Southern Asia QC Project

[Courtney Williamson]

Hello everyone,

I'm Courtney from TomTom. Would you prefer that I translate this message to Slovak? I would welcome a recommendation for a reliable online translator if so.

We used public instances of OSM QC tools such as Atlas and Osmose in addition to internal validation to detect potential map data issues in Southern Europe, including Slovakia.

The quality checks in the challenges for this project are mainly focused on potential issues that would impact the road network and tags that affect automotive navigation applications. Note that additional information is available in each challenge description. Furthermore, some challenges will occasionally show only a few or no tasks. We will update these challenges as new data becomes available.

We will begin working on these tasks in a few weeks.

Here is the project (for multiple countries in Southern Europe including Slovakia):

https://maproulette.org/browse/projects/46945

Let me know if you have any questions or suggestions. We are also interested to learn if there is any other topic we can support you with.

Hello,

I completed almost every available task located in Slovakia (some are completed but system has not delete them [around 18 tasks], some needs visit [around 3 tasks]). When some new ones will appear I will try my best to implement them.

If you have some subscription link, where I can subscribe, if you will add new tasks I will appreciate it.

@Courtney: Hi Courtney, I have translated your message to Slovak with google translate which does a good job in English->Slovak:

Prikladám preklad správy od Courtney, pre tých čo nehovoria po anglicky:

-----------------------

Ahojte všetci,

Som Courtney z TomTom. Boli by ste radšej, keby som túto správu preložil do slovenčiny? Ak áno, uvítam odporúčanie spoľahlivého online prekladača.

Okrem internej validácie sme použili verejné inštancie nástrojov OSM QC, ako sú Atlas a Osmose, aby sme odhalili potenciálne problémy s mapovými údajmi v južnej Európe vrátane Slovenska.

Kontroly kvality vo výzvach pre tento projekt sa zameriavajú najmä na potenciálne problémy, ktoré by mohli ovplyvniť cestnú sieť a značky, ktoré ovplyvňujú automobilové navigačné aplikácie. Všimnite si, že v popise každej výzvy sú k dispozícii ďalšie informácie. Okrem toho niektoré výzvy občas ukážu len niekoľko alebo žiadne úlohy. Tieto výzvy budeme aktualizovať, keď budú k dispozícii nové údaje.

Na týchto úlohách začneme pracovať o niekoľko týždňov.

Tu je projekt (pre viaceré krajiny južnej Európy vrátane Slovenska):

https://maproulette.org/browse/projects/46945

Ak máte nejaké otázky alebo návrhy, dajte nám vedieť. Máme tiež záujem dozvedieť sa, či existuje nejaká iná téma, s ktorou vás môžeme podporiť.

Hi

I have looked on one local task https://maproulette.org/challenge/23712/task/121084426 and it was confusing. It says: "This check identifies a way connected between two other ways whose name tag is the same."

I saw that mentioned way has a name, and it was between ways with different names, so it does not match the description. Ways were not modified in last months.

I saw that this way did not have "lanes" marked and it was between ways with marked "lanes". Maybe your task description was incorrect? I have added the lanes and marked task as closed.

highway=construction;

highway=proposed;

removed:highway=*;

Thanks everyone for your input!

@Filip009: Thank you so much for contributing to the challenge! I'm not sure if it's possible to subscribe to a MapRoulette challenge. I will check with my team. If we have any new projects, we will definitely post them in this group.
Thank you as well for your recommendations regarding the Not connected highway challenge. I will also take this up with the team.

@Miro: Thanks for the translation and for your feedback on the task description. I understand your confusion. The full description is in the challenge description:

"Identify way connected between two ways whose name tag is the same. Flag the way if the way has a name tag different from the name tag of the ways connected to it or if there is no name tag."

Does this answer your question?
To avoid confusion in the future, we will look into extending the task descriptions.

Hi Courtney

it does not answer my question at all; as I mentioned - the way in the task was "between ways with different names" so it does not match the description - connected ways did not have the same name.

Please make them not scanned.

[Courtney Williamson]

@Filip009 and Miro

Thanks for your additional input about the 'Road Name Gap' challenge. We investigated this case, and indeed it looks like there are some issues causing false positives. We have now hidden these specific challenges to prevent users from contributing to them.

