[GRASSLIST:6752] batch; clip raster map

[Axel Orth]

hey list,
due to your help georeferencing the scanned maps and exporting them as 
tif with world file works now.
thank you.

I hope you can help me with this next two questions too.

#1
As the scans are quite big i.rectify and r.out.tif take a long time to 
perform their tasks.
So i like to know if there is a way to run this in a batch job so i can 
do all the preprocessing for he several scans and let a batch job run 
over night to rectify and export everything.
I have never used batch before so if it is possible i need advice how to 
write this batch file.

#2
The scanned maps contain information for a municipality whose border is 
available as shape file. Is there a way to “clip” the raster map with 
this shape file so that the outline of the raster map equals the border?

Cheers
Axel
