    How accurate is pinned lat & long on Google Earth?
    From: David Pike
    Date: 2017 Feb 26, 11:21 -0800

    I’m working on a learning game for students, but I need to know the lat & long of at least one point to decimetre accuracy.  To save trying to borrow a survey grade GNSS receiver and learning how to use it, could I just pick a point on max scale Google Earth, e.g. the corner of a patch of concrete, and pin that.  It appears to give a lat & long to 6 decimal places of degrees or about four inches, but how accurate is the lat & long really likely to be.  (Ignoring all that clever stuff about places having more than one lat & long)  Would it be more accurate than relying on using a $100 GPS/Glonass/EGNOS embeded hand-held receiver?  Thinking of the extra steps involved, I suspect not, but I would be pleased to be persuaded otherwise.   DaveP