@Filip009

Secondly, we took a look at the 'Polygon is not closed' issue with the benches. Thank you for pointing this out as well–these cases should not be logged in the challenge. We have taken this up with our engineers and hope to have this fixed soon.

In the meantime, our team was also able to take a look at your comments about the 'Not Connected Highway' challenge. Indeed, highway=construction and highway=proposed should not be checked, thank you for this suggestion! The QA rule will be improved accordingly, and we will let you know when the challenge is updated. Removed:highway=* was never a part of this QA rule, so no violations should be logged for this case.

I also checked if there's a way to subscribe to a MapRoulette challenge, but unfortunately there's no built-in functionality for that. A bit of code would need to be written against the MapRoulette API.

Polygon is not closed

I think that it is not an issue when members of relations are not sorted properly. I have started some tasks and always multipolygon was closed, but members were not sorted properly.

[Courtney Williamson]

Thanks for your additional comment, Filip. I also passed this along to my team.
They are working with your feedback, and I will come back with an update next week.

Thanks again for sharing these comments, we really appreciate it.

Courtney

[Courtney Williamson]

Hi Filip009,

I just wanted to give you an update on our progress in implementing your comments.

The bench issue with the Polygon is not closed QA rule was actually resolved earlier last year. The tasks created in MapRoulette before that time will be carefully reviewed by our editors. The violations logged after that should not include benches.

Regarding your latest comment about Polygon is not closed issues in case the members of relations are not sorted properly: we actually do not check if members are sorted or not. If you encounter such a case again, could you please share the task ID with me? Then we will review it.

For the Not connected highway challenge: we are working on adapting the QA rule so highway=construction and highway=proposed are not logged.

Thank you again for all your valuable input!

[Filip C]

Polygon is not closed

I do not see any issue with these multipolygons.
https://maproulette.org/challenge/23703/task/121397293

https://maproulette.org/challenge/23703/task/121397291

https://maproulette.org/challenge/23703/task/121369477
https://maproulette.org/challenge/23703/task/121369478

These multipolygons are closed. They have good tags. Each way is part of that relation. Maybe it has scanned it in the past? I thinked that it is caused by not properly sorted relation, but now I do not think that, because these were sorted properly and you have had still find some issue.

Please, if it is possible, just show me the way where is that intersection. In small multipolygons it's easy to find them, but in bigger ones like this one, I can not find it :(

Hi Filip009,

Thank you for these additional comments.
These are also false positives, which were caused by issues with the QA rules that we solved last year as well. Again, our editors will carefully review these tasks. Projects created in the future will not contain such cases.

Hello, I have idea of new challenge: Overlapping highways ?

Hi Filip, thank you for your latest suggestion! I've passed it along to my team.

Marjan (Courtney's co-worker)

[Filip C]

Not connected highway

Please do not check highway=rest_area

And to my idea of overlapping highway challenge I mean 2 cases:

1) when 2 ways with highway=* (exept cases i have reported previously for Not connected highway challenge) are crossing each other but are not connected and

     1.a) are without layer

     1.b) layer on first highway equals layer on second highway

     #2.a) tag bridge=* is without layer

               tag layer>0 is without bridge=*

     #2.b) tag tunnel=* is without layer

               tag layer<0 is without tunnel=*

2) when there are 2 highways on each other

#this part maybe for next challenge?

there are a lot of false positives (or just I'm not enough skilled to find them?)

Is it a problem, when leisure=track is not polygon?

On wikipedia is, that it could be just a simple way too https://wiki.openstreetmap.org/wiki/Tag:leisure=track

[TomTom]

Hi Filip,

Thank you for your additional comments.

Regarding the 'leisure=track' cases in the 'Polygon is not closed' challenge--a violation is logged if the following conditions are met:

• leisure=track AND area=yes, OR
• leisure=track AND type=multipolygon.

Did you encounter any cases not meeting these criteria?

For the 'Not connected highway' challenge, our team will look into fixing the QA rule so highway=rest_area is not logged in future projects. Thanks for this advice.

