Hi, we are TomTom - let's exchange ideas

Ik denk dat dat is omdat niemand echt ingaat op haar vraag maar er opeens een hele metadiscussie over TomTom ontstaat.

IMHO is het een vrij simpele fix die als een automatische edit gedaan kan worden. Doen. Maar verwacht wel dat je dit moet herhalen want dit is gewoon iets wat niet altijd goed getagd wordt.

As long as large(r) projects are shared within the community I don’t think it matters whether a party is commercial or not.
Great that TomTom decides to use Openstreetmap data and that they run an extra check on the quality of the data.

The two aforementioned projects don’t seem to hurt; I guess many people run similar fixes on for instance opening hours or phone numbers. So rewriting the kW into the correct form would be fine.
And I’m not particularly a Maproulette connoisseur but I know it gets a lot op people going.

I’d say: thanks for notifying and please let us know when there are new projects ahead!

Inderdaad, goed samengevat.
Ik sta hierachter.

Mijn reactie is mijn antwoord op haar vraag:

Ik beschouw Marjan als een van onze mappers. Als ze bepaalde dingen belangrijk vindt dan corrigeert ze die maar.
Uiteraard moet 22kw 22 kW zijn.

Voor geïnteresseerden:
De oprichter van OpenStreetMap heeft Oct 25, 2021 een blogpost op de TomTom website geschreven.

https://www.tomtom.com/blog/maps/the-battle-for-quality-maps/

Volgens mij heeft hij die blogpost geschreven uit hoofde van zijn huidige functie bij TomTom.

Het blijft inderdaad onze oprichter.

Hallo iedereen

Thank you for being so responsive. We really appreciate it.

Let me reply to these questions and comments:

Did you contact innovationteam@groups.tomtom.com? If yes, we’ll ask the team to get in touch with you.

The tool is brand new and still requires fine-tuning. That is why we really appreciate this valuable feedback. We will take it along as we further improve MapMetrics. Note that some of your concerns will already be addressed in a new release that’s coming out soon.

Regarding the false positives: Steve Coast’s team is working on removing these. He wrote about this in his most recent blog post (also mentioned in this thread by FriendlyGhost and Commodoortje).

Furthermore, we have new documentation about MapMetrics (in PDF format) that will answer some of your questions. Would you like to receive this?

Thank you for the Tasking Manager suggestion, it indeed seems useful.

We are not in that list because we do not offer commercial OSM software or services. We are however in the list of Organised Editing Teams.

Our editors are indeed paid.

Our company is mentioned in the project description.

Thanks for catching this. We’ve revised the challenge description so it’s more accurate.

We are happy to work on this if it’s helpful for the community. Our intent is to support the community’s interests (this particular challenge was prepared based on an idea described in this thread).

We willen hier graag aan werken als dat nuttig is voor jullie. Ons doel is om de noden van de community te ondersteunen (deze specifieke challenge werd aangemaakt op basis van een idee beschreven in deze discussie).

We’re glad to read this. It is indeed our aim to always share projects with the community upfront. We are currently working on detecting and reviewing issues in the map and will let you know if this results in any project plans. I can say already that we want to start working on road edits in the near future. We will keep you posted on this.

Once again, thank you all for the fruitful discussion.

Kind regards,
Marjan

I don’t agree. As far as I understand (but your information about what your goals are is still very limited!) TomTom is going to use OSM data to offer commercial services, hence my suggestion.

No, the mail adres on your page Organised Editing page.

Apparently we missed that message, I’m sorry about that. I will shoot you an email.

For your information: the new MapMetrics documentation I was talking about before is now available in the help section of MapMetrics.

Kind regards,
Marjan

At this time we are not using OSM data in any of our commercial services. If this changes, we will abide by the OSM community guidelines.

Eens doorgelezen maar ik begrijp dat gereden routes worden vergeleken met dezelfde route maar dan door Grasshopper berekend op basis van OSM data. Hoe meer de gereden routes afwijken van de route van Grasshopper hoe roder de tile wordt.

Eens in de data bij mij in de beurt gekeken maar een patroon kan ik er niet in vinden en al helemaal niet aanwijzingen waar de kaart verbeteringen nodig heeft. Wat dat betreft is Scheve_prio1_wegen_QGC kaart van @PeeWee32 heel veel meer bruikbaar, zie ook Waar ligt OSM highway het meeste scheef?

Thank you for sharing this. As @emvee pointed out and as listed in the documentation, GraphHopper was used to match the TomTom GPS traces to the road network. I can imagine some of the false positives stem from this process, especially given unorthodox movements some carriers of TomTom GPS logging devices may exhibit (e.g. movement against driving direction). A huge step would be if TomTom open sourced (part of) these anonymised GPS traces to the (research) community, such that we could run our own map matching algorithms and routers against the data and come up with even more valuable insights into the quality of the OSM road network (I would personally be very interested in this since I have done map matching experiments against the OSM road network in a research setting in the past). Perhaps it would even be possible to launch a Kaggle challenge with a subset of the TomTom GPS traces, divided into a test and train set, in order for the larger community outside TomTom to come up with the best possible way of using this data to find potential improvements in OSM. Would love to hear your thoughts on this!

Yes, make a Tomtom heatmap, just as we now have from Strava. For now Mapmetrics is unusable. But even then, here in the Netherlands we have much more options with different layers like BGT.

Hi, we will pass along that feedback to Steve C. and his team. Thank you!

MapMetrics has issues we’ve been working on. Mainly this is trainlines and water, as I said in the blog post about it. However it is a moving target, later months are better and we’ve been going back and rerunning prior months.

The existential issue is we can’t share the GPS data with you. In rural areas, it’s usually very obvious what’s wrong even without GPS. In denser areas it’s not so obvious (but can be with GPS). Sometimes it’s more hidden things like turn restrictions, or lots of people breaking the law (going down one way streets the wrong way for examples). But in any case, we’re usually pretty confident about “red” cells. If you have a particular case I can look at it, send a MM link…

Can’t → won’t. You own that data don’t you?

I had a look using OSM202107 and found on the A13 in Rotterdam a tile that is (dark) red according to the .pdf, the Median Count is larger than 50000:

Would be good if you can do a deep dive on this so it is clear why according to MapMetrics there are so many problems in this tile because I would be really surprised if you can find a real problem in the OSM data.
