寻找特定邮政编码的KML数据需要帮助

我正在使用新泽西州邮政编码制作热力图，但我使用的几何信息对于两个邮政编码是不正确的。 有人知道我在哪里可以获取这两个特定邮政编码的KML信息吗？ 我在这里看到了很多关于KML数据使用什么资源的帖子，但它们都非常高级，而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08559和08757邮政编码的KML邮政编码数据。以下是我对这些邮政编码拥有的有缺陷的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>
这是一个地理信息系统的问题。这里不是提问的正确场所... - s-m-e

如何创建一个包含多个邮政编码的区域地图

  1. 从census.gov下载包含所有美国邮政编码的KML文件。该网站上最新的文件为：http://www2.census.gov/geo/tiger/GENZ2015/kml/cb_2015_us_zcta510_500k.zip。如果该链接已失效，请在Google上搜索site:census.gov KML ZIP。另一个选项是：https://www.filosophy.org/post/17/zipcodes_in_kml/


  1. Open this huge (175MB) text file in a plaintext editor and search for the zip code you want and copy the <Polygon> section. Here is the result when searching for >94117:

    <Placemark id="cb_2015_us_zcta510_500k.kml">

  1. Create a clean KML file and move the <Polygon> to this file. Below is an example of a KML file (service-delivery-area.kml) with two zip code polygons. Google has a great KML Reference.

  1. 前往https://www.google.com/mymaps/并创建一个新地图。点击“添加新图层”，然后点击“导入”，上传KML文件。如果多边形不正确，您可以在地图上编辑多边形。


  1. 您的地图应该像这样显示：https://www.google.com/maps/d/u/0/embed?mid=1zop5GMD1b2afmOvObQIi7YvF1d4

“您可以在一个目录中轻松搜索和下载任何邮政编码、县或州的人口普查KML边界文件。
个别邮政编码KML 以下是您提到的2个邮政编码的KML文件链接： https://census.simplecrew.com/us/zip-codes/08559 https://census.simplecrew.com/us/zip-codes/08757”

所有邮编按县分类的KML文件
您甚至可以下载一个包含所有县的邮编的单个KML文件。例如，您的两个邮编分别位于亨特登县和欧申县：
https://census.simplecrew.com/us/states/nj/counties/hunterdon/zip-codes
https://census.simplecrew.com/us/states/nj/counties/ocean/zip-codes

所有邮编按州分类的KML文件
此外，您也可以在这里下载一个包含新泽西州所有邮编的单个KML文件，而不是自己创建地图： https://census.simplecrew.com/us/states/nj/zip-codes

针对美国邮政编码，美国人口普查局提供了相关数据： http://www.census.gov/geo/www/cob/z52000.html#ascii

下载新泽西州或其他50个州的ASCII数据集。

您可以在小文件（例如zt34_d00a.dat）中查找您的邮政编码索引。

 317
 "08559"
 "08559"
 "Z5"
 "5-Digit ZCTA"

然后在大文件中找到匹配的经纬度坐标列表。

第一个值是经度，第二个值是纬度，都以十进制度数表示。

注意，一些点可能会错乱（或错误），因此在转换为KML后您可能需要清理它们。一个有用的工具来帮助调试点并删除错误点是KML Number-the-points tool，它生成KML Placemarks，每个标签对应于给定输入中线或多边形中的每个点。如果有长列表的点并且需要轻松识别它们，则非常有用。
