For a web app I'm working on, I need to know the lat/lon of about 300 US cities. I also need to know the lat/lon for every US zip code.
对于我正在研究的网络应用程序,我需要知道大约300个美国城市的纬度/经度。我还需要知道每个美国邮政编码的纬度/经度。
Does anyone know of a free source to get this information?

There is an online database at Geocoder.us. And a simple perl module (we added a soap service to this so we could simply access it from any language, and the longest part of the development process was downloading database (it's about 4 GB).) The geocoing database is available from the US census bureau, a good article on getting this setup can be found here.
