i searched a while but found nothing, thats simular to my problem.
i'm trying to use the YAHOO Weather API, for example: http://weather.yahooapis.com/forecastrss?w=4097
i don't know the WOEID in my case, but i got latitude and longitude points.
so my question is: is there a way to get the WOEID of a place by using lat and long points?
This is now available through the recently released PlaceFinder API. Kudos to Yahoo! for providing yet another important piece of the Geo puzzle.
