Google Road Map | Weather | Geocoding: Address => Latitude, Longitude
As we use two different sources for the weather and geolocation purpose, there may be different results on the weather and map. For example, when you enter Pekin, as it's ambiguous, you will get the weather for Pekin in USA, and Google Map indicates the Capital of the China, while you are certainly insterested by Pekin China. So you should supply Pekin China in your query box.
