Reply to "Google Earth Useful Tip"

Pete sent me a couple different course paths from people who measured this course with google earth. I opened those up in GE in order to compare to my path. Below is a small section of that


My path is shown and blue. I was very surprised to see my path not follow the corners at all. Around one corner I'm in the grass, and around the other I'm out in the middle of the road. Then I remembered that I used an older image when I drew my path. Below is the same paths on the winter imagery of 2012.


The measurements from these 3 paths were within a few feet of each other, so using either the 2013 or the 2012 imagery results in a good measurement. Apparently the image is just shifted slightly between the two. But the lesson learned here is that you should pick one image for your path measurement and stick to it, rather than switching back and forth on different corners.
