[OSM-talk] Responding to vandalism
Hi all, Last saturday, Central park in New York City was vandalized by a new OSM user `Meowthreetimes` in all the map edits: - 46756622 introduced a fictional lake inside Central park https://www.openstreetmap.org/changeset/46756622 - 46756461 renamed Central park in https://www.openstreetmap.org/way/427818536/history - 46756506 introduced a fictional lake near Fort worth Dallas http://www.openstreetmap.org/way/479837732/history It took 2 days for the edits to be noticed and reverted on one of the most popular locations in the world. This was possibly preventable with a more active mapping community, but a previous incident [1] highlights how simple cases like dragged ways can stay around the map for months under the eyes of local mappers. The current strategy of leaving changeset comments to users to prevent bad edits does not scale, especially if the mappers do not read messages like Maps.me editors [2], or if there are no expert mappers in the area who are knowledgeable in reporting and reverting changes. Thinking out loud on how we could better improve the current process to act on bad edits: - DWG currently acts promptly on incidents reported via email, but we need a more accessible mechanism that allows new users to report such incidents directly from the website or editors. The email details and existence of DWG, is only available currently in the wiki [3] - Auto-blocking known vandals to prevent repeated attacks [4] - An organised repository to report and learn from previous attacks. There seems to have been an effort to do this many years ago on the wiki [5] - More visibility, awareness of QA tools and history tab on the OSM homepage. Most of the really powerful QA tools like osmhv and osmose are only known to advanced users. It would be great to hear more approaches that could protect the map against common mistakes and intentional attacks. Much of the world lacks an active mapping community, so it is up to a small set of power mappers to catch and revert most of the bad edits [6]. Building better support systems to respond to bad edits could help more experienced mappers focus on community building activities.

Re: [Talk-ca] Mapping exit numbers and destinations in Canada
Hi everyone, Thank you Harald, James and Kevin for your replies. We currently follow the proposed mapping methods in the Wiki [1] James had mentioned. We have observed that there are name tags given for junction nodes[2] in which destinations were given. Is this a previously agreed tagging method to render destinations on nodes or is there any particular reason the name tags were given to the junction nodes? Is it okay if we delete these name tags on junction nodes now that we are giving destination, destination:street tags to the exit ways?

[Talk-ca] Mapping exit numbers and destinations in Canada
Hello everyone! Turn restriction sprint was met with an amazing response! We loved working with you all on adding turn-restrictions in Canada. We appreciate the timely help and suggestions we got which helped us add correct restrictions and to also maintain the quality of data we were adding on to OpenStreetMap. We hope that this support will continue further, as we are embarking on mapping exit numbers and destinations in the same 5 cities of Canada. We have made an easier workflow [1] with tasking manager [2] for adding exit and destinations. We would like your assistance, participation and continued involvement in the project. We have captured the details of this task here [3]. After a preliminary look into the already mapped exit numbers and destinations, we have these observations: - We noticed that `destination` (places, cities) and `destination:ref` (highways) tags are being added to the nodes of exits as `name` tags. - Few exit nodes have destinations given in the `ref` tag. - The `destination:street` (towards streets, avenues, boulevard, rue) tags were not being used. To begin with, we have one question: Destinations given in the name tag of nodes is not usual protocol for adding these tags. We want to make sure whether it is valid or if we could change these tags to the `destination` based tags accordingly. For more details, here's the complete breakdown [4]. To reach out to more audience, we have captured this in a OSM diary post [5]. We would like to hear from the community about the agreed method of mapping exit numbers and destinations to take this forward. 1. https://gist.github.com/manoharuss/3a1b4f640aaf2c052365fcb1ddb09beb 2. http://cfn-tasking-manager-staging-vpc-387856624.us-east-1.elb.amazonaws.com/project/20 3. https://github.com/mapbox/mapping/issues/220 4. https://gist.github.com/poornibadrinath/9333f1489732c32c3ffadd58e3068b7e 5. https://www.openstreetmap.org/user/poornibadrinath/diary/39246 Thank you!

[Talk-ca] Canada road network 2015 open data -StatCan
Hey there, I have across this 2015 Canada road networks open data set from StatCan, I posted a quick diary post on OSM[1]. This seems like a great dataset to evaluate the quality of data and coverage of roads in Canada. Would love to hear from the Canadian OSM community of any previous work using this dataset that can be taken forward. 1. http://www.openstreetmap.org/user/manoharuss/diary/39203 Best, Manohar ___ Talk-ca mailing list Talk-ca@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-ca
[Talk-ca] Mapping tun restrictions in Canada
Hey there, Thank you for your reply Andrew MacKinnon. Status update : We mapped 110 turn restrictions in the last 2 days in Canada. We have faced an issue we would love some feedback on ( https://github.com/mapbox/mapping/issues/213#issuecomment-235214856).

[Talk-ca] Mapping turn restrictions in Canada
Hey there, Today we mapped 76 turn restrictions in Canada. You can follow the project tracker here(https://github.com/mapbox/mapping/issues/213) and get involved. We have across signage with text we are not so sure about, it would great if canadian mappers clarify us on these. 1( https://d1cuyjsrcm0gby.cloudfront.net/4ZA3OT0nHoDQ7F7JILG-pg/thumb-2048.jpg), 2( https://d1cuyjsrcm0gby.cloudfront.net/IYi6WjwOQDnPW1HTTGyh8A/thumb-2048.jpg ).
