How to find out which POIs have not been edited for a certain timeframe?

Help and support

Hello everyone,
for the last few days I’ve been trying to come up with a way to get a geojson file that includes the POIs that have not been edited for more than 2 years.
I need this to create a maproulette challenge.

So far I’ve played around with the overpass API but seemingly cant find a way to output this kind of information - maybe I am missing something?
I have also tried:

  • to use an internal geofabrik export and load it into QGIS but my limited RAM doesnt help and I have never managed to load the .osm / .osm.pbf file even with an increased swap.
  • I have tried my luck with ChatGPT generated Overpass + python code but the result is as good as one wold expect (useless)

Last Idea was to use overpass to get a current data export of the POIs from now and one from 2 years ago and then use some computer magic to compare and filter for things that havent changed. However, I dont know if this is feasible and its definitely beyond my capabilities.

I feel like I might just be overlooking a simpler solution but can’t seem to find it.
So I hope someone in this community has already found a solution to this problem and is willing to share it

Thanks!

To what purpose? Maproulette is for finding problems with existing mapping.

Not being edited for two years is certainly not a problem and such a challenge could encourage edits for no reason.

Most POIs don’t change that often.

You can do that with Overpass like that:

<your_query>->.a;
nwr.a(newer:"2021-10-20T00:00:00Z")->.n;
(.a; - .n;);