In general, I can assure you that our expert editors carefully review each task so they can mark false positives as such.

Thank you also for the detailed input about your overlapping highway challenge idea. It is an interesting suggestion and we will keep it in mind.

Marjan

[Filip C]

I did not checked each leisure=track, but I remember on these I opened were tags as area=no. And every track were just a siple way, not an area. Mostly there were 2 and more ways nearby each other.

Hello,

again on this task https://maproulette.org/challenge/23704/task/130948899 I do not see any issue. If there is some please let me know.

1) role of the way is correct

2)I do not see a line crossing anywhere

Hi Filip,

I believe, that the issue is here:

How to find it:

1) download the Way from the Task.

2) select the relation it belongs to and download it with all its members

3) select all downloaded data (shortcut CTRL+A) and choose Validate.

I leave the correction up to you :)

Tag area=yes on object without feature type

area=yes AND piste:difficulty  is not an issue. See https://wiki.openstreetmap.org/wiki/Key%3Apiste%3Atype#The_piste_as_area

We haven't added new challenges since I started this thread, but I will let you know if we do!

Then I'm sorry. Bur first time you have send project link I have just saw 4 challenges. Just randomly I looked into it, few days ago, and I saw 2 more challenges. So I thinked that you have made 2 new challenges. How many challenges are there currently in Slovakia? 6?

So I have just edited the link and with changing the id I have found a new challenges which I have never saw before :D. Maybe it's caused by somebody marking most of tasks as hard. They are 12 :O

Slovakia | Polygon is not closed (23703)

Slovakia | Polygon has self intersection (23704)

Slovakia | Not connected highway (23705)

Slovakia | Tag area=yes on object without feature type (23706)

Slovakia | Missing tag or role on feature (23707)

Slovakia | This multipolygon is a simple polygon (23708)

Slovakia | Impossible angle in a highway (23709)

Slovakia | Spiky buildings (23710)
Slovakia | Invalid Turn Restriction (23711)

Slovakia | Road Name Gap (23712)

Slovakia | Invalid Lane Tag (23713)

Slovakia | Invalid Mini Roundabout (23714)

[TomTom]

Hi Filip,

Indeed, we released 12 challenges for Slovakia back in December. I could not find a reason why you would not have been able to see all of them–perhaps it was a glitch in MapRoulette.

Right now, if you go to the MapRoulette project link, you should only see two challenges for Slovakia (Spiky buildings and Polygon has self intersection). Is this the case for you? The others are not shown because 1) all tasks have been completed, and/or 2) the challenge was automatically archived by MapRoulette because the tasks were older than 6 months.

If you want to see the full list of challenges for Slovakia (regardless of whether they were completed/archived or not), you can take a look at the "Challenges" section of the Slovakia project page that we recently created in GitHub. Note that this list does not contain two of the challenges (Road Name Gap and Missing tag or role on a feature), because we decided to no longer release these challenges. All tasks in these two challenges were completed, and no new tasks will be added in the future.

I hope this gives you the information you were looking for. Don't hesitate to let me know if you have any more questions!

Marjan

[Filip C]

Thanks for explanation. :)

Yes, I see only 2 challenges. 1) But Maproulette is also tagging challenges with tasks marked as "Too hard/Can't see" as completed, which is not good, I think. In my opinion there is a big difference between too hard and can't see. If is something too hard for somebody, somebody else can fix it. If it is not visible from available sources, then could challenge be marked as completed. But that's improvement for MapRoulette.

And please edit "Sources for editing" on github to:

Ortofotomozaika SR/Orthophoto mosaic Slovakia

DMR 5.0 SR/DMR5: hillshade BW SR

We mostly map based on these sources. :)

Hi Filip,

Your point about tasks marked as "Too hard"/"Can't see" is a valid one. We're aware of this issue in MapRoulette and are looking into how to deal with this.

And thank you for sharing those sources! I've added them to the GitHub page and I've alerted our editors about this.

Marjan

[Filip C]

Hello, can you see who has marked task as "Too hard"? Because some tasks are not too Hard and I think somebody is just skipping them to earn points, or I do not know why. In challenge "Not connected highway".

