我有一个地址字符串“12 Swiss Ave, Gonville, Wanganui, New Zealand”

鉴于此地址，我需要确定该地址是在新西兰的北岛还是南岛。

如果我将地址传递给 google maps api，我得到的数据在下面，不幸的是，虽然它没有告诉我它在哪个岛上。那么，我该如何检查呢？

最佳答案

一种选择是获取两个岛屿的多边形，并在多边形分析中对地理位置进行点分析。

Example using Polygons defined by KML和 geoxml3

Proof of concept (使用来自 gadm.org 的 geoxml3 和修改后的 KML)

============ 使用融合表的旧选项，不再有效 =============

Example using FusionTables (注意不再有效，Fusion Layers 已于 2019 年 12 月关闭)

Proof of concept (使用 Fusion Tables 中的自然地球数据集和“州到岛” map )(注意:也不再有效)
