想改进这个问题吗 更新问题,使其成为堆栈溢出的主题。

我想要一些关于高容量地理编码API的建议。到目前为止,我已经联系了谷歌和雅虎。谷歌想用太多的钱换取太少的产品,而雅虎没有商业产品。

最初,我每天需要对大约250000个项目进行地理编码,但在不久的将来,这个数字将呈指数级增长,所以我需要一个与我们一起增长的解决方案。

有什么想法吗?

问题回答

有许多提供商提供批量和/或批量地理编码。您也可以购买数据集,具体取决于您的准确性和覆盖区域要求例如,微软提供了一个解决方案。我不能保证它的质量。

我会按喇叭SimpleGeo,看看可以达成什么样的交易;他们是一家初创公司,很可能渴望大量业务。

否则,我可能会开始寻找来源,而不是像谷歌这样的经纪人,例如TeleAtlas,但这肯定会很痛苦。

如果你的每日数字将以指数形式大于250K,例如1.5e+16,你一定会重复很多查询;找到一种方法来清理/规范化它们,以增加缓存命中率并将它们推送到memcached以关闭第三方查询。

这是一个有用的资源,在寻找获取TIGER数据的方法时偶然发现,这些数据必须是免费的,但仅限美国:http://www.vterrain.org/Culture/geocoding.html

One comment on simplegeo , their api is simple and the you can query large number of records in a very short term . But their geo coding quality is not as good as Google or even Bing. I had many cases where I got the same coordinates for different set of addresses. I m looking for a solution my self and I m testing the MapQuest api , seems like there is not rate limit (per say).
