new splitter version r643
by Gerd Petermann 06 Nov '21

06 Nov '21

Hi all, see https://www.mkgmap.org.uk/websvn/revision.php?repname=splitter&rev=643 I've merged the branch now although the branch version sometimes produces slightly worse results compared to r642. As Felix pointed out one general problem with splitter is that the results for some countries or continents are not very stable. This also depends on the usage of polygons and the complexity of those polygons as well as the --precomp-sea option. I invested a lot of time this year to find better algorithms for the solver but without much success. So, I hope the changes don't cause any serious problems. If splitter fails to find a (good) split please report the used options and post a link to the file densities-out.txt. Gerd

Re: [mkgmap-dev] [mkgmap-svn] Commit r559: http -> https
by Ticker Berkin 05 Nov '21

05 Nov '21

Hi Gerd Just rebuilt this with Java 11 and after a warning about use of depreciated features, added <compilerarg value="-Xlint:all"/> <compilerarg value="-Xlint:-serial"/> <compilerarg value="-Xlint:-path"/> to build.xml (same as mkgmap and splitter). There were 3 problem file.

Failure splitting USA
by Carlos Dávila 04 Nov '21

04 Nov '21

Since a couple of weeks or so I'm unable to split USA. I have tried with my own extract and also with the one from Geofabrik <https://download.geofabrik.de/north-america/us-latest.osm.pbf>. Splitter crashes trying to find a nice split. I have tried different --max-nodes values, from 400000 to 1800000, with no success. Version used is 642.

MDR and city streets on different tile from POI place=city
by Ticker Berkin 04 Nov '21

04 Nov '21

Hi Gerd I've been checking the street list in the Mdr20 index to make sure they are attached to the correct city (as part of checking case-significance for the unicode/mdr errors) and finding discrepancies. I think this is because combiners/MdrBuilder, on a tile by tile basis takes the POI city list as the basis for Mdr5Records for attaching to streets and passing on for MDR processing. If the POI is in an adjacent tile to a road with the same mkgmap:city, there seem to be problems. This might be the reason for not being able to find some streets by city, rather than problems with case. I'm still trying to work it all out. Ticker

java.lang.AssertionError while building index from unicode tiles
by Carlos Dávila 22 Oct '21

22 Oct '21

Hi all I'm getting error below while building index from this tile: https://files.mkgmap.org.uk/download/523/31177029.o5m. Minimum mkgmap options triggering the error are: java -jar mkgmap-trunk.jar --bounds=bounds.zip --index --unicode 31177029.o5m Another tile from the same splitter run also fails but all other 65 of 67 build fine. With --code-page=936 they all build fine.
