[Feature Request] Lookup by id (GoogleMapsProvider, Nominatim)

[franzwilding]

First of all, thanks for this great php package!

I have a feature request for getting address information by id instead of doing a full search again. I think many applications will store part of the geocoding response and eventually will re-fetch information for the stored part.

At the moment, with GoogleMapsProvider and NominatimProvider you can only do a reverse lookup by lat/lng or re-do the query. However both of the endpoints have a dedicated API for lookup (for google maps this even is the preferred way, because it will not count as a request as far as I know).

For OpenStreetMap it looks like this: https://nominatim.openstreetmap.org/lookup?osm_ids=NXXXXX.

It would be great if the providers would have a lookup method for this. An even better solution would be to extend the provider Interface (or have a 2nd interface "LookupAwareProvider" with a lookup action or the GeocodeQuery object with an id property and maybe also the Location interface.

If a provider defines an id for a location, it could be used for a lookup call.

I know, that I can easily achieve this by creating my own provider, however, if this feature is interesting for you, we could discus an solution and I could provide a PR for this.

Hello @franzwilding ,

That's indeed (IMHO) a good idea ! I think we could add it to our Geocoder Interface rather easily.

What do you think about this @willdurand @Nyholm ?

Hey @jbelien,

I think an even better solution would be to extend the Gecoder Interface with an id-aware-geocoder interface, because some geocoders will not support an id, I guess?

[jbelien]

You're right but that's not an issue.

Some providers do not support reverse geocoding either (have a look at AlgoliaPlaces for instance). For consistency, I would add a lookup function to the standard Geocoder interace.

Ok cool. I will try to find time to create a PR for this!

[franzwilding]

@jbelien I finally found some time and implemented a first draft of the lookup action. in https://github.com/geocoder-php/Geocoder/pull/979. Once jenkins runs, we can see if this is a good solution

Thanks a lot @franzwilding ! 👍 I'll have a look at it as soon as possible.
