[OSM-talk] Anomaly in OSM node IDs?

[Michał Brzozowski]

Hi everyone,

Recently I noticed that all AED defibrillators added using
https://aed.openstreetmap.org.pl/ get an ID that has two last digits equal
to at least 17. (also the higher, the less common).

See e.g.:
https://www.openstreetmap.org/changeset/123133265
https://www.openstreetmap.org/changeset/122369116
https://www.openstreetmap.org/changeset/121768114
and others.

I compiled stats in Poland based on ID suffix and they look like this:

(NB: Many of the AEDs were added in JOSM and don't have this numbering
pattern.)

Now, I think there is no way for the client to specify a created node
number before upload. What can be the mechanism causing this? FWIW, this
client holds an open changeset for 1 hour. Not sure what that would change,
though.

Client code: https://github.com/openstreetmap-polska/aed-mapa
