Re: Google Maps as crude ranging technicque?
Most high definition aerial/images are 1 meter per pixel. Thus if all else is perfect the best one could get is sub 2 meter values. 1 meter at each end of the measurement.
All else is never perfect. With a sub-meter gps receiver, $2000 range, the trace can be kept on the road way, more or less. At times you are shown in the wrong lane.
With any hand held gps if you can get within range of a 22 LR you're in good shape.
Repeatability with hand helds, where differential correction is iffy, is not close to risk a shot at an animal.
LRF is the only way to go with confidence.
