OpenStreetMap community

That's a good usecase, but finding something based on incomplete or wrong data is harder than just surveying what's on the ground.

If you look for something and you find it, it's good and easy, you just copy it to osm. But what if you can't find it? If it's not on the ground you can't be sure why and what to do next:

• The location of the element on overture was just simply wrong. So you shouldn't delete it, but move to the correct location. So now you have to look for it on a wider area to find the actual location.
• The element does not exist anymore, so you it shouldn't be on the map at all.
• The element actually never existed, it was just a joke of a teenager, there were never any QA run on these nodes, so you just lost a lot of time from your life searching for something never existed.
• And what if you just missed it accidentally or something similar.

The problem is you cannot really edit the source of overture. You cannot ask fb to delete someone else's page because it's out of business, or update its address. You cannot tag it as invalid, because currently we have only read only access to overture, you cannot contribute data there.

But overture is relatively new, and I hope the tools will get better, and maybe it will be a bit more usable for the wider community in the future.

I did similar things on osm, tried to find unnamed hostels made by anonymous maps.me users, it's awfully hard to find something when your only info is it's a hostel, and it should be somewhere in this neighborhood. Because you can only delete the wrong hostel if you checked all the surrounding buildings if there isn't an untagged hostel hidden somewhere.

And if you can ask people who live near, why not ask them to simply add the POI? We don't need overture for that, and it's about the same amount of work, and it's much more fun. There are genial and easy to use tools for adding new places to osm aimed at casual mappers: StreetComplete, Every Door, OnOsm.org just to name a few.
