[GRASSLIST:2217] How to make mosaic of the raster files?

[Zbigniew Perski]

Hi everybody,

I have 6 scanned maps which was resampled into one project. The maps are 
  overlapping a bit and the scans includes also parts outside the map 
frame. Unfortunately after resampling to the project the mas are not 
rectangular. I would like cut out unwanted parts and mosaic the pieces 
into one file using r.patch. I have tried r.mask but it is masking out 
map values but not map areas. Is there any method in grass how to do it?


Thanks in advance.

Regards

Zbigniew
