[mkgmap-dev] Small holes in boundary coverage

From WanMil wmgcnfg at web.de on Sat Apr 7 13:28:51 BST 2012

Hi Gerd,

can you please post again the identical output patch? I cannot find it 
on my computer and the patch referenced by nabble cannot be found

> java -Xmx1600m -Xms1600m -jar mkgmap.jar --remove-short-arcs --route
> --preserve-element-order 63240022.osm.pbf
> If I comment the call of UnusedElementsRemoverHook I get a different output
> file.
> I hope you can reproduce it?
