[GRASS-user] question on georectification

[Wolfgang]

Hi,

I've scanned some maps but as my scanner is not big enough I had to scan 
each quarter on its own. I've imported these scans into a xy-location. 
Can I use i.group to group these 4 scans together and then i.points to 
get directly the full map? Or do I have to project the scans 
individually and to combine them after rectification?

Thanks for any help!
Wolfgang
