As I'he written before, I don't know the internals of osmosis. But if I the ways are clipped at a border, then it should be possible to create a new node at the intersection and mark the node as a border node. Is there a developper of osmosis reading this list?
I guess Brett has different priorities and a list of more important work. And it is not that simple. you need code to calculate intersection between ways and polygons. I bet osmosis doesn't have such code. this is not even a trivial, simple and fast thing to do. also you will need to use the same polygon across all tools to get the same border clipping. you need a slightly blown polygon since garmin tiles have a small overlap between tiles.
As some other users have written, then it would be possible to download the regions of interest from geofabrik and compile them with splitter and mkgmap and have a routable map.
no Geofabrik osm files are created with clipIncompleteEntities. impossible to merge them into a consistent format. They offer data for free. take it or leave it ....
Then its not neccessary to download whole europe, when I want only bavaria and austria. I could furthermore load the precompiled maps of countires onto my etrex, just as I need them.
but why split along the border? if you for example load bavaria-nord, bavaria-south+austria-northwest, austria-southwest-italy-nord is there any disadvantage? all borders are open in most of europe.why reintroduce them everywhere.
So I would really appreciate it, if the presplitted maps from geofabrik are clipped 'correctly' at the borders.
