[OSM-talk] Converting polygon to OSM way?

[simon at mungewell.org]

I am playing with rendering paper maps, in the process I limit the data to
a particular area using osmosis with a --bounding-polygon using this type
of polygon:
http://wiki.openstreetmap.org/wiki/Osmosis/Polygon_Filter_File_Format

Is there a way to convert the same polygon in to an OSM way so that I can
merge this in and render it as a bounding shape (rather than the default
rectangle).

Cheers,
Simon.
