Is this Google Maps error actually a "trap" neighbourhood?

Posted by Derek Flack / October 28, 2010

google maps error torontoAfter last week's post about Google's recent conversion of Wellesley Street to Lourdes Lane, I started searching for other instances of errors on the Toronto version of their maps. And, as some commenters had predicted, I actually found quite a few. But, interestingly, hardly any that had yet to be corrected.

A few of these former errors included misplacement of subway stations (Downsview was apparently once placed in the TTC yards immediately north of Wilson Station), numerous misnamed streets and landmarks, and the incorrect labeling of certain neighbourhoods. While most of these have been cleaned up, at least one example of the last error still exists today.

Many who followed the Fuzzy Boundaries naming project last year noticed that what was then supposed to be a nameless neighbourhood had, in fact, already been given the designation "Silverthorn" by Google. But, in actuality, Silverthorn is a neighbourhood located north of what is now referred to as the Junction Triangle (which is also not quite properly placed on the map above).

What's a little odd about this particular mistake is how long it's been around. From what I can gather, the Silverthorn label has been out of place for at least a year and a half, and quite possibly much longer. All the other errors that I've read about from that long ago have already been corrected.

So, now enter the minor conspiracy theory.

Google maps error torontoMaybe this is a "trap" neighbourhood. The term "trap" in this context refers to the possibility that Google has misidentified the area intentionally so as to catch (or trap) potential copyright infringements from rival cartographers. More common with streets, the strategy does once in a while extend to towns, parks and buildings. So why not neighbourhoods?

It's long been suspected that TeleAtlas, the company who provided Google with mapping data prior to their split in 2009, incorporates "trap" information into their maps, and perhaps this is a remnant of that strategy that Google has left in place.

Given that mapmakers almost never comment on "trap" info, this little theory does, however, remain firmly in the sphere of speculation. But, along with the length of time the error has been left to stand, it's odd that the addition of the label "Junction Triangle" to the map (even if it's a little too far east) didn't precipitate the correction of the Silverthorn error.

So there's at least some reason to suspect that Google may be up to something. And, hey, it's certainly a hell of a lot sexier than thinking it's a simple mistake.

Huh. That's pretty interesting. Purposeful errors in maps as a kind of watermark.

I live in the Silverthorne neighbourhood, and as far as I could tell we all voted for Pantalone.

I know as fact that at least two manufacturers of print maps include trap streets in their publications to guard their copyrights. I suspected that whoever supplied Google does as well based on some of the interesting routes that come up when mapping a route from point a to point b

If you're in "Silverthorne" chances are you voted in polling station #1, #6, #7, or #8 of Ward 18. #6, #7 and #8 were won by Smitherman, with Ford in second. Polling station #1 was won by Ford by one vote, with Smitherman in second.

Hey guys! I know this is a little off-topic, but have you guys taken a look at what's been the latest buzz in Toronto?

There's this site called DealTicker.ca and they do massive deals on a daily basis that are up to 95% off!

Like today, they're featuring Oisi Oyster, an oyster & sushi shop in Eglinton & Mt. Pleasant area..... pretty cool!

Thanks.

It sure would f'ing help if they had the f'ing NAME OF THE WARD instead of just the number.

If anything, the label "Junction Triangle" is too far east. It's right on top of the eastern boundary.

This is kind of related, but a funny story regardless...

A few weeks ago my girlfriend and I decided to head to Chudleigh's Farm in Milton for a little apple picking. Anytime I'm going somewhere and don't know where it is, I turn to Google Maps. It has always been there for me, and never mislead me - until this time, that is.

A simple map search of "Chudleigh's Farm" will bring up the proper address, but the point on the map (and where the directions will send you) is incorrect. Check it out here: http://maps.google.ca/maps?hl=en&;q=chudleigh's+farm&um=1&ie=UTF-8&ei=ZbbJTKv4DKO0nAeR0YjyDw&sa=X&oi=mode_link&ct=mode&ved=0CAwQ_AU

Upon arriving at our Google Map destination, we quickly realized that we were in the wrong place (it takes you to a little subdivision in Milton - all houses). There was a man that lived on the street where Google was directing people to that was giving out proper directions. He claims that every fall he gets an estimated 100 or so lost drivers on his quiet street on Saturday and Sunday afternoons.

Apparently, several attempts have been made to contact Google (by both irate neighbourhood residents, and Chudleigh's Farm) and have them correct the error (which has apparently been an error for a few years now), and Google has done nothing about it.

Just an interesting story I thought I would share - possibly another "trap", similar to the mislabeling of Silverthorne?

openstreetmap.org allows you to correct mistakes like this! it's pretty cool... like the wikipedia of mapping.

Several other types of directories do the same thing.
An American directory of executives and other prominent
people deliberately add several fictitious names and
biographies to catch mass mailers trying to target
the well-to-do.

For the longest time, Rand McNally road atlases had
Kings and Queens streets in the Toronto enlargement map.

Copyright easter eggs are very common in maps, and you can find them even in paper maps (streets that don't exist, names changed, etc.). Some cartographers put them in for fun as easter eggs while others are ways for them to prove that people are copying their data. There have also been instances where this proof has been used to sue other companies for infringement. Here are some great examples courtesy OpenStreetMap: http://wiki.openstreetmap.org/wiki/Copyright_Easter_Eggs

Ward names are of little help since they follow the federal/provincial ridings, meaning every "name" is actually two city wards. Your voter card (if you still have it) has your ward and subdivision. Or, use this link http://www.toronto.ca/elections/candidates/voting-places.htm

Not Toronto but on the transit layer in Montreal it shows the Blue line ending one stop early before Showdon. I submitted it to Google several months ago but it is still there...

Not directly related, but another Google Maps error I noticed the other day: the Scarborough Centre RT station in mislabelled "Scarborough Center" (US spelling). Google is infringing on Canadian sovereignty!

And why for Ford's sake are the subway stations denoted with an [M] on Google's map of Toronto? I'd like to see the TTC emblem if possible, along with the actual path that the subway tracks take. What is this [M]? Metro? Ca n'existe pas ici.

Re Nick:

Google uses a 'M' to show subway stations in all cities, not just Toronto. And internationally "metro" is used in most places to refer to rapid transit, not just French places. Some English places that refer to subways as metros include Washington DC, Miami, and Newcastle.
