How to get Geographical coordinates by Google Map API?

I have a list of cities and places, and I want to get their Geographical coordinates. Is there an开发者_开发技巧y api can do it?

This process is called "Geocoding". Here's Google's API for this. There are also several other services that do this listed on the "Geocoding" Wikipedia page.

Google has a limit on the number of requests you can make per day. If you need a higher volume than Google allows, and you can live with lower quality data, you can try USC WebGIS.
