Question

我有一个KML文件，我将其复制/粘贴在一起，形成如下所示的融合表：

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1">
<Document>
<Polygon><outerBoundaryIs><LinearRing><coordinates>-73.992177,40.743465,0.0 -74.008242,40.752352,0.0 -74.006533,40.756112,0.0 -73.983973,40.748934,0.0 -73.987733,40.744149,0.0 -73.992177,40.743465,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon>
<Polygon><outerBoundaryIs><LinearRing><coordinates>-73.973035,40.689458,0.0 -73.989784,40.683305,0.0 -74.008242,40.686381,0.0 -73.978846,40.705181,0.0 -73.977479,40.698003,0.0 -73.973035,40.689458,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon>
(...)
</Document>
</kml>

据我所知，在地图上绘制这些内容就像

一样简单

var zipoverlay = new google.maps.KmlLayer('zips.kml');
zipoverlay.setMap(map);

但显然这没有任何作用。它不像我想象的那么神奇吗？

谢谢！

Answer 1

感谢Dr.Molle，我们想出了这一点。这就是我做错了：

需要从我自己的机器外部访问KML文件。在其他地方托管它，以便地图能够抓住它
KML文件的结构必须如下：

`

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.2">
<Document>
<Placemark>
<Polygon><outerBoundaryIs><LinearRing><coordinates>-73.992177,40.743465,0.0 -74.008242,40.752352,0.0 -74.006533,40.756112,0.0 -73.983973,40.748934,0.0 -73.987733,40.744149,0.0 -73.992177,40.743465,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon></Placemark>
<Placemark><Polygon><outerBoundaryIs><LinearRing><coordinates>-73.973035,40.689458,0.0 -73.989784,40.683305,0.0 -74.008242,40.686381,0.0 -73.978846,40.705181,0.0 -73.977479,40.698003,0.0 -73.973035,40.689458,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon>
</Placemark>
</Document></kml>

Answer 2

<Polygon/>必须是<Placemark/>或<MultiGeometry/>的孩子，而不是<Document/>

的孩子

Answer 3

我的错误是在我的服务器上启用了HTTP身份验证，这阻止了Google请求KML文件。我想这不是客户端。

Answer 4

我遇到了此类问题（kml层未显示），因为网址（或可能只是文件名）太长。使用较短的网址即可正常工作。

Google Maps API V3：KML图层没有显示？
