That's the problem, I cannot even create an overview map. All I see are tmp files. If I discard the UK & Ireland (68 tiles only, 800MB) I can create the total map of Europe. The mdr size is 373 MB and img size 12 MB. I fear I'm hitting the limit of the index siz, I've also discarded the x-split-name-index option but it didnt help. BTW @Thorsten, I was counting ovm files too, so the total number of img is 1145 tiles im using splitter 321 does it make sense to split all tiles again with 421? ----- Oorspronkelijk bericht ----- Van: "Gerd Petermann" <gpetermann_muenchen@hotmail.com> Aan: mkgmap-dev@lists.mkgmap.org.uk Verzonden: Donderdag 14 mei 2015 10:03:28 Onderwerp: Re: [mkgmap-dev] EU map too big? Hi Minko, hmm, there is no need to create the ovm_* files again. Maybe the problem is not the overview map? Please double check that you use r3595. The limit that is reached is 16MB. Is the compiled overview map ~ that size? Gerd
