>
> Hi,
>
> I am unsure this is the best place to post this, but have a question
> regarding creating maps with osm maps updated with osmupdate. I
> usually start from an .osm.pbf map downloaded from Geofabrik, and in
> order to avoid downloading it again, I use osmupdate to maintain it
> (or a converted .o5m version of it) up to date. I noticed that my maps
> were becoming bigger and bigger, days after days, but *bigger than a
> plain redownload* of the map on Geofabrik.
> 1. Is this normal? Does osmupdate just append the changelog to the
> original file?
> 2. mkgmap-produced maps become significantly bigger too: is it normal too?
> 3. If the changelog is just appended to the map, is there a way to
> rebuild it from scratch to get the same map than on Geofabrik?
>
> Thanks for your help.
