Hi, in my application, I get the latitude and longitude of my position. My position is always a road/street because I am in a car. When I have the latitude und longitude, I make a request to Nominatim, e.g.: http://nominatim.openstreetmap.org/reverse?format=json&lat=LATITUDE&lon=LONGITUDE If at my position is only a road, then the request works how I want the request to work: I get the street I am on. But if there is a building in the near of my position, I get the building instead of the street. I can't use the street of the building because it is important for me to get the right section of the road because I need the way id for a further request (e.g. speed limit on the street) Is it possible to get just streets from Nominatim? asked 08 Jun '17, 07:04  FM_Pete |

That does not solve my problem. I am not interested in e.g. buildings, I just need streets.
Have you tried the parameter? Do you have an example where a building gets returned?
I tried it with zoom=18, I get the building then. With zoom=16 and zoom=17 I get the street I need. But why? The only thing I found about the zoom parameter is following:
zoom=[0-18]
Level of detail required where 0 is country and 18 is house/building
Where can I see the difference between e.g. 16 and 18 or 16 and 17?
You can test the zoom parameter on http://nominatim.openstreetmap.org/reverse.php?format=html&lat=35.144792512496686&lon=-90.00751018524171&zoom=16 The red circle is the search point (where you clicked on the map), the blue circle the result that got returned. A zoom=3 will return only the country, zoom=16 the street, zoom=18 the building (address, housenumber, POI) if found.
Thanks for your help!
