Can now explicitly tag boundary nodes with mkgmap:on-boundary=1.

Apologies for the beginners question, but how do I use this? In the OSM source like this?

<node id= "-1" lat="11.00" lon="103.72" > <tag k = "mkgmap:on-boundary=1" /> </node>

I am assuming this is to allow us to mark external nodes that connect to external nodes in other tiles - is this correct? This would be fun to experiment with, splitting tiles in gpsmapedit, converting them to osm format and then compiling.

It's me that should apologise for committing that addition with no explanation. It explicitly says that a given point is a boundary node. Of course, it only makes sense to do that for routable ways.

Boundary nodes are normally created automatically when a routable way is clipped at the tile's boundary. This lets you create a boundary node anywhere.

It's used like this:

<tag k='mkgmap:on-boundary' v='1' />

So, you were nearly right.

Mark

Thanks for the more detailed explanation. Garvan
