TomTom Flames OpenStreetMap
An anonymous reader writes "TomTom Navigation has a recently launched article on what they call the 'negative aspects' of open data projects such as OpenStreetMap. As there are no hard facts and details to the studies they refer, the OSM community identified this release as classic 'Fear, Uncertainty and Doubt.'"
FTFA: "We harness the local knowledge of our 60 million satnav customers, who can make corrections through TomTom Map Share." So... open mapping projects are worse than their closed mapping product because their closed mapping product is collaboratively edited by the users... Nice argument.
I am a geek attorney, but not your geek attorney unless you've already retained me. This is not legal advice.
I would hope a self-driving cars use data from it's immediate surroundings to make decisions and just use a GPS as a navigational device that can be overridden by irl factors on the ground. It wouldn't even have to be sabotage that overrides a gps, just your avg Cop/Fireman blocking off a street temporarily.
IMO, people are bigger dangers. Especially in a situation like where faulty data will lead a GPS will tell them to turn the wrong way on a one way street and they don't really check. I have a friend that obeys the things blindly. I know the GPS is screwing up and using a route that may look good on paper but is utterly long irl compared to some shortcuts the locals know. But no, she never listens. The GPS says so and it must be followed. She's the type to veer into oncoming traffic on a one way street if, fate forbid, her GPS screw up majorly one day.
The motives are obvious, the critique is not very specific, everyone who is using OSM does realize their limitations, and anyone who is using mapping software and gets in trouble because they prioritize the mapping data over what they can see with their own eyes should not be on the road anyway.
Too bad for Tomtom, but they stopped to be relevant quite a few years ago.
The oddest part, to me, is that they kind of admit to the same issues in TFA:
Our map-makers are real experts, many having over 20 years' experience in the field. And we harness the local knowledge of our 60 million satnav customers, who can make corrections through TomTom Map Share.
Surely a disgruntled employee can be do a better job at keeping disgruntled users in check, than a community of volunteers...
Greetings and Salutations;
Well, I have been editing and contributing to OpenStreetMap for several years now, and, I have to say that while there is a point to the criticism, in general, I would disagree with their analysis. It is a bit too self-serving for my taste. I do not own a TomTom, but, have had a couple of Garmins, and, have used a TomTom unit before. The commercial maps have been no better than the Open Source maps, and in several cases have been far less accurate. There are a number of places here in East Tennessee where the commercial maps have the GPS insisting that I am driving through the fields on the side of the road.
One point where Open Street Map shines is that it has actual roads and trails in such places as National Parks and forests...where the commercial maps have nothing but blank green areas.

"Many drivers rely heavily on satellite navigation for precise directions, and mapping errors can be extremely dangerous, particularly in the case of one-way streets."
I see people using these commercial quality navigation units every day and still they take stupid actions like driving into a oneway street and making last second turns (right... left, NO RIGHT swerving all over the road) while spending more time looking at their statnav than on the road. Turn by turn navigation is dangerous by itself when used blindly no matter what maps are being used, they induce a near total lack of anticipation of traffic.
I wonder how they handle winter roads, like one can find in the northern part of Scandinavia.
This are routes that are open only in winter when the lakes are frozen, and provide very convenient routes and shortcuts. In summer however they are closed for obvious reasons.
Yeah, we really really really need a new moderator option, -1 marketdrone
They should worry more about Google maps/navigation. You get a smartphone with that on it, and suddenly a Tomtom doesn't seem like a good buy anymore. My mom has a Tomtom because she could practically get lost driving on a straight road, and it has worked well. However it has nothing on my smartphone with Google on it. Reason is that the smartphone can (and does) fetch map data in realtime. I don't have to remember to load maps for where I'm going and they'll be as up to date as Google has at the moment.
In terms of other features like plotting a route talking you through things and so on they both work fine.
That's their real threat. Anyone who has a newish Android smartphone already has this, and I have to presume it is available on all other platforms. It's free and it works well. You don't have to remember to bring anything with you, other than your phone which you probably already have. Heck even if you don't have the app you can download it in the field.
Between that and cars with built in nav systems, I can't see them having a market for much longer. Stand alone GPS units are going to be the kind of things that hikers use, if you are on a roadway your car, phone, or both will already have you covered.
The problem with open maps is that too many can edit them.
The problem with closed maps is that too few can edit them.

In addition to your very good point some of the commercial maps (used to?) deliberately add mistakes to their maps as a test that they can use to see if anyone is copying them.

