Hello everyone, I'm trying to do some reverse geocoding using Nominatim. So far it's great. However, there is a problem.

I'll give an example:

I've put some coordinates of a city that is yet to be mapped. Here are some coordinates:

lat: -24.18019,lon: -46.78167 - Returns a road called "Av. Condessa de Vimieiros", even though those coordinates belong to "Av. Rui Barbosa".

lat: -24.18083, lon: -46.78525 - Returns a road called "Av. Condessa de Vimieiros", even though those coordiantes belong to "R. João Mariano Ferreira".

Now, I think that this one road is being returned because it's the nearest thing mapped to the coordinates I provided. But is there some parameter Nominatim returns to identify wheter or not the location is precise? Or is there even a way to do this?

Thanks.

Just to be clear about the problem: there is a street at the selected coordinates, but it doesn't have a name (and therefore no nominatim place_id ?), so nominatime returns the closest named object without a mention of the nameless one.

@Vincent de Phily

Exactly this. There is a street in the said coordinate, but it doesn't have a name so it returns the closest one.

Is there a way to impeach Nominatim from returning me the closest place, and instead returning me an error message or something?

The nominatim api does not have this feature.

There is no workaround to this?

There are always workarounds:

  • You could use a different (reverse) geocoder.
  • You could write some new code for Nominatim, so it will support this in the future.
  • etc.

Yes, I understand this is not the answer you wanted to get, but sometimes life is just that way.

I get it. Thanks.
