Why not ask your question on the new OpenStreetMap Community Forum?



I'm using Nominatim to reverse geocode an OSM way. However there are some ways that cannot be geocoded. Please see: https://nominatim.openstreetmap.org/reverse?osm_id=126761805&osm_type=W

I'm revisioning this using overpass api (that's where I got the way id from) and it shows some info. https://overpass-turbo.eu/s/HAv

Why does Nominatim return Unable to geocode? Does it mean that Overpass and Nominatim API use different databases? Or is Nominatim cutting off some ways by default?

Nominatim only imports features with names or reference numbers. https://wiki.openstreetmap.org/wiki/Nominatim/Development_overview#Tags_processed Overpass might be better suited if you're looking for unnamed ways.

If you run your own instance of Nominatim you can change the defaults to import more (or less) https://github.com/openstreetmap/Nominatim/issues/1340

For lookup of features by OSM type and OSM id, the /lookup endpoint will be faster http://nominatim.org/release-docs/latest/api/Lookup/
