Regarding Notepad++ : Maybe sed is a better tool for this, it is also awailable for windows. I don't know any OSM specific tool to "re-number" the ids. It would also be possible to add a conversion routine to mkgmap or splitter as long as you just want to subtract a constant from each id.

I probably won't want to do this often! And after the first two, I wrote a special purpose filter (in C#) which did it much faster than Notepad++ even allowing for the programming time!

Thanks again
