问题描述
我手工创建了这个.kml文件，概述了美国新罕布什尔州的一个地区。它可以很好地在Google mymaps中加载，但是如果我将其加载到Google Earth中，则显然会放置在“空岛”（纬度0，经度0）上。该文件怎么了？

谢谢
解决方法
KML coordinates are longitude,latitude;不允许有空格。
您的KML应该是：
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0"> <Document>
<Placemark>
<LineString>
<coordinates>
-71.21122,43.25277,0.
-71.20669,43.24993,0.
-71.20720,43.24918,0.
-71.20512,43.24787,0.
-71.20566,43.24733,0.
-71.20576,43.24718,43.24557,0.
-71.20763,43.24572,0.
-71.20746,43.24666,0.
-71.20855,43.24638,0.
