OSM Notes statistics

[angoca]

Have you thought about including some stats about notes? Something like:

• Notes opened by country.
• Closed noted by country.
• List of users creating notes.
• List of users resolving notes.

In fact, there are many stats that can be extracted from notes. These are some examples (In Spanish) https://wiki.openstreetmap.org/wiki/ES:LatAm/Proyectos/Resoluci%C3%B3n_de_notas/Preparaci%C3%B3n_premios#11._Ejecutar_queries_para_el_an%C3%A1lisis_sobre_las_notas.

That's indeed a good idea. Do you have any real-time stream source that we could leverage ?

• For instance, today I grab changeset info from Planet OSM : https://planet.osm.org/
  • I'm using a minute changeset replica, but unfortunately it seems that notes are only available daily

Any other idea are welcome :)

The only way to get real-time stream for notes is with the API. Notes are not as active as OSM changes, so you can poll it each 15 minutes.

Gotcha. The first version of my script was pooling the API, and some members told me to prevent doing this and use the replica instead. Since we don't have other solution available, and since that will be only every 15min, I believe we can go ahead with that way of getting fresh data.

At first glance, the issue I see is that I should use bbox with the API : https://wiki.openstreetmap.org/wiki/API_v0.6#Map_Notes_API And playing around, I got the error :

The maximum bbox size is 25, and your request was too large. Either request a smaller area, or use planet.osm

Not great, but that's a good start! Will continue later on

I think you should use: /api/0.6/notes/search

I am developing a tool to process notes that processes the planet notes file and the API. The scripts are at: https://github.com/OSMLatam/OSM-Notes-profile
