我正在阿根廷实施具有不同路线的自定义 KML。

我想显示我的自定义扩展数据，但不起作用。有人可以告诉我有什么问题吗？

这是我的代码 KML

这是我的 KML 代码，这就是我在 MyMaps 中尝试的结果

这是谷歌给我看的结果：

您看到的问题是 KML 无效。KML 中的标签区分大小写。KML使用大小写混合的标签，有时以大写字母和其他时间小写（例如，启动<Data>，<value>等等），所以你必须确认正确的语法。在Google 地球专业版中显示 KML可能有助于检查它是否正确并按预期显示。

所述<Value>元件必须是小写<value>和StyleUrl元件必须以小写字母开头; 即<styleUrl>。

将地标更改为如下所示：

<Placemark>
    <name>Ruta PROV. 63 - SAN JUAN</name>
    <styleUrl>#info_rutas_arg</styleUrl>
    <ExtendedData>
        <Data name="id_lugar">
            <value>2806</value>
        </Data>
        ...
</Placemark>

同样出于某种原因，文档父容器上的描述阻止了地标显示，因此建议从文档中删除描述元素或仅将其注释掉。
