Re: [mkgmap-dev] error splitting binary files
I tried to split an extracted area with osmosis too. Same errors. I suppose you need to set osmosis to --write-pbf in order to get a binary abstract? aighes wrote: Hi I know, it wont help you, but I haven't nay problems with pbf-input and modified area.list.

Re: [mkgmap-dev] error splitting binary files
Hi, I tried it again, splitted then europe.pbf now without osmosis and without errors. So i don't know what went wrong the first time.

WanMil Mmmh, within the next days we have to think about tuning the rules. At the moment the blocker will block too much. I also think, the best approach is to first look at the size of the sea. Then divide the size of the sea against a rating based on a score of attribute to each highway that falls into the sea based on a rating. (e.g. 0 for any highway or railway with brigde=* or tunnel=*, residential0=.5 , primary/secondary=0.3, highway=* (sac_scale=* | mtb:scale=*) ==1,...) ===score X. Once this division reaches a certain factor, assume the sea is wrong. and drop it. Additionally or alternatively look at how much area (percentage) of say forest falls into the sea. If too much forest inside the sea, then bang, drop the sea. I'm not sure what is quicker to calculate. Areas like forest or certain highways (number). ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] mkgmap and threads
Hi Is there any chance to remove this synchronization to get a gain of more threads? What has to be done to remove the synchronization in the MapMaker class? I am pretty sure that the synchronization is not needed now and probably never was. In any case, even if some synchronization is needed, it shouldn't be around the complete reading routine. I'll remove it. ..Steve ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev

Re: [mkgmap-dev] Flood blocker
There will always be a problem that the flood blocker removes too much of the sea area. Regarding you example: I think the road must be tagged with bridge=yes. Have a look on the wikipedia photos and decide yourself: http://en.wikipedia.org/wiki/File:Deltawerke-Oosterschelde-Sturmflutwehr_Oosterscheldeseite.jpg http://en.wikipedia.org/wiki/File:Pont_de_Zeelande.JPG But in general the flood blocking logic must be more gentle to some mapping oddities. I think Felix has made a good proposal. Any other ideas?

Re: [mkgmap-dev] Splitter question
I've taken some time and played with the suggestions given. I'm including two scripts. One (doit.nl) is a sample script to split the OSM file for the Netherlands into manageable pieces, and then to convert the OSM files into RoadMap format. This mostly works : - I get 339 map files - 9 maps turn out to be too big still for RoadMap So I created another script (deeper.nl, used in a subdirectory, you'll notice that in the script) that'll take the files I put in the subdirectory, and divide them in four smaller chunks. I used deeper.nl and still had problems with 3 of the smaller chunks so I reran deeper.nl one more time, producing maps that were (again) four times smaller than the offending OSM files. This worked. So the 8GB netherlands.osm file got converted into some 380 RoadMap map files, totalling about 1.6GB. I realize that I'm working around something splitter is leaving unsolved, and I'm partially automating this, my question is whether all this is a good idea.
