Hi, I don't know if this was already a topic or a known issue, I haven't found anything about this. There were some reports that citys of the Netherland like Amsterdam or Apeldoorn are not findable via city search, but by address search. I found out that this is always the case if there are two or more POIs with the same name in one city. Amsterdam has two POIs with the same name: the city (place=city) and a hotel (tourism=hotel). Apeldoorn had even three POIs. Needless to say, that you can find with the City Navigator Europe V8 (yes, already quite some years old) all POIs. Is this a known limitation or a bug?

I wasn't aware of that problem, I shall have a look at it. ..Steve

All POI names are de-duplicated so that there is only one per map and region. Not really sure what the point of that was as in almost all cases I would expect that two POI's are different even if they have the same name, unlike the situation with roads. Attached patch removes this behaviour and allows all POIs to be found. ..Steve

Could that be a try to solve the problem with duplicate POIs if you have one POI generated from a node and one from an area?

Thanks, I will try test that now. Thorsten -- Thorsten Kukuk, Project Manager/Release Manager SLES SUSE LINUX Products GmbH, Maxfeldstr. 5, D-90409 Nuernberg GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg)

That wasn't the motivation - it is just all the other sections are de-duplicated. But you are right, you may get duplicates in the index with the patch where you wouldn't before. ..Steve

Yes, and I tried to think already about how to solve this, but there is no trivial solution. The only way I see is, to check if a node is inside a polygone with the same name/attributes if --add-pois-to-areas is given. So at least all McDonald's in Nuernberg are now findable again ;) I will test the map over the weekend and look, which duplicates POIs there are now.

I tested the maps yesterday and today and it seems to work fine in BaseCamp, Mapsource and on my 62s. I can find all POIs missing before, even such ones I didn't missed. All now duplicate POIs I could find are bugs in the OSM data.
