Re: [mkgmap-dev] Section of Country Boundary Missing
Hi all, Problem solved that section of the boundary is not included in 'zambia-latest.osm.pbf'. Obviously the bounding poly they use to create the file runs too close to the border and cuts this section off. I know there have been some border disputes in this region, some fairly recently. The problem is the demarcation of the border here in colonial times was not completed as the commission started it's work in the west where the border follows the watershed but the work was interrupted by the 2 world wars and the remaining borderline going east was based on old explorer journals and maps so certain landmarks used in these maps are disputed.

It occurs even if using the most basic of options in both splitter and mkgmap and using 'congo-democratic-republic-latest.osm.pbf' and 'zambia-latest.osm.pbf' from Geofabrik, the commands for both maps are as follows:- Splitter version 598 java -Xmx2000m -jar splitter.jar congo-democratic-republic-latest.osm.pbf > splitter.log Mkgmap version 4618 Java -Xmx2000m -jar mkgmap.jar --gmapi --remove-ovm-work-files=true -c template.args > debug.log I have had a look at the missing section on OSM using JOSM and can not see any reason there should be a problem, it is split here as it is also a part of the Kaputa district boundary in Zambia. I went back to a version of map created from data in November last year with mkgmap version 4587 and that had 2 breaks in the boundary, the section that now appears complete in the current maps has since been joined with the section to the west of it and that, it would appear, is the reason it is now complete. Any ideas? Cheers, Dave
Hi Dave, you should contact someone at geofabrik so that they change their poly file Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von dfjkman@gmail.com <dfjkman@gmail.com> Gesendet: Dienstag, 6.
