Receive a WOEID by Lat, Long with Yahoos API

Question

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?

Answer 1

Yahoo! PlaceFinder API allows you to find a corresponding WOEID for a latitude/longitude pair. Consider this example web service method call:

http://where.yahooapis.com/geocode?location=37.42,-122.12&flags=J&gflags=R&appid=zHgnBS4m

You can play with request parameters according to your needs, see Yahoo! PlaceFinder API documentation for more. And you should replace appid with your Yahoo! appid, you can create one here.

This request returns a response like that, which includes a lot of useful data along with the WOEID:

This is now available through the recently released PlaceFinder API. Kudos to Yahoo! for providing yet another important piece of the Geo puzzle.
