It's a great technique and I've used it myself on many occasions. However, where I live we have forests of trees that grow a bit tall. Well, quite tall. Like, taller than the entire Statue of Liberty from the base of the pedestal to the top of the torch.qwaletee wrote:As to SV and Sat shifts, I did once check on this. SV pictures are taken with GPS coords, and I found they generally matched up with what Waze records for a drive.
The ones that were THAT tall are nearly all cut down now, but even the "little" ones are pretty impressive. They make a big impression on the GPS signals that's for sure. I've found that SV position data is not that reliable in some of these forests.
But it can still be useful to get an idea of how the road turns, and you can use that with occasional glimpses of asphalt to register the track.
