Yesterday I tested pbf input for mkgmap for the first time. Map was built apparently without errors, but using the resulting map on MapSource I get a suboptimal route, compared with the one I get using osm as input. I used portugal.osm and portugal.osm.pbf from geofabrik for the test. Today geofabrik is offering corrupt excerpts, so I can't make further tests by now.
That is interesting. If the .osm and .osm.pbf contain the same data then mkgmap should produce exactly the same map in both cases ignoring timestamps if you add --preserve-element-order in both cases. In the cases I tested this was true. If it doesn't then it is a bug. Now the fact that if you don't have --preserve-element-order there could be differences in the order of the elements within the maps and I suppose that it could affect the routing. If so that would be very interesting and might lead to improvements in routing in general. ..Steve
