【问题标题】：Need help finding KML data for specific ZIP code需要帮助查找特定邮政编码的 KML 数据

【问题描述】：

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不正确。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 KML 数据使用哪些资源的帖子，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>

这是一个 GIS 问题。问错地方了……

【解决方案1】：

对于美国邮政编码，可以从美国人口普查中获得数据： 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的索引

 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。

317      -0.749719256389896E+02       0.404391641604938E+02
      -0.750611840000000E+02       0.404766960000000E+02
      -0.750607720000000E+02       0.404766880000000E+02
      -0.750620530000000E+02       0.404692640000000E+02
      -0.750637010000000E+02       0.404652440000000E+02
...
      -0.750622670000000E+02       0.404709200000000E+02
      -0.750611840000000E+02       0.404766960000000E+02
END

第一个值是经度，第二个值是纬度，都是十进制度。

注意某些点可能有问题（或错误），因此您可能需要在转换为 KML 后对其进行清理。 KML Number-the-points tool 是帮助调试点和删除坏点的一个方便工具，它生成 KML 地标，每个地标带有对应于线或多边形中的每个点的数字标签，给定一些 KML 作为输入。如果有很长的点列表并且需要轻松识别它们，则很有用。

如何创建具有多个邮政编码的区域地图

从census.gov 下载包含所有美国邮政编码的 KML 文件。该站点上的最新文件是：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 上搜索 site:census.gov KML ZIP。另一种选择：https://www.filosophy.org/post/17/zipcodes_in_kml/

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：

创建一个干净的 KML 文件并将 <Polygon> 移动到此文件。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。谷歌有一个很棒的KML Reference。
