geocoding - 需要帮助查找特定邮政编码的 KML 数据

Question

我正在使用新泽西邮政编码制作热图，但我使用的几何信息对于两个邮政编码是不正确的。有谁知道我可以去哪里获取这两个特定邮政编码的 KML 信息？我在这里看到了很多关于将哪些资源用于 KML 数据的帖子，但它们非常先进，我不知道如何挖掘论坛上其他人链接到的数据库。

具体来说，我需要邮政编码 08559 和 08757 的 KML 邮政编码数据。以下是这些邮政编码的有缺陷的 KML 数据:

08559:

<Polygon><outerBoundaryIs><LinearRing><coordinates>-74.892528,40.414294,0.0 -74.967386,40.39857,0.0 -75.060361,40.420788,0.0 -75.064463,40.500774,0.0 -75.06583,40.517523,0.0 -75.068223,40.457705,0.0 -74.991314,40.481632,0.0 -74.88911,40.47001,0.0 -74.892528,40.414294,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon>

08757:

<Polygon><outerBoundaryIs><LinearRing><coordinates>-74.190432,39.946002,0.0 -74.221537,39.932329,0.0 -74.322374,39.946002,0.0 -74.234185,40.008896,0.0 -74.26905,39.986678,0.0 -74.206839,39.952154,0.0 -74.19761,39.949762,0.0 -74.190432,39.946002,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon>

如何创建具有多个邮政编码的区域 map

1. 从 census.gov 下载包含所有美国邮政编码的 KML 文件。本网站上最新的文件是:http://www2.census.gov/geo/tiger/GENZ2015/kml/cb_2015_us_zcta510_500k.zip。如果此链接已损坏，请在 Google 中搜索 site:census.gov KML ZIP。另一种选择:https://www.filosophy.org/post/17/zipcodes_in_kml/

1. 在纯文本编辑器中打开这个巨大的 (175MB) 文本文件，搜索您想要的邮政编码并复制 <Polygon> 部分。这是搜索 >94117 时的结果:

   <Placemark id="cb_2015_us_zcta510_500k.kml">
   <name>&lt;at&gt;&lt;openparen&gt;&lt;closeparen&gt;</name>

1. 创建一个干净的 KML 文件并将 <Polygon> 移至此文件。下面是一个包含两个邮政编码多边形的 KML 文件 ( service-delivery-area.kml ) 示例。 Google 有很棒的 KML Reference 。

1. 前往 https://www.google.com/mymaps/ 并创建一张新 map 。单击“添加新层”，然后单击“导入”，并上传您的 KML 文件。如果多边形不正确，您可以在 map 上编辑多边形。

1. 你的 map 应该有这样的结果:https://www.google.com/maps/d/u/0/embed?mid=1zop5GMD1b2afmOvObQIi7YvF1d4
