Hi,

Don't worry about the dragged nodes, a lot of people do that while they're getting used to the web-based iD editor. It's usually easy to spot and fix.

Adding the roads from the developer's map is a problem, because it's subject to copyright. There's more information on the OSM wiki at https://wiki.openstreetmap.org/wiki/Don%27t_copy_from_other_maps

There is some aerial imagery available which is more recent than the editor's default "Bing Aerial Imagery". If you click on the map layers selector on the right side of the iD editor's screen, you can change the background to "ESRI World Imagery". This gives you some building/foundation outlines and roads under construction (some of which may be temporary). I've added some of these.

Until the available aerial imagery catches up, there are limited information sources which are covered by the Open Government License (OGLv3). I've added what little was available from the September 2025 releases of Land Registry INSPIRE Polygons and OS Open USRN and will take a look for any changes in the October release. There isn't anything in the April 2025 release of OS Open Roads, but this should also be updated later this month.

I realise that this sounds a little pessimistic, but there are a few things which you can do to get the new streets (and houses) onto the map quickly.

1) Walk the new streets with a GPS tracker like a sport/fitness watch or mobile app like OSMTracker or StreetComplete, then upload the GPX file(s) to OSM. If you click on the map layers selector on the right side of the iD editor's screen, you can select "OpenStreetMap GPS traces" as an overlay and then trace roads from them.

2) When streets have been added, you can use the StreetComplete mobile app (currently Android only) to survey and add details like pavements, surface, street lighting, etc.

3) If you want to collect some street level imagery which has a compatible license with OSM (we can't use Google Street View), you could consider using the Mapillary mobile phone app.

I hope that helps, but feel free to ask any more questions. Happy mapping!
