Re: [Gimp-user] Huge image problem

The obvious question for me is: what do you hope to do with the finished 
map? Mount it on a wall? Make it the size of a driving map? Put it in a 
book? Put it on the web?

Your end use will determine how you reduce it. Don't forget that optical 
processes (high resolution map making camera or scanner) may be your friend 
for at least reducing the huge physical size to a working size. Film has far 
greater resolution than digital.

File sizes are affected by bit depth, number of colours and resolution.
