Hi! Welcome to OpenStreetMap. I'm the mapper who has added many buildings and addresses in this area. FYI, the Bing images are slightly in the wrong place in our area. You need to use an offset of (3.93,-2.23) - https://blog.mapbox.com/better-openstreetmap-data-with-ids-new-imagery-offset-tool-ff1906ef6c53 . Unfortunately, with the online iD editor you have to enter the offset every time you make any offsets (if you use JOSM editor it can be automated). Hope that helps, thanks, Stephen

Hi! Welcome to OpenStreetMap. I'm the mapper who has added many buildings and addresses in this area. As you have no doubt found, adding a rectangular building is tricky in the online iD editor. One thing you might want to consider is using the JOSM editor - https://josm.openstreetmap.de/ - which provides tools for making buildings rectangular (although it takes a little time to learn how to use it). In addition, the Bing images which you are copying from are slightly in the wrong place in our area. You need to use an offset of (3.93,-2.23) - https://blog.mapbox.com/better-openstreetmap-data-with-ids-new-imagery-offset-tool-ff1906ef6c53 Hope that helps, Stephen

Hi! Thanks for contributing. When using the iD editor you have to add an offset to Bing maps of (3.95,-2.22) in this area. This is to adjust Bing to meet the "correct" alignment of the Cadastral data - https://osmuk.org/cadastral-parcels/ Let me know if anything is unclear

Hi! Thanks for adding the houses. I recently aligned the roads in this area to the new Cadastral imagery data. The Cadastral data is considered to be the "correct" alignment in GB - https://lists.openstreetmap.org/pipermail/talk-gb/2021-March/026352.html You can access the cadastral data in iD as a layer, and you can align the Bing images using (3.36,-2.54).

Hi! I see you added tunnel=yes to these footpaths through buildings. Should it be tunnel=building_passage? tunnel=building_passage Thanks

Hi! You changed this and another from bus_stand to bus_stop. But they are not bus stops - buses never pickup or dropoff here. They are in fact bus stands, where buses wait.

Hi, the iD editor is indeed the one most new users start with, but it does have some real practical limits. For example, its hard to get square building shapes. If you use it, you can see the cadastral data here: https://twitter.com/osmuk/status/1368983036751187972 and you can enter the offset of (3.95,-2.22) in the settings every time you edit.

Personally I use JOSM - https://josm.openstreetmap.de/ . It can be a bit of a pain to get installed, but it is much more powerful, especially once you learn the key presses (such as q to make a building square) and install the plugins. I use imagery_offset_db plugin to manage the offset (which is remembered for each editing session). I also use building_tools plugin to rapidly create buildings and HouseNumberTaggingTool plugin to speed up address entry.

It is also possible to use JOSM to solve the need to realign buildings to the imagery. By using the find feature you can select all buildings on a street and then drag the whole lot to the new position!

Thanks for your work so far, I hope this is a good start for whether you might move to JOSM, or even just use cadastral and offset in iD.
thanks

The official-ness isn't perfectly explained, but this is the best link I have http://gis.19327.n8.nabble.com/OSMUK-response-to-Accuracy-of-cadastral-parcel-alignment-td5986988.html and there is this tweet about iD editor https://twitter.com/osmuk/status/1368983036751187972 . My offset is setup in osm.wiki/Imagery_Offset_Database under "Cadastral at Wiimbledon Chase". (Cadastral data is not 100% perfect, but I checked a few locations around Wimbledon Chase to ensure my choice was OK, and I always switch the layer on for each edit session.)

Hi, I noticed you have been aligning roads to Bing imagery. Are you aware that Bing imagery is frequently incorrectly located? Did you know that OSM now has Cadastral boundary data that is being used as the golden definition of alignment in he UK? I've setup a new offset at Wimbledon Chase of (3.95,-2.22) for our area, and just wanted to make sure you knew about it. Sadly, according to this "official" definition, the alignment of Green Lane is correct at present but your changes to Longfellow Road are not. If you use JOSM editor there are plugins that can handle this, but sadly the ID web browser editor requires you to type in the offset of (3.95,-2.22) every time you open the editor. If anything is unclear I can help you get setup correctly.

This changeset needs to be reverted. The roads in Merton are 20 mph. (I live here and know this for a fact)

Hi! Loving the work you are doing in the Stoneleigh area. Rather than using a note, I'm now using "indicative=yes" for fences like this (even though it is not documented, it makes perfect sense as a tag)

What data are you using to make this change (and your other changes over the country)? Merton borough is a 20 mph borough, and that includes Grand Drive - I have local knowledge...

96067819 about 5 years ago

The speed limit on all of these roads is 20 mph

FWIW, I disagree with splitting residential areas to the degree you have done here (Bordesley Road). My strategy is simple and generally mechanical - tertiary roads and above should not be within landuse of residential, but residential roads should be. This rule is easy to explain and makes logical sense (a residential road is as much a part of residential landuse as the housing). PS. a lot of this changeset is OK with me.

Its good to see that the two offsets (3.43,-1.03) and (4.1,-1.7) are not that different :-)

93982818 about 5 years ago

Hi, FYI the Bing mapping you have moved everything to is not necessarily accurate below 5m. Across the Wimbledon - Surbiton area I'm using an offset of (3.43,-1.03) which seems to better align with boundaries and what has been added to the map before. As I say, no need for any specific action beyond awareness that mass moving to imagery isn't necessarily the right thing to do.

Hi! Just to let you know that I've been using an image offset for the new Bing imagery in the Wimbledon / Raynes Park area, because Bing seems to be inaccurately positioned. The offset is (3.43, -1.03). Sadly, this has to be manually entered into the ID editor in every editing session. Thanks
