geolocation

Hi,

I want to make a apps that check what's the nearest place from where the user is. I can easily get the location of the user and I have a list of places with latitude and longitude.

What would be the best way to know the nearest place of the list against the current position.

I could not find anything in the google APIs.

I am worried I need to resort to my calculate and have to do math to calculate it.

What do you guys think ?

Cheers and thanks for reading or replying.
