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
- 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/
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><at><openparen><closeparen></name> <visibility>1</visibility> <description><![CDATA[<center><table><tr><th colspan='2' align='center'><em>Attributes</em></th></tr><tr bgcolor="#E3E3F3"> <th>ZCTA5CE10</th> <td>94117</td> </tr><tr bgcolor=""> <th>AFFGEOID10</th> <td>8600000US94117</td> </tr><tr bgcolor="#E3E3F3"> <th>GEOID10</th> <td>94117</td> </tr><tr bgcolor=""> <th>ALAND10</th> <td>4373059</td> </tr><tr bgcolor="#E3E3F3"> <th>AWATER10</th> <td>1625</td> </tr></table></center>]]></description> <LookAt> <longitude>-102</longitude> <latitude>38.5</latitude> <range>7000000</range> <tilt>10</tilt> <heading>0</heading> </LookAt> <styleUrl>#KMLStyler</styleUrl> <ExtendedData> <SchemaData schemaUrl="#kml_schema_ft_cb_2015_us_zcta510_500k"> <SimpleData name="ZCTA5CE10">94117</SimpleData> <SimpleData name="AFFGEOID10">8600000US94117</SimpleData> <SimpleData name="GEOID10">94117</SimpleData> <SimpleData name="ALAND10">4373059</SimpleData> <SimpleData name="AWATER10">1625</SimpleData> </SchemaData> </ExtendedData> <Polygon> <extrude>0</extrude> <tessellate>1</tessellate> <altitudeMode>clampToGround</altitudeMode> <outerBoundaryIs> <LinearRing> <coordinates>-122.477297,37.766069,0 -122.477379,37.765482,0 -122.458405,37.76616,0 -122.45779,37.766015,0 -122.457536,37.763566,0 -122.455999,37.763904,0 -122.456994,37.761842,0 -122.459173,37.761912,0 -122.455944,37.760239,0 -122.456603,37.759235,0 -122.454002,37.758785,0 -122.451817,37.759453,0 -122.447682,37.75919,0 -122.446783,37.761781,0 -122.445309,37.76188,0 -122.442915,37.763648,0 -122.443347,37.765333,0 -122.441242,37.765271,0 -122.4382,37.767159,0 -122.435624,37.767328,0 -122.435794,37.769058,0 -122.429128,37.769456,0 -122.428426,37.770452,0 -122.429178,37.774181,0 -122.429929,37.777909,0 -122.430115,37.778842,0 -122.444967,37.776958,0 -122.44478,37.776017,0 -122.446471,37.775802,0 -122.446846,37.777669,0 -122.453188,37.776853,0 -122.45281,37.774995,0 -122.463749,37.773624,0 -122.464611,37.77244,0 -122.459162,37.771314,0 -122.459901,37.770442,0 -122.464402,37.769669,0 -122.467004,37.768013,0 -122.469758,37.769209,0 -122.472245,37.76861,0 -122.473124,37.767116,0 -122.477297,37.766069,0 </coordinates> </LinearRing> </outerBoundaryIs> </Polygon> </Placemark>
创建一个干净的 KML 文件并将
