Add a reverse lookup of the coordinates to obtain country and city (plus more?)

+1 for this! very much interested!
Edit: Did I put this to test..sorry not intended.

I'd also suggest for normal forward-geocoding to use the data provided by the external geocoding service for filling up missing user input. E.g.: If i type in just "Dallas" as city and leave other fields like postal code empty. The location record will only have the field "city" set, but since this input will be geocoded just fine, why not using the returned address details like zipcode, state etc. to fill the missing fields in the location record?!
@Brandon: I'd code this if you think the idea's good ... should be quite easy.

Would be great to have this in!

exactly, this would have to be optionally.
However, nothing comes back from the geocoder more exact that was put in in the first place, so if e.g no street was input intentionally, the geocoder wouldn't return that information, but it would be of use (e.g. in overviews, postal_code-searches etc.) to have the "default" zipcode written back (the many smaller cities have just one, anyway) or have the unambigous state-information added.
The option to do it this way should be given to the user, of course.

Hi,

Added to above it would be great to have some functions like the _iso functions to be able to get the region from the city and country. Or get the country from the city and region, or get the country from the city only. Not only through user-input, but also automated from the information at hand.
So first maybe if possible:
1a- The country from the lat/lon
1b- The region from the lat/lon
1c- The city from the lat/lon
Then may be:
2a- The region from the country and city
2b- The country from the region and city
2c- The country from the region
2d- The country from the city.

This way with only small information available by the user, or from something like for example a feed the whole location table can be filled with the correct values. And if there is one or two mistakes then user-correction can change these values correct.
Hopefully this input is valuable to this thread.

Greetings,
Martijn

I thought this used to work in the 5.x version of location, but doesn't seem to in 6.x... That is, I had a setup where users entered country and post code, and then I was able to display city, state/province, etc...

Anyway, subscribe!

I marked #327025: reverse lookup and taxonomy as a bit of a duplicate of this issue.

tagging super cool idea

Subscribing. Geocoding to UK counties or regions is my bag.

Funny - i just did this today, out of necessity.
There is no user-interaction, it just overwrites what the user input with the geocoded info, and it changes the way that the geocoding is done(uses JSON from google, instead of XML), but I plan on going further with it at some point.

geodaniel, summit, et al.:

Check out my latest patch on #495690: Change user-inputted address (or lat/lon) to geocoded address info & see whether it satisfies what you are looking for. It builds off furrymitn's work to make it so the user input data is only overwritten when the latitude & longitude are changed.

If the patch does satisfy what you are looking for, I think it might be better for me to re-roll it as a single patch (currently it needs some help - I'm not the best at rolling patches). I might also add an option in the admin, since currently it always does reverse geocoding if the latitude & longitude are changed.

Once re-rolled, I would bring the new version of it over to this issue & we could continue the discussion here. furrymitn's issue seems to be satisfying a slightly different use case (i.e., always overwriting user-submitted data with Google's data, not just when latitude/longitude are changed). But I'm waiting to hear back on whether I am correct about that.

Hi, I am not at home right now. Geodaniel please take the lead, thanks!

Subscribing! I think this reverse geocoding functionality could be very useful.

has this been committed to dev yet?

I don't think that's even on the radar. The functionality is in the linked issues, not this one.

Hi, I managed to integrate the patch at #6 with success - the only thing I'm missing is the automatic fill-in of the address fields on map-click - anyone know if this is possible?

Evan:

shouldn't this thread (and the others you've mentioned) be the ones marked as duplicate of #190578 Reverse Geocoding ?

I'm just asking because the other thread is older than the ones you've mentioned.

Anyway, there's a stand alone module that does this task here. Still under development.

@HLopes: The issue you mention is for the Gmap module, is on the 5.x branch, and has no working patch. My argument is that this kind of functionality should be in Location module in any case, since it is not Gmap-specific.

I'll have to check out the module you linked. Are there plans to eventually add it to Drupal.org?
