how to combine two raster maps

[E.A. Koster]

Can anyone tell me what to do ?

I have two rastermaps, e.g. A and B
both maps have different regions and a different scale
now I want to `overlay' these maps, but because of the different region and scale this won't work.

Acording to former answers I ran `i.points' and I have marked reference-points on both maps, but what do I have to do to bring these maps to the same scale and region so they will fit ?

g.help points me to the tutorial `Image processing', but where is this tutorial?

Maybe some one can tell me step-by-step how to do such a thing, cause once you have seen it ...

I hope someone can answer these questions,
Elwin
