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.

Courtney

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.

  with regards, Miro

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.

@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.

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.

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!

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

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.

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

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.

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.

I'd like to thank you again for all the feedback that you gave us. In the meantime, we have made all the remaining improvements that you suggested in our QA rules for detecting not connected highways and non-closed polygons. Thanks to your help, our future challenges will be even better.

Have a great week!

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

Invalid Turn Restriction
there already is a challenge for invalid turn restriction, so maybe you can contact with author, if you have same QA rule.

PS: If you made new challenge please let me know, so I can give you feedback. :)

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)

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!

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:
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.

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 t
