New hyper-detailed garden fence mapping in London

I think part of the problem is a tagging/rendering issue with private household gardens being shown too prominently, in the same way as a public garden (which should be prominent, unlike private gardens).

Fences/walls and also road areas are used on large scale Ordnance Survey maps and I think are worth mapping in OSM to achieve something that is as at least as good. See this area on an old OS map for an example https://maps.nls.uk/geo/explore/#zoom=17.11941827233819&lat=51.56964&lon=-0.11352&layers=173&b=1.

That’s not to say though that it’s not worth trying to ensure the level of detail is balanced across an area, but you have to start somewhere when you want to map in detail. Ideally I think it’s best to start with town/city centres where the main amenities etc are, but if someone wants to add lots of detail to their local area I don’t think this should be discouraged.

OS OpenData Street View in JOSM

WMS method:
I've also had problems a number of times with using WMS layers in JOSM. Have you tried using other WMS layers and seeing whether you have the same problem with those, or are you just having problems with the OS StreetView WMS?

Sometimes I've found after waiting a while I still have a black screen, or I have 'Exception occurred' red tiles. When this happens I delete the WMS from the layers panel (at the top right) in JOSM, and reload it - it often seems to work the second time. I usually adjust my position on the map and zoom level before reloading it - but I'm not sure that is necessary.

SlippyMap method:
I've not really found any problems with this except when zoomed in more than a certain level, which has resulted in a blank (grey) screen. To fix this go into the SlippyMap plugin settings (one of the tabs in JOSM preferences) and ensure that 'Max zoom lvl' is set to 17. Also make sure that you have OS StreetView selected in 'Tile Sources', that 'autozoom' and 'autoload tiles' are ticked.
