I was recently exploring the capabilities of Bing Maps, when I discovered that it could be used to calculate the area of a field or pond. Landowners often need an easy way to calculate the area of a field. Here's a video showing how to navigate to Bing Maps, and then how to calculate the area of a field, or in this case, a pond.
If you want to see the video with all the detail of what is being done on-screen, choose the 720HD option in the lower part of the screen and also turn on the "full screen" mode. That way, it will be full screen instead of a small window. Here's the link to the video, or you can click on the video above.
