Question

我一直试图通过以下方式在Google地图中呈现我的KML服务。

var ctaLayer = new google.maps.KmlLayer({
   url: 'http://DomainName/GeoSystem/redrawKML'
});
ctaLayer.setMap(map);

但是当我检查状态时，我正在使用 ctaLayer对象获得undefined。

但是同样的服务运行良好，如果我试图用geoXML解析器解析KML服务。现在，我很困惑，不知道。为什么我无法使用谷歌地图中的谷歌地图KML图层渲染我的KML服务。

非常感谢任何帮助。

我的Woring代码包含GeoXML库。

var geoXml = new geoXML3.parser({
    map : map,
    singleInfoWindow : true
});
geoXml.parse('http://DomainName/GeoSystem/redrawKML');

以下是我的KML内容，该内容将由我的休息服务（http://DomainName/GeoSystem/redrawKML）

生成

Answer 1

您检查了KML limits of Google Maps API v3吗？如果超过功能数量或文件重量限制，则不会显示任何内容。

修改：我将您的kml上传到我的公共Dropbox文件夹。

我装的很好
var fortw = new google.maps.KmlLayer({ url: 'https://dl.dropboxusercontent.com/u/3133731/fortworth.kml', map: map });

Answer 2

得到了答案。

如果谷歌地图API3的KMLLayer必须显示内容，KML File should be in PUBLICALLY ACCESIBLE。然后，只有谷歌服务器可以解析该文件，并将其在谷歌地图中呈现。

因为我在当地环境中发展。 Google Server can not parse the KML File which i am providing. That is why the contents are not rendered in the Google maps.

为什么我无法在谷歌地图中呈现我的KML服务？
