3D 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.

    gotta disagree with the author on the tablet web browsing.
    The convenience of web browsing on a tablet is one factor, instant access, easy finger gestures, it should be enhanced in the future so that we do away with the uneccessarry luggage like a keyboard and mouse. Even cutting and pasting have improved, i'm not sure what the author is talking about copying multiple links, mass email etc, the point of Ipad internet browsing is purely entertainment and should be improved upon. IOS does an amazing job on memory management, especially these websites that invades your browser with crazy advertising pop ups. Sinces Android foundation is from Java it might as well be the devil's advocate in crashing and freezing your device.

    What if you are away from your tablet and are browsing the web, but then you have to stop or you want to save something for later. Then later you want to browse on your tablet instead, and you'd like to pick up where you left off or go back to what you'd saved. It seems like that's the point of the new Reading List syncing feature. How else would you do it besides emailing the links?

    Some typing is still required when using the web, right? Typing on a touchscreen has improved a lot but is still like a bit like using a keyboard with gloves on. I don't know what my WPM is on a tablet but it must be must be at least cut by 70% or something. I have still occasionally switched to using my desktop when I need to figure something out on the web since it is just much faster. Also, depending on what I'm doing, I may need to look at several web pages, my own notes, or something else why writing an email or a writing something. This is more than just web browsing and although a tablet screen is bigger than a phone and closer to a desktop/laptop, the functionality just isn't there for doing something like that with a tablet. If you're really just "browsing" then a tablet is comfortable for that.

    Only been using nav for 1 day, but the one annoyance that could likely drive me (no pun intended) back to Waze or Navigon is that when the voice guidance comes on, it talks on top of music and podcasts. Other navigation applications will stop playback from other applications, then resume when voice guidance is done.

    it's frustrating when I'm listening to Brian and Anand, then having to rewind every time new voice guidance comes on in then middle of one of Brian's tangents!

    I would like this feature when I'm listening to music, but not when I'm listening to talking heads.

    Just upgraded my iphone 4 to iOS6. The maps app is nowhere close to what google offers so far. I knew there would be issues during the initial release due sheer volume I suppose.

    Even without turn by turn directions or 3D flyover, the larger direction signs that show up are pretty good for navigation.

    The standard maps are very ill configured and barely show any info. I'd have thought that with Tom Tom being a GPS company would have a rather comprehensive database already. My scaling is wrong and many areas are missing. No streetview means by default means I have to wait for google to release their app.

    I think I was very impressed with the updates going from iOS4 to iOS5. Going from 5 to 6 however hasn't impressed overall that much yet.

    The autobrightness is weird and isn't the same as before for some reason. I had issues with home sharing when it worked flawlessly before, infact was a huge improvement between updates up till now.

    I do love the options now present when getting a call.

    I'm dissapointed that this article completely glosses over the fact that the maps themselves look like absolute garbage. The way the roads are rendered and the colors used is god-awful compared to google maps, UI being Apple's main selling point. Its hard to tell road types apart close up and hard to read the map in general because of the way its rendered, with thin roads and all. I find it to be a piss-poor implementation and am dissapointed at the soft-white tinted glasses that appeared to be the filter this article went through.

    I'm comparing what I'm seeing on iOS Map and Google Map- limiting to my milieu since I'm familiar with it- but what I'm seeing is quite comparable.

    There are a few things on the iOS6 map that seems incomplete. For example, rail track- yes it's much, much narrower than the street but missing the required lines that cut across the track.

    But the street itself- the iOS6 version seems better at replicating and differentiating the various width of the main thoroughfares and side-streets. When toggling between the layers of Standard and the Satellite maps, I can clearly see that Google map does a poorer job- it seems to replicate the traffic flow rather than the road itself (resulting in curvier turns when it's actually right-angled). Expectedly, it does a better job at marking various businesses around the neighbourhood. One area where the iOS version will improve over time.

    Colour choice and preference are completely subjective but again except for a few choices of colours, both maps seems to me more similar than they're different (Skeuomorphism aside).

    I disagree completely I'm afraid. I was quite worried updating to iOS 6 that the maps would be awful as many early previews of the dev version said, but on my device it runs really fast, we have brilliant 3D flyovers and the maps are accurate and scale nicely. I especially like the rotation and elevation two finger controls like on Android Google maps. Since using G Maps on Android I always though the iOS implementation was a poor cousin, so I think it is good that Apple have finally come up with something comparable and slick which will hopefully grow swiftly. Navigation is much less confusing and busy than the Android version from what I have seen so far. The Siri integration is the icing on the cake.

    I do miss street view, buit rarely used the public transport navigation bit as Transport for London has a superior service available. At least now when Google release a mapping app it can be as Google want it to be and it will be up to the user whether they want Google tracking their every move and making money off of their browsing/map use.

    I really enjoy reading the article. It is very informative. Thank you.

    1. There are 2 authors listed for this piece. I just wanted to know who is the "I," "me," "mine," ... in this. That is very confusing.

    2. "at present [Google] literally is the 9000 pound gorilla for maps." Literally? Literally? That is like a friend of mine said to me "I literally haven't seen you for a million years."
  • ciparis - Sunday, September 23, 2012 - link

    Well, considering:

    1) they do weigh 9000 pounds (or more)
    2) at least a few of them strongly resemble a gorilla, so who can say that they aren't?

    I don't see the problem. Plus, your friend might just be a time traveller.
