Hi Markus,

Excellent, thank you for the tip!

Note I tried again using r.patch.many with a smaller batch last night (333 billion pixel mosiac) and it ran *much* better, but I think it is stuck now.

Here is a screen shot when it was cranking away:

The “Bytes Read” has been going up continuously for the r.patch processes, but the bytes written hasn’t changed in over 8 hours and appears stuck at 57%. I think I can use r.patch.many for the job but I will have to break it into smaller sub-mosiacs first.

If I understand importing a virtual mosaic correctly, I suspect using r.external with a virtual mosaic is the best way to accomplish the task at hand, but I welcome any advice!
