[mkgmap-dev] Split gmapsupp.img

Sun Oct 18 08:50:03 BST 2020

Hi Carlos,

see http://gis.19327.n8.nabble.com/Split-gmapsupp-img-files-over-4GB-tc5967656.html

I tried to code this at that time but got stuck because I didn't have the time to create such a large map to find out where MapInstall places the other files (e.g. MDR, TYP and if any other file or flag is needed.
Maybe I'll give it another try with a download of Europe made in 2019. Splitter will stress my PC for quite a while ...

Gerd

Betreff: [mkgmap-dev] Split gmapsupp.img

As far a I know, mkgmap is able to produce unlimited size gmapsupp
files, but SD cards and internal device memories have a limit of 4 GB in
a single file. To overcome that limit, recent versions of Garmin City
Navigator maps are split into several gmapsupp that work as a single one
in devices which include them. Would it be possible to add an option to
mkgmap, so that it automatically splits gmapsupp when you process a map
that is larger than 4 GB?
