Hi Gert, normally splitter uses Garmin units, the log shows e.g. Map is being split for resolution 13: - area boundaries are aligned to 0x800 map units (0.0439453125 degrees) - areas are multiples of 0x800 map units wide and high So, if you force a split at other boundaries this might cause problems, at least with routing. I suggest to post a link to the special tile for detailed analysis. ciao, Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von thesurveyor@wolke7.net <thesurveyor@wolke7.net> Gesendet: Samstag, 5.

Hi Gert, the error message seems to say that the problem occurs while reading elevation data. Maybe mkgmap should not set the "show-profiles" flag when no elevation data was written. I'll see if I can reproduce the problem tomorrow.

Sometimes even this is not necessary and Basecamp crashes without interaction directly after it has loaded the map - maybe 5sec later. I have attached the osm-File and a track (kml-file) around it.

Die Grenzen im split-file (areas.list) sollten in *G*armin*U*nits geschrieben werden. 1GU =~0,0000214576... (exact : 360°/2^ 24). Und die GU sollen ohne Rest durch 4 teilbar sein. Beispiel: 47 ° /0,0000214576=2.190.366,117 *GU* .Die nächste durch 4 teilbare Zahl ist : 2190368. Mit diesem Verfahren gab es noch nie Probleme. Routing funktioniert. Die Abweichung zu 47° ist 0,00004039...° (weil 2190368*0,0000214576 = 47,0000403968°). Weniger als 5m .Kannst praktisch vergessen. thomas Am 05.08.2017 um 20:54 schrieb thesurveyor@wolke7.net:
