Re: [Talk-GB] UK coastline data
> Just a quick comment. Parts of the Maxar imagery seem to have significant offsets. I have noticed that too. The geometry is often wonky with incorrect angles. I'm not sure how that's possible, but comparison with something like Esri reveals it. At the moment I'm using it more for confirming details that aren't present on older imagery rather than trying to get precise geometry from it.

Re: [Talk-GB] Removing "WikiProject" prefix
Hi, Russ. Thank you for commenting. I don't know the pages naming conventions for other types of pages, as I told Andrew in a previous message. In place pages (United Kingdom, Spain, London, Madrid, etc.) it is not recommended to use the prefix "WikiProject". I collaborate on a wikiproject aimed at improving the translation of the wiki. In that case, I think it makes sense to use the prefix "WikiProject". In the case of the "WikiProject Power networks", I don't know. I will rename only the pages "WikiProject United Kingdom" then. I won't rename the "WikiProject Power networks" pages. If the contributors of the "WikiProject Power networks" want to rename it, they can do it later if they wish. Thanks again for commenting.

I think I'd be happier renaming the whole "WikiProject Power Networks" namespace to "Power Networks" and keeping the structure within that. I can check if this is acceptable with the infrastructure mappers I know (I suspect it will be).

Re: [Talk-GB] UK coastline data
Hello again, I've finished integrating the VectorMap data all the way along North Norfolk and now the Blackwater estuary too. I did a survey in Maldon before I made changes near the town to make sure nothing was wildly different. It looks like the new Maxar imagery is quite recent in that area and, helpfully, was taken at low tide. I made minor adjustments to the VectorMap data in places where the more recent imagery showed significant differences. I wanted to fix up some other coastal areas I'm familiar with, such as around Folkestone and Dover, but these areas consist of features other than beaches and mud flats that are less clear to me how to map (like "beaches" consisting of large rocks from the cliffs). There has been a change merged into osm-carto which will, in my opinion, degrade the rendering of many of these tidal areas. You can see the change here, along with my concerns at the bottom (I am georgek): https://github.com/gravitystorm/openstreetmap-carto/issues/3707 Doing this work, and seeing the above changes to osm-carto got me thinking that the time is ripe to sort out how we do water in OSM. There are fundamentally two concerns which are currently conflated in OSM: * The water area, ie. "you will not be dry if you try to stand here", * The water boundary, which could be a river/sea bank, a building, a mean high water level, and maybe other things. The area and the boundary are both important for different reasons and convey very different information. At the moment we handle boundaries very poorly in OSM. This makes actually rendering the boundary very difficult, because it will actually cross water areas in at least two cases: where rivers meet oceans, and where river areas join together. If these were all done using multipolygons we could separate the concerns completely. So I propose to do this: map areas as multipolygons and boundaries by ways which define multipolygons. Water boundaries could be any of: * natural=coastline, this should roughly correspond to the legal boundaries of the country, ie. the coastline is the edge of the country, * natural=riverbank, for rivers, usually these are managed separately from sea banks, (we can't use the unfortunately named waterway=riverbank, because that actually defines a water area, not a river bank), * natural=shore, for lakes and anything else? * anonymous ways, for cases where the bank is not very significant, this can just be mapped as a normal polygon, for example a pond, These boundaries can coincide with orthogonal tidal features which I also propose: * tidal:mean_high_water_spring=yes, * tidal:mean_low_water_spring=yes, * tidal:... for other levels of interest like astronomical low (for nautical charts), Note that these can exist where no bank is present, e.g. on beaches. These boundaries can also contain many other useful pieces of information such as: material of bank, man made or natural, mooring, ownership, management and probably many more things. It could be quite possible to have a way in which all of the following features coincide: * natural=coastline, * tidal:mean_high_water_spring=yes, * tidal:mean_low_water_spring=yes, * man_made=sea_bank, * material=concrete, * barrier=wall, * mooring=private, It's also quite possible to have a completely distinct seabank, high water level and low water level, e.g. in areas of reclaimed land where a man made sea bank is a flood defence and is well above mean high water level. Sorry for such a long post. I would like to identify any problems with what I'm thinking quickly before I proceed to make proposals for these on the wiki. So if I could ask people to just give a rough thumbs up or thumbs down to this kind of approach I would be grateful. Thanks, and happy mapping, Borbus. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Re: [Talk-GB] Removing "WikiProject" prefix
Hi, I'd just rename these pages: WikiProject United Kingdom --> United Kingdom WikiProject United Kingdom/Parcel Lockers --> United Kingdom/Parcel Lockers WikiProject United Kingdom Sustrans Artwork --> United Kingdom/Sustrans Artwork And in response to Andrew's request: WikiProject Power networks/Great Britain (redirect) --> United Kingdom/Power networks WikiProject Power networks/United Kingdom (redirect) --> United Kingdom/Power networks I'll wait a couple of days in case anyone disagrees. It's really a minor change, it doesn't matter much. Just remove the prefix "WikiProject" from the pages related to the UK mapping project. That's all. I will take the opportunity to add the category [[Category:United Kingdom]] to pages which are not yet categorized and are related to United Kingdom. Thank you for your collaboration.
