创建KML路线

Question

我正在尝试创建一个基于lon＆amp; amp;的路由LAT的。这是我到目前为止所做的，但它似乎没有正常工作。

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2"> 
<Document>
  <PlaceMark>
    <name>test</name>
    <description>test Desc</description>
    <Point>
      <coordinates>-80.54400115,43.4250264</coordinates>
      <coordinates>-80.52674314,43.43127701</coordinates>
      ...
    </Point>
    </PlaceMark>
  </Document>
<kml> 

语法是否正确？当我在我的地图应用程序中加载它时，它不显示路线。

Answer 1

请参阅KML reference

1. KML是区分大小写的XML（PlaceMark与Placemark不同）
2. <Point>是一个单一的位置
3. 一行是<LineString>
4. 您的XML必须有效（关闭开头</kml>需要<kml>）。

example

KML from example above on Google Maps
