H Andrew,

you better use a memory stick for transfer. These files get big. Anyway, on 
Linux GDAL can read all popular formats like tiff, png and jpeg. 

Some tips for scanning and processing:

* 600 dpi is enough. 
* If you scan the map in multiple parts do a generous overlap. Scanners tend to 
have a lousy quality on the edges.
* If you have the opportunity use a scanner that scans the map as a whole. It 
might cost a bit of money but it saves you loads of trouble
* Try to flatten the colour space of the scanned map and convert it to a 8bit 
colour table. But pay attention: The same colour table has to be applied to all 
scanned fragments of your map.

Once you are done with your scanning, you have to reference the map. QLGT can 
help you with that (F1->F6). If your maps have a known grid printed on you can 
use it with the grid tool. If not you have to take a couple of well known 
points like crossings.
