The iOS 6 Review: Maps Thoroughly Investigated and More
by Brian Klug & Saumitra Bhagwat on September 19, 2012 2:21 PM EST3D Flyover
New in Maps is the 3D flyover feature which is limited in iOS 6 to devices with an A5 SoC or better. This means the iPhone 4 (GSM and CDMA), iPhone 3GS, and iPod Touch 4th Generation get excluded from the 3D buildings experience. 3D buildings already taxes the 4S considerably and drops frames from time to time, so I can see why the 4 and 3GS didn’t make the cut. 3D buildings on the iPhone 5 is completely fluid 60 fps, it seems.
On applicable devices, there’s a 3D button alongside the location indicator (which snaps to your present location or toggles compass mode) which toggles a perspective tilt. If theres a region in the current view with 3D building data and you’re at a sufficient zoom level, this changes to an icon with buildings, and tapping enables 3D building rendering. On excluded devices without the right SoC you simply don’t see this toggle at all and can’t two-finger tilt.
NYC was recently added to the iOS 6 3D Maps dataset
These buildings generated using aerial captures as I touched on earlier, and pop in with dynamic Level of Detail (LoD) both for geometry and textures. If you’ve used Google Earth on a mobile device and seen the 3D buildings Google has and the way they pop in, you’ll instantly know what I’m talking about. Generally the geometry starts very smoothed, and Apple has done a good job in iOS 6 of keeping visible switching around between levels hard to notice.
When it comes to evaluating the detail and quality of 3D buildings, the difficulty ultimately lies in selecting the right features to compare. I suspect Apple is also doing some hand massaging of building geometry in some of the more notable urban centers, something Google has told me they do as well, in addition to the user-contributed sketchup buildings. Thus, comparing notable landmarks gives an idea for the best case but not the empirically derived geometry that makes up most of the dataset. Of course in the dense urban environment reconstructing geometry and imagery requires a lot more hand massaging because of occlusions and other considerations.
Cities like Chicago are stunningly detailed.
The level of geometry detail is mostly great in the markets that I checked out. Trees and other geometry which isn’t like a building also gets represented, though some palm trees end up looking like elongated lightbulbs at times. It isn’t always perfect though.
A trouble building I found while making a cursory inspection of Los Angeles. Update: The building actually looks like this (Google Maps) as pointed out by a commenter. Still, it's possible to find buildings with strange geometry and textures applied in iOS 6.
I’ve browsed a lot of buildings which aren’t noteworthy landmarks or part of a city skyline and seen some interesting geometry and texture interpolation errors. Thankfully they’re not super common, and not even Google’s 3D database is free of them, so it’s nothing I hold against Apple’s crew.
The other question then becomes how many cities actually have 3D buildings available from Apple. To find out I manually checked the top 100 most populated cities in the USA and top 30 globally, and made a huge spreadsheet. Unfortunately as of my checking there really aren’t that many markets at all. In fact, it isn't much of a stretch to say that Apple's 3D buildings database is actually very limited at the moment, and basically only includes the USA.
Internationally, none of the top 30 cities have any 3D buildings. In fact, the only international 3D support that I’m aware of is a small region around the Sydney opera house, the Colosseum in Rome, and parts of London in the UK. I was actually surprised to see London get added into the dataset right for the iPhone 5 keynote, as I had checked and seen it was absent just a day before.
In the US, 26 or so cities have 3D building data as of this writing. For the number of the cities which do have it, it tends to be a small grid localized around the densest urban area, which isn’t surprising. Apple doesn’t seem to have prioritized its launch markets by population either, and there are some fairly notable exclusions as well.
Hopefully Apple continues building this dataset out at a good pace, because at present the dataset for 3D buildings and acceptable aerial photography is honestly disappointing compared to Google Earth's impressive dataset. That said, we've already seen Apple deploy more 3D markets between iOS 6 beta 4 and the GM. The question for the future is not only how long it will take to get adequate coverage of the top 100 markets in the USA and abroad, but beyond that point what the re-visit schedule for this dataset will be.

