如何检查Google Maps API区域内的地址

Question

我有一个地址字符串，例如“新西兰旺加努伊，贡维尔，12 Swiss Ave”

鉴于此地址，如果该地址在新西兰的北岛或南岛之内，我需要计算出来。

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

Answer 1

一种选择是获取两个岛的多边形，并在地理位置上进行多边形分析。

[Example using Polygons defined by KML和geoxml3

[Proof of concept（使用geoxml3和来自gadm.org的经过修改的KML）]

============使用融合表的旧选项，不再起作用=============

Example using FusionTables（note：不再起作用，Fusion Layers在2019年12月被拒绝）]

Proof of concept（使用Fusion Tables中的自然地球数据集和“州到岛”地图）（注意：也不再起作用）
