[Talk-us] Survey Township Sections

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

Re: [Talk-GB] Waterways Map (was invisible)

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

Apologies, again, for top-posting. 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 ( in car parks) etc.,

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

Re: [Talk-GB] OS Boundaries

Apologies for top posting. 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.
