地理编码数据库 [英] Geocode database

我可以下载地址，城市，州，邮政编码-纬度/经度信息，这些信息可以单独加载到美国数据库中.也请对其准确性和覆盖范围发表评论.

我想所有的GPS设备都可以做到这一点.任何可以提取此信息的指针?

I suppose all GPS devices do this.. any pointers where I can extract this info??

我尝试了google maps json api ..，但不喜欢它们限制每秒请求数的想法.

I tried google maps json api.. and don't like the idea that they rate limit the number of requests per second..
