If you go back over this blog and follow my recounting of the history of Google's attempts at developing a quality mapping service, you will notice that they initially tried to automate the entire process and failed miserably, as has Apple. Google learned that you cannot take the human out of the equation. While the mathematics of mapping appear relatively straight forward, I can assure you that if you take the informed human observer who possess local and cartographic knowledge out of the equation that you will produce...a failed system (emphasis added).
