[mkgmap-dev] Split gmapsupp.img

Tue Oct 20 08:28:00 BST 2020

Hi Felix,

I also thought about this alternative. Sad news that it doesn't work :(
Yesterday I managed to download a map for Europe, so I think I have now the data to play with this.

Betreff: Re: [mkgmap-dev] Split gmapsupp.img

MapInstall cannot be scripted to create a gmapsupp.img (plus setting it up on linux is a pain). I'm pretty sure the <4GB gmapsupp part files - shouldn't be too difficult if mkgmap can associate the address index for the choses tiles only.
Right now for scripting I can only see how to create gmapsupp part files without address search.

Cutting Europe into smaller parts using osmcut or similar takes quite a lot of time, plus if you compile a full map of Europe anyhow already - would kinda double the work. And you would need to adapt the area rather often as osm data increases...
Having mkgmap split the map into parts would be great therefore (and also put out some sort of parts.list similar to the areas.list from splitter would be even better).

Hi Andrej

I know I can use MapSource/MapInstall to send parts of a map to device,
but many people have problems using this method, so I would like to have
way to provide ready to use gmapsupp files of my maps
