[OSM-talk] Local map making - truncating ways on boundary?

[Brett Henderson]

I hope the job loss isn't too much of a downer, best of luck finding 
something better.

As for tiling, I hadn't considered polygons.  They sound nasty.  I'd 
been thinking of something far simpler.  For ways I was thinking of 
splitting them at tile boundaries, adding synthetic nodes as required, 
and creating new way ids where one way becomes multiple ways.  Polygons 
change all that.  Initial thoughts are just detect closed ways and split 
accordingly to make closed polygons inside each tile.  It sounds like 
that may not be appropriate though.  Splitting polygon types according 
to tags and rules adds a huge level of complexity and will constantly 
require updates as new tags and polygon types are defined.  I also get 
the impression from your wiki page that this will be very Garmin 
specific, and perhaps that's the only way to go.

I'm going to have to back away slowly from this one and pretend I didn't 
see anything ;-)
