Apple Maps is a terrible application. The Interface is fantastic but the underlying data is hit and miss.
An example of an address that Apple Maps will find is: 8-10 Edgar Street Stonnington Victoria 3146 Australia. All the information is there so that there is no confusion whatsoever. In theory, Apple Maps pinpoints the location. In reality, it has missed the mark and identifies the wrong end of the street. That is a good outcome with Apple Maps because at least it gets you in the right street in the right part of town.
It appears that Apple Maps has been created by people simlar to the defenders of Apple Maps on this thread. They have taken the "near enough is good enough" attitude to its implementatioin. If I wanted a product of that quality, Id buy Samsung. Unfortunately, it appears that the Apple company is lowering its own very high standards. This is not a failure like any of the others Apple has had in the past. This is an instance of core functionality sacrificed in a release. The end customers user experienced has been severly diminished.
There are many people here running to the defence of Apple Maps. And im happy for all of you who love Apple Maps and rely on it with confidence to navigate you to locations with Google-like accuracy. Here in Melbourne Australia, Apply Maps is junk and you can not rely on it if you want a reliable navigation application, period.
Again, anyone heading to a highly important engagement, be it a business meeting, taking someone to hospital, etc, and the place they are heading is completely and utterly unfamiliar would be negligent to be relying on Apple Maps. In my 3 years experience of using Google Maps, I would with confidence, use it to navigate me to any location with pinpoint accuracy.
