual tif files using the 6 polygons, rather than clipping 6 separate rasters, the model again works perfectly!

Just seems really odd. Any advice gratefully received....

Many thanks

Richard