That's not actually true. The only thing you're limited to buying from Apple is apps. Everything else can be bought elsewhere and read, or played. That's true for books, music, video of any kind, including Tv shows and movies, PDF's, etc.reuthermonkey1 - Thursday, September 20, 2012 - link
Assuming that Apple continues to allow those 3rd party apps to exist in their App Store...GSRennie - Wednesday, September 19, 2012 - link
I would rather buy Apps from the Apple Store and have some confidence that the products have been reviewed for functionality and are virus-free. I gave up on Windows years ago after adding up the time I was spending on malware control using the mix of products that you seemed to need to do a complete job. Add to that the item and money spent to get rid of viruses on various family computers (the kids weren't as cautious as I was). No doubt the Windows world is much more secure these days but I'm not going back. I run the occasional Windows program on Parallels on a laptop (with virus protection). Other than Apps for iPhones, iPads, iPods (all Apple devices), I don't see what outside content I'm blocked from getting by Apple. I can buy any software I can run on OSX and run any Windows software using Boot Camp and a Windows installation or Windows emulation options. As to the agency pricing model Apple and its partner publishers were pushing for textbooks, lets wait for a court ruling on whether that amounts to collusive price fixing. Apple wasn't setting the prices, and the publishers (with some considerable support from authors) were making the case they needed more revenue than derived from Amazon discounted sales to survive. I'm not trying to take sides on that issue until I hear more on the merits of both positions.Sufo - Thursday, September 20, 2012 - link
lol, instead of teaching your kids how to not bork a computer you simply ran away from the problem. If you can afford a mac, you could have afforded to buy them their own shitty laptop, which they could infect to the point of failure and then learn how to deal with the mess themselves... or not. Seems the typical mac user is a lazy parent as well as user!robinthakur - Thursday, September 20, 2012 - link
I think we are coming to the point where a computer should not be easily bork-able because it is essentially just an appliance which is reliable and easy to operate. This means things like OS drives and system files should be hidden to end users, but this would drive us technical types round the bend.The solution to most infections is simply to reinstall and restore/repoint data, and buying them a shitty laptop which may get infected constantly will simply waste time that they could otherqwise spend doing something more useful. Unless you teach your kids how to reinstall Windows also, that's a lot of wasted hours.
Also quite a bit of how you don't get infected is not necessarily teachable, which I realised recently trying to explain it to someone les technical. I was downloading a link from Zdnet and on the page there were loads of ads and download managers that looked like the download button but when you clicked them they tried to install some stupid software. The actual download link was fairly hidden. This and the dangers of pop ups/cookies/add-ins is not an easy subject to teach, its something we have learnewd and now take for granted.
If my Windows 7 or 8 pc (self-built I might add) kept getting infected with malware in a way which was difficult to defend against using the standard approaches, I would 100% look at moving to another infrastructure. Not everybody has the knowledge or time to deal with the problem as we would. It does not denote laziness, simply different priorities than you own. If a curated app store does get around the danger of malware from unsafe install locations, it's not surprising that its incredibly popular with regular users and is now being adapted by most of the companies out there. Even Android only trusts known safe download locations by default.

Ah the classic "blame the user" mindset instead of the fact that Microsoft Windows is a perilous platform to use when it comes to security.MykeM - Thursday, September 20, 2012 - link
The choice to shop where goods are sold cheaply is all good but it's not without downfall. But as someone pointed out your fury is bit misguided. With the exception of Apps, I can load onto my iPhone movies, books and songs that I got elsewhere. iTunes doesn't differentiate from items bought from its store or downloaded off Google Play- as long the format is compatible.The irony to finding cheaper price elsewhere is that media whether it's from Google Play, Amazon or iTunes, are priced equally. So there's hardly any truth in that argument.

Your last statement hasn't quite been my experience, at least on the content I purchase. I do don't do a lot of video purchases, but the few I have purchased have generally been cheaper on Amazon. I also routinely find music to be cheaper on Amazon, along with more specials to be had.Also, Apple may allow you to install media purchased from other sources, but it sure doesn't make such options a desired thing to do. Unsupported media formats require third party apps (for a price) along with the archaic way of transferring that content one-by-one, app by by, using iTunes, instead of allowing a true sync, as with supported content.
It is infinitely easier on Android to put the content you want on your device and consume it as you desire.
Again, not nitpicking, as your statements are accurate, but just point out that while Apple may "allow" something, they certainly don't make those "allowed" things something appealing to do.

I have a mac and an iphone and regularly buy content from Amazon - you're right, it is generally cheaper than itunes. It's also very easy to do, since Amazon supply a downloader for the mac which neatly places all your downloaded content directly in iTunes for you.Of course once the content's in itunes, it syncs with the iphone as easily as anything else does.

What a can of worms that is. People are surprisingly easily manipulated. The pen is built around them, and they don't notice or care. Thus the the term - iSheep. But it's our nature, I suppose; not inherent to just iFans. Look at our country and "our" government...
