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

None that I know of, but Osmosis will at least truncate ways at the
first node outside of the specified box/polygon (or at the last node
inside...? not sure ATM). I know that one of the Osmosis guys,
probably Karl Newman, wanted to implement something like proper
truncation with phantom nodes or so in order to prepare data for
Garmin imports.

You know that if you specify a proper <bounds> element in the
Osmarender rules file, Osmarender will create SVG clipping for the
specified area?
