The quality of the data is abysmal. They got what they paid for. They tried to do this on the cheap. Using information that had already been processed instead of taking raw information from a mapping agency and doing their own work. It may have cost them a few $m in licensing with the agencies but it would have been worth it.
Which is contrary to what they claimed on stage.
I said in a previous thread on this, they should have got data from original sources, e.g. USGS, OS and IGN. The maps and basic info would have been excellent. They could have started with a great basic mapping application.
All the additional data could be added in layers over time.
I think many users would be able to live without the additional functionality if the basic information was correct. Sadly not a single layer of the application works properly.
People thinking that this will be any good in a couple of months are deluding themselves. Small areas will be greatly improved, but the wider maps will be dreadful for years.
Google maps is as good as it is because they have had a large work force on it for a long time. Apples belief that they could compete in 12 months with second hand data was deluded at best and down right ignorant at worst.
No, 10.0 was released in 2000, 9.2.1 was released in 2001. Real mac user my arse!
Very curious on how you came to this conclusion. AFAIK, they licensed from reputable map sources. Any it seems that the majority of the issues is with POIs and with the search backend (parsing addresses, etc). Less so with actually having roads show on the map (I came across examples of roads in Brazil that Apple has and google doesn't, and vice versa.)
Your post is interesting, but it would be great to understand if you are making assumptions or if this is based on your observation of actual data.

Almost 100% of locations coming from Yelp are way off in my town - so it could have been an issue when they merged with the Yelp data.
That's what I see as well. Somehow, the merge of POIs onto the map layer got borked. POIs are often there, but slightly off (within the block, or many blocks away). I see that in many places in NYC. Could be that someone forgot to "center" the map before hitting "export"
