Using Latitude & Longitude to get a place with Yahoo

I am using Google Map API to add markers to a map when the user clicks a location on the map. I want to add an info window for the new marker when its clicked, the info window will be populated with details of the location. The Google map API returns the latit开发者_JAVA百科ude and longitude so I just need a way of taking this info and getting a location.

Is it possible to use Latitude & Longitude with Yahoo Geo Technologies to pinpoint a city or town?

Using YQL, u can obtain a list of possible forecast First step: Reverse geocoding

SELECT woeid 
FROM geo.places 
WHERE text="##LATITUDE##, ##LONGITUDE##"

then apply a filter to order results by placeType. This help U to order forecast by map level accuracy (town, city, postal code, region, ....)

SELECT woeid 
FROM geo.places
WHERE text="##LATITUDE##, ##LONGITUDE##" | 
SORT(field="placeTypeName.code")

Now use simile join to get all forecasts by woeid resulted by last query and filter null results

SELECT channel 
FROM weather.woeid 
WHERE w in (
    SELECT woeid 
    FROM geo.places 
    WHERE text="##LATITUDE##, ##LONGITUDE##" | 
    SORT(field="placeTypeName.code")) 
AND channel.location IS NOT NULL and u="c"

Google has a reverse geocoder, you should use that. why do you need yahoo for that?
