为什么 HERE 地理编码器 API 会得到 return 与 HERE 地图搜索不同的结果？

Question

给定一个示例地址，我从 HERE Geocoder API 返回了一个不准确的结果。但是，如果我在 HERE 地图网站 (https://maps.here.com/) 中输入相同的地址字符串，它似乎会正确放置地址。

HERE 地图网站没有使用相同的后端定位服务吗？

我的示例字符串：800 W Miner St, West Chester, PA 19382

如果您转到地图站点并搜索该字符串，它会在 Google 放置它的位置附近返回。但是 Geocoder API 返回下面的通用 "center of the city sort of near the street" 响应。

我会把它归结为错误的输入并继续，但奇怪的是地图网站返回的结果与 API 不同 - 我认为他们会做类似的工作。

是否有 API 用于地图站点查找位置的方法？或者有什么方法可以调和这两个不同的结果？

Answer 1

here.com 是一个定制的应用程序，我相信为了提供建议 here.com 首先使用 Places API 而不是 Geocoder
