Question

我正在制作Google地球KML，但遇到了麻烦。我的LineString不会留在地上。我认为我在instructed中使用clampToGround作为documentation。

为什么clampToGround不让LineString高于地面？如果我正确阅读文档，它确实应该保持在地面上。我试图通过relativeToGround并给它一点高度来解决它，但这也没有用。我只是想确保线在整个地面上都是可见的。

KML的显着部分：

<Placemark>
        <name>Untitled Path</name>
        <styleUrl>#m_ylw-pushpin</styleUrl>
        <LineString>
            <extrude>1</extrude>
            <tessellate>1</tessellate>
            <altitudeMode>clampToGround</altitudeMode>
            <coordinates>
                86.66797376467392,48.79933074280933,100 87.52400441880934,49.14303840409646,100 
            </coordinates>
        </LineString>
    </Placemark>
    <Placemark>
        <name>Untitled Path2</name>
        <styleUrl>#m_ylw-pushpin</styleUrl>
        <LineString>
            <extrude>1</extrude>
            <tessellate>1</tessellate>
            <altitudeMode>clampToGround</altitudeMode>
            <coordinates>
                86.66797376467392,48.81933074280933,10 87.52400441880934,49.15303840409646,10 
            </coordinates>
        </LineString>
    </Placemark>
    <Placemark>
        <name>Untitled Path3</name>
        <styleUrl>#m_ylw-pushpin</styleUrl>
        <LineString>
            <extrude>1</extrude>
            <tessellate>1</tessellate>
            <altitudeMode>relativeToGround</altitudeMode>
            <coordinates>
                86.66797376467392,48.91933074280933,10 87.52400441880934,49.25303840409646,10 
            </coordinates>
        </LineString>
    </Placemark>

我放大的越多，遮挡的越多，但地面越大。我怎么阻止这个？

即使在放大时绘图，我仍然可以导致这种情况发生：
