I've constructed the following query, I want to get "hospitals" which is a special phrase according to this link https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases/EN This is my query those GPS coordinates are from Pittsburgh, PA. But the results contains results from Nicaragua and Libya and they are not hospitals. Where have I made a mistake? asked 29 Jul '18, 16:40  Dave4784 edited 29 Jul '18, 21:38  aseerel4c26 ♦ |

A special phrase just means that nominatim will give some preference to items tagged amenity=hospital, it's still doing name matching on "Hospitals", so it's returning things with exactly that name. Here's an example Overpass-API query that returns hospitals within a 10 Km radius of that location. Note that you can use that query outside of Overpass Turbo, it's just a convenient way to share it. You could also compute a bounding box from the coordinate and restrict the search to that area, if that were more suitable for your goal. answered 29 Jul '18, 17:25  maxerickson edited 29 Jul '18, 17:25 showing 5 of 7 show 2 more comments |
The /search endpoint doesn't understand &lat or &lon parameters (only /reverse does), setting &polygon= to 50 has the same effect as 1 and only affects the output. See https://wiki.openstreetmap.org/wiki/Nominatim#Search The closest you can get with Nominatim is using a query 'hospitals near 40.406932,-79.932963'. The 'near' (or 'in') is optional. You can set the &limit=50 to get more results (maximum is 100). The Overpass-API system is more flexible (support more types of point-of-interest, more filters, better control over the search radius) overall. answered 29 Jul '18, 21:45  mtmail I like using the "hospital near 40.406932,-79.932963" method, but at some places it returns nothing. Is there a way to increase the sq miles it checks? (01 Aug '18, 21:26) Dave4784 Nominatim doesn't have a parameter for that. (06 Aug '18, 11:13) mtmail |
Hello. Is something like that available for Nominatim API?
Not beyond what is mentioned in the other answer.
There isn't.
Ok, thanks. Now I want to try Overpass-API. How to send just query using REST API (POST some json url)? And where to get results? Because your example draws on the map, but I want result in text format (json)
Never mind. Found out https://www.overpass-api.de/api/interpreter?data=THE SAME QUERY AS IN YOUR EXAMPLE, BUT EVERYTHING IN ONE LINE
And one more question - how to search for any building/place using any name? So it can be anything, not necessarily hospital. I tried replace "amenity" with "name", but it does't work like with Nominatim API, it excepts name which will match 100%, but I want just normal name query (like we search in Google and in Nominatim API)
Don't add questions to answers. Instead create a new question.
