Mappy horror picture show in South Sudan
Posted by UNGSC-DTLM-Ale_Zena on 26 September 2024 in English.Working mainly in Africa it’s not rare to come across to crowdsourced powered mapped areas. I still repair, from time to time, the disaster done in 2022 in Mogadishu
Today, near Bor https://www.openstreetmap.org/#map=17/6.178444/31.578194 , another masterpiece: a lot of triangular (one 2600 sqm trapezoidal) buildings, and 3 tourism=camp_site
Who does need this rubbish? How good the validator to the related HOT task worked?

HOT frequently provides a disservice to the OSM community. This mess is the responsibility of whoever organises these mapathons and fails to educate the newbies and ignores the need for validation and iterative improvement of the map.

To be clear, this wasn’t created today. From looking at an example edit https://www.openstreetmap.org/way/1003640656 , the changeset was 3 years ago: https://www.openstreetmap.org/changeset/114107972 . The mapper made 19 edits in 2021, and contributed no further to OSM. The HOT project is https://tasks.hotosm.org/projects/11218 and the organiser of that project is https://www.openstreetmap.org/user/ngumenawesamson . They are still active in OSM, and I have commented on a recent changeset of theirs suggesting that they may wish to read this diary entry.
What we don’t know is who ran the mapathon (or whatever) that prompted the changeset that created the triangular buildings (or if there even was anyone supervising it). We do however know two things:
that the person who created the HOT task hasn’t bothered to look at the quality of the work done in the name of that HOT task, or has looked and hasn’t bothered to tidy it up.
that there aren’t enough people looking at “changesets by new users” in this part of the world. The problem changeset here even had
review_requested=yes(automatically set by iD, I guess), and no-one has noticed it for 3 years.In this particular example it’s probably too late to contact the original mapper. It’s not too late to tidy up the problem data (now there’s a diary entry pointing at it, I’m sure someone will de-trangularise the buildings). However, what would be really useful would be to have a look for much more recent
review_requested=yeschanges, and offer helpful advice (after an initial “hello and welcome” message).Best Regards,
Andy

Hello Andy, first of all, as always is due, a big big thank you for you work behind the curtains.
Yes, I know is a 2021 edit. I left for a few days the area untouched so who read my message could see it. In a couple of days I’ll review the area.
Best Regards, Alessandro
