There are also long sections of the Grantham Canal which are Nature Reserves:
there's a fantastic stretch in the Vale of Belvoir with masses of interesting
aquatic vegetation and in late May, early June a remarkable range of
dragonflies and damselflies. There are some conflicts in tagging
I note on the Natural England condition statement that they use the phrase
Residual Waterway, so perhaps we can make use of something like
canal=residual.
Jonathan Briggs did a nice article on the ecology of the Montgomery Canal in
British Wildlife a few years ago (BW, 17:401-410, 2006
Written last night, so some of this goes over ground already covered.
At one stage someone was doing a canal waterway map, but I think those
involved have other time commitments, like maintaining OSM editors and doing
the
default cartography.

An interesting set of points. I've been puzzling over three particular cases
related to this. In each case I'm aware that the tagging is incomplete:

AFAIK ward boundaries have been done in two places:

Broxtowe by will in the last few weeks importing OS Boundary Line data. In
the latter case data were imported and merged with

I'd echo Wilf's comments. There is a huge amount of detail which can be added
without worrying over much about the precision of the alignment. It's possible
to identify pedestrian crossings, traffic lit junctions, one-way signs on roads

GRASS seems to have some kind of Voronoi algorithm, but I find its interface
very non-intuitive, so have not found it to try it out. This may be worth
pursuing as an alternative route.
As an aside: I notice that virtually all postcode boundaries are obviously
created in this way. For instance

I've been experimenting with the
Civil Parish boundaries with QGIS and ogr2osm.py (modified to keep ways
below 500 nodes). QGIS seems rather temperamental about reprojecting
shape files: there are a huge number of settings which seem to affect
the base projection.
