Bug report #15492

Updated by Alexander Bruy almost 4 years ago

I was trying to clip dem by watersheds.

It was same process as below.



http://docs.qgis.org/2.2/ja/docs/training_manual/processing/iterative.html



But it doesn't work when it iterates.

Without iteration, I could clip my data.

I made sure that polygon(watersheds) and raster(dem) have same CRS.



I think this function is very useful for everyone.

Please give me some idea to fix this problem.