In my own challengeI can't find this possibility, so I think you would not find it too.

Filip

[TomTom]

Hi Filip,

In admin view, we can see that some of our editors have marked tasks as "Too hard" in the "Not connected highway" challenge. We checked and the reason for this is that based on the imagery available, they were not able to make the edits with the appropriate level of confidence. They will only make changes that they can verify as correct based on the sources available. If you have an example of a task marked as "Too hard" that you believe should not have been marked as such, feel free to share.

Marjan

[Filip C]

I'm marking tasks, which cannot be seen on Ortophotomosaic or DMR 5.0 as "Not an issue" because, they cannot be verified from the computer. They need to be resurveyed so they are not real issues, they just wait for somebody to check them in reality.

https://maproulette.org/challenge/23705/task/132572290 In this one you can see from Ortophotomosai, that on the north it is coonecting to nearby track.

https://maproulette.org/challenge/23705/task/132572291 This one is really hard, but I think there is road on the south or just mark this task as Not an issue an somebody sometime will resurvey it.

https://maproulette.org/challenge/23705/task/132572292 This one have on the southest point meadow with track pointing  to the forest, so maybe connect it to that point and run it accross meadow.

https://maproulette.org/challenge/23705/task/132574613 In this case some new mapper has made a mistake to tag way as highway=footway not highway=path in the forest. And from DMR is visible, that track need to be connected on west to the nearby track, where is now footway.

[TomTom]

Hi Filip,

"Not an issue" is actually meant to be used for cases where you can reliably verify that the issue is not actually an issue (in other words, a false positive). Marking these cases as "Not an issue" makes it clear that there's no need to take another look at them in the future.
If it's not possible to verify a certain issue (for instance because the imagery sources available don't provide the necessary visual information), and therefore there's still a possibility that it's an actual issue, the task should be marked as "Too hard". This indicates that it's useful to revisit this case.

Thank you for your pointers for solving those particular tasks. I have passed this information along to our editors so they can check if they can fix certain tasks based on your suggestions.

Marjan

[Filip C]

They really needs to split "Too hard" and "Can't see".

Hi Filip,

It’s been a while since we talked, I hope you are doing well!

Thank you for all the tasks you’ve already solved in our TomTom challenges, we really appreciate your help!

I was looking at the "overlapping highway" challenge suggestion you shared last year:

And to my idea of overlapping highway challenge I mean 2 cases:

1) when 2 ways with highway=* (exept cases i have reported previously for Not connected highway challenge) are crossing each other but are not connected and

     1.a) are without layer

     1.b) layer on first highway equals layer on second highway

     #2.a) tag bridge=* is without layer

               tag layer>0 is without bridge=*

     #2.b) tag tunnel=* is without layer

               tag layer<0 is without tunnel=*

2) when there are 2 highways on each other

In the meantime we have actually created a process that identifies, among others, occurrences of scenarios 1a and 2. We ran it on Slovakia, but only found 5 issues. It’s probably not worth creating a whole challenge for these cases, but if you’re interested we could create map notes?

Related to scenarios 2a and 2b, we have a process that identifies issues in bridge and tunnel tagging. I will let my team run it on Slovakia to see what we find.

If you have any other suggestions or comments, I’m happy to hear them.

Have a great weekend!

               tag layer>0 is without bridge=*

     #2.b) tag tunnel=* is without layer

               tag layer<0 is without tunnel=*

2) when there are 2 highways on each other

In the meantime we have actually created a process that identifies, among others, occurrences of scenarios 1a and 2. We ran it on Slovakia, but only found 5 issues. It’s probably not worth creating a whole challenge for these cases, but if you’re interested we could create map notes?

Yes, I will at least fix these 5 :)

Related to scenarios 2a and 2b, we have a process that identifies issues in bridge and tunnel tagging. I will let my team run it on Slovakia to see what we find.

That would be great. Can you please send me link then?

Thanks. :)

Thanks Filip! I will share the links for any notes or challenge we create.

Hi everyone,

I just wanted to say that I started a new topic to talk about TomTom's activities in Slovakia: https://groups.google.com/g/osm_sk/c/FYZ7bTONH90

Have a nice day!