The fact that Tomtom feels the need to bring up OSM says to me that OSM is now a credible competitive threat to them. The business model of selling maps for use on gps units is rapidly becoming obsolete, they can either try to fight it and become increasingly irrelevant, or adapt...
Incidentally, what i dislike about tomtom is that having bought the device, i needed a code to register my map, and this code was on a tiny sticker attached to the sleeve of a cd that came in the box... When my sdcard died, i replaced it, reloaded the software and map, only for it to refuse to work unless i entered the code. I still have the physical device, but have no idea where the code is (most likely lost) so am left with a relatively expensive device that i now cannot use via official channels.
Ofcourse, i simply found a crack online which allowed me to use the device i paid for without the tiny strip of paper containing an arbitrary code.

The one thing that sticks in my mind about Tomtom: when they got sued by Microsoft, the open source community rallied round. But did they ever bother making the minimal effort to distribute a Linux client, perhaps to show appreciation if nothing else? Appreciation not just for the support they got against Microsoft but for giving them a free platform to build their business on? No. Too much to ask, apparently. As far as I am concerned, Tomtom can fuck themselves.
Oh, and when I lost my Tomtom I did not replace it, I bought a Garmin.
When all you have is a hammer, every problem starts to look like a thumb.
I have been working with digital map data for on advanced driver assistance applications for a few years, and my experience is the following:
Some applications want lots of data. They don’t care if it is perfect or not, such as whether there is a zebra crossing, a traffic light, a stair, a path for mountain bike but not for road bike, etc. One example of this is navigation: it doesn’t matter if the turn has an error of 10 meter, if it is 10 or 25 degrees to the right, etc.
Other applications they are fine with less data, but this must be absolutely accurate to within a meter. Examples of this are active-safety applications, such as map-based adaptive front lighting, curve warning, etc.
Some other applications are in the middle. They are not very sensitive, but annoying if incorrect: example of this is speed limit warning.
The biggest map vendors collect hundreds of attributes at very high quality. This is true particularly for low-number functional classes (highways and motorways). They often meet the 5-m absolute and 1-m relative accuracy for geometry.
It is very difficult for OSM to meet this high quality, specially because you need a differential GPS (DGPS) to collect these. That said, map vendors invest most of their effort on large important roads, while rural or off-roads have from low to very poor quality.
Moreover, one thing is the quality at which data is collected, and another one is the map quality. Vendors tend to decimate (strip-out) geometry points on non important roads in order to reduce the size of the map.
So to sum up: if you are on a motorway or highway, OSM probably won’t match the quality of Navteq, Teleatlas or Google. If you are on a rural area, off-road, bike trail, etc., OSM will probably kick everyone’s butt. Plus it is usually more up-to-date.
TomTom tries to close this gap with their community content, which I find very dishonest from them. They save millions by using people’s data, but they don’t pass these savings back to the consumer.
Just out of interest, are the fjords and other bodies of water littered with the sunken remains of vehicles driven by those who forgot to switch their GPS to summer mode?
The reality is that the problem has never been with Ordnance Survey, but with the terms and conditions of Google Maps. It has absolutely nothing to do with derived data or our licensing terms but everything to do with Google claiming the right to use any data you display in Google Maps in any way it sees fit, even if it doesn’t belong to them.
Frustratingly, this is only a problem that exists with Google Maps. No such clause appears in the terms of any other mapping API, including Bing Maps and our own OS OpenSpace.
The problem with open maps is that too many can edit them.
The problem with closed maps is that too few can edit them.
TomToms problem with open maps is that they can't charge for them, and they compete with their product. This is just marketing BS AKA lies.
Navteq uses...
Navteq is the company that provides maps and mapping services. When you hear names like "tomtom", "garmin" and so on, these companies do not actually provide maps. They provide UI shells and minor map modifications but licence actual maps either from navteq or tele atlas (two biggest providers of mapping data in the world). Navteq and tele atlas in turn get their maps from their cartographers, one of whom you just mentioned.
In addition to your very good point some of the commercial maps (used to?) deliberately add mistakes to their maps as a test that they can use to see if anyone is copying them.

On the way to my former residence, all the mapping services I have ever use direct me to a bit of a shortcut, taking a small bridge over a local river instead of the bridge associated with the state highway.
Said bridge has been closed (condemed) since 1967.
I have attempted to bring this to the attention of multiple major map direction sites and gps companies, but despite 'accepting' my correction, the latest Tom-Tom unit (just for example) still gives the route over the closed bridge
