Yes, it relatively easy... I'm just lazy and wondered if it had been done
already (with some code which really did it right - ie. copying with holes
etc.).
My simple hack method was:
head -n -2 alberta2pts.txt | awk -f poly2way.awk test.osm
poly2way.awk
--
BEGIN {
offset=200
print ?xml version='1.0' encoding='UTF-8'?
print osm version='0.5' generator='poly2way'
}
{
if (NR 3 ) {
printnode id='- NR+offset ' visible='true' lat=' $2+0
' lon=' $1+0 '
print/node
}
}
END {
printway id='- NR + 1 ' visible='true'
for (count=4; count NR; count++) {
print nd ref='- count+offset '/
}
print nd ref='- 4+offset '/
print tag k='boundary' v='boundary'/
print/way
print /osm
}

I'll place a reference on the Osmosis page for others trying to do the same Simon. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Can also do poly2osm, which is nice for the cases where you want to refine an existing poly file.

It's very straightforward. Just needs a program to take the one file format and turn it into a different file format. Just create a bunch of new nodes, connect them together with a way, then add the appropriate metadata for your renderer. Number the nodes and ways with negative numbers. Or come to my talk at SOTM (if you're here) on Sunday morning.
