在Googe Maps上测量距离
如果你想测量一下两个或多个地方之间的距离，Google Maps 将是非常有用的。
需要做的是，到“My Maps”标签，从侧边栏选中“Distance Measurement Tool”，在地图中新建一个路径。你可以添加多个点，只是你想要；如果你单击错误了，这里有一个选项来删除最后一个点。
在“My Maps”标签，你也可以创建自定制地图。创建一个新的地图，在地图上单击一个小的图标可以新增一条线。在定义好线路后，你可以通过拖拽此线路上的一个白色的矩形来改变它。自定制的地图可以被保存，以便将来引用、打印、与其他人共享或嵌入到你的博客中。
比较这些距离以及它们所含有的驾驶方向是有趣的。在侧边栏可以定义线路，拖拽蓝线或者添加新的目的地。
Google Earth提供了相似的方式来测量距离。包括Google Maps 和Google Earth，“测量是使用lat/lon坐标来计算的两点之间的距离，没有考虑海拔”
关于距离的测量单位，你可以选择公制还是英制。在“My Maps”中的路线显示了总的里程数，然而驾驶方向显示了一个国家所使用的测量单位。
Measuring Distances in Google Maps
If you want to measure the distance between two or more places, Google Maps can be pretty helpful.
One way to do that is to the "My Maps" tab, select "Distance Measurement Tool" from the sidebar and create a path on the map. You can add as many points as you want and if you make a mistake, there's an option to delete the last point.
In the "My Maps" tab, there's also the option to create personalized maps. Create a new map and add a line by clicking on the small icon from the map. After you define the path, you can change it by dragging one of the white rectangles placed on the path. The personalized map can be saved for future reference, printed, shared with others and embedded in your blog.
It's interesting to compare these distances with those obtained from driving directions. To customize the route, drag the blue line or add a new destination in the sidebar.
Google Earth offers similar ways to measure distances. In both Google Maps and Google Earth, "measuring is calculated using the lat/lon coordinates from point to point and does not consider elevation."
Only the distance measurement mapplet lets you choose between metric and English units of measures. The path from "My Maps" shows the total distance in miles, while the driving directions show the units of measures used in a country.
