I have researched boundaries
of the English counties and unitary authorities. it seems that
generally they follow the mean low water mark. Some of the land
is owned by the council, some by private owners but often by the Crown
Estates and leased to the council. By using the low water mark the
council administers the beach or foreshore and the Crown Estates
administer the seabed beyond. Cheers, Chris Bogus Zaba wrote: I have completed the following relations for Unitary Authority Boundaries and put them in the Wales Wiki : Wrexham (137981), Flintshire (198566) and Denbighshire (192442). Now some inevitable questions:1. How should Flintshire and Denbighshire be completed out at sea? On the Wales Wiki it says "The current Wales Boundary (08 July 2009) is both wrong and unhelpful." So I guess I should not be using that. Currently Unitary Authority boundary lines go out to sea traced from the NPE, but they do not join up with any coastal boundary. As it happens in this part of NE Wales, nobody seems to have made the coastline (high water mark?) ways to be members of the national boundary relation, although that has been done for about 70% of the welsh coastline. 2. In putting together the relations for these boundaries I found myself splitting a lot of roads and streams into relatively short sections so that I could then make these sections members of the boundary relation. Is this recognised good practice, or is it better to make a separate boundary way which simple shares nodes with the relevant stream or road etc ? 3. In doing all this I have used the NPE layer which can be used as a backdrop in josm and potlatch. I have realised that this NPE is not the same NPE as can be found in other places (eg the postcode collection application at http://www.npemap.org.uk/). The latter is clearer than the tiles in josm and potlatch especially regarding parish boundaries (which you find yourself tracing) which are nice dotted lines in the postcode application and faded grey lines in the josm/patlatch layers. Can the clearer (newer?) tiles be made available in the osm editing environments ?
