For me it sounds strange to handle such big files.

Is the map you download from Google really that big?
Mostly Google maps uses normally tiles of sizes 256x256 pixel, wich you
have to compose to get the  big image.

If your problem is to combine tiles with different palettes, then you
should pobably look at a way to  'unify' the palette of all tiles befor
combining them.

Being no expert of PIL I don't know whether this is easily possible though?
