I know that he used directions and elevations.
He told me that his use case was definitely NOT free.
I also know that Apple Maps could not give him the specializations he was looking for. He is an experienced, rational engineer, and would not have acted in an alarmist manner. He really liked the Google API. Google has done a wonderful job with their map product, but I also know that it's a "gateway drug."
I won't link to his app, because it can get crazy, with all the anti-Apple stuff. I won't drag him into the fray.
