[GIS] How to implement place auto-complete using nominatim

nominatimopenstreetmap

I want to auto complete like Google Place but I don't want to use Google Place API. I got nominatim auto-complete example but it's not working in Windows 8 because it's implemented in node.js

Can anyone help me?

Using Nominatim for for Autocompletion might be not the best idea. If you using the osm.org nominatim Server the usage policy forbid using Nominatim for Autocompletion:

Auto-complete search: This is not yet supported by Nominatim and you must not implement such a service on the client side using the API.

Also it is not really useful to use Nominatim for autocompletion, because if you type "Ber" you would expect something like "Berlin" but Nominatim searches for places exactly known as "Ber" and suggests "Ber, Tombouctou, Timbuktu, Mali".

But there are some OpenStreetMap based geocoders with autocompletion support like Photon and Pelias (Demo). There are usage examples on the project sites.

It says: The AppKey submitted with this request is invalid.

MapQuest changed their licensing model. Since Sep 15th, 2015, they require a valid API Key for their services. For more information read the related blog entry.

If the plugin doesn't offer a method for entering your own AppKey (or a custom Nominatim URL) then you will have to wait for the plugin to get updated.

I guess the relationship is a bit tricky to discover. In fact i guess there is no relationship in the sense of OSM: I mean your building is not referenced as a member of the University of texas relation.

In a reproducible perspective, what you can do I such a case could be to perform an overpass query, based on the attribute fetched from the Nominatim reverse geocoding query. E.g. here Nominatim tells you that this building has university for value ? So lets perform a query to know which university it is :

[out:json];
(
  relation["amenity"="university"](around:5000,30.2814,-97.73883);
);
out body;
>;
out skel qt;

Request result on overpass turbo

Or you can perform a new Nominatim query, as previously, based on relevant attributes fetched from the first query (like University, Austin, Texas) and see if there is something interesting: Result on Nominatim
