@pr06lefs @lemmydividebyzero you should really only use @fdroidorg if you buy in to their philosophy that everybody is out there is trying to get you.
Essentially if you have a web service and write an app for it, or you write/use a web service that supports the functionality of the app that can't be simply replaced (because it is app specific) they will immediately "anti-feature" you. Its a shame because it makes it difficult to find the real issues in all the noise they produce.
@Showroom7561 the two Esri imagery sources are the ones defined here https://github.com/osmlab/editor-layer-index/tree/gh-pages/sources/world
@Showroom7561 while it doesn't look good (multiple orgs claiming rights in the imagery), I would suggest contacting the e-mail here https://maps.durham.ca/arcgis/rest/services/Cached/_Basemaps/DurhamImage/_UTM/MapServer and asking if they would be prepared to allow OSM access for tracing, the details would have to be hashed out naturally.
@Showroom7561 if you have a link to your municipalities imagery in some form I can give it a quick look.
@Showroom7561 you seem to be jumping to conclusions a bit there. Yes we are allowed to use Esri World Imagery in its two variants, there is no permission for anything else.
PS: there have been cases were Imagery was available in the Esri imagery referenced above that wasn't legally available for use to us elsewhere, in the cases that I tracked it 'suddenly' vanished after a while.
@foxy @danish @openstreetmap you need to differentiate between reusing existing nodes for other purposes (as in your example), which irl works against preserving history, and using an existing element for a new or different facility in the same place (there is some grey area there obviously).
@danish @openstreetmap naturally I do have to add one nerdy and nitpicking observation. It is actually "nearly all elements in OSM", as versioning was introduced with API 0.6 https://wiki.openstreetmap.org/wiki/API_changes_between_v0.5_and_v0.6 in March 2009, elements deleted before that date are literally gone.
@danish @openstreetmap in general edit the existing one, all elements in OSM are versioned and it is considered best practice to maintain the history of objects.
@malte @qgis @qgisDE @openstreetmap IIRC @josmeditor https://josm.openstreetmap.de/ has support with a plugin, otherwise simply convert to GeoJSON and you can use JOSM and @vespucci_editor. Naturally you should check that you are permitted to use the DEM to contribute to OSM.
