Starting to add roads and other features in Somalia, around Baidoa (Baydhabo بيدوا), I often come across with long ways that have “attribution: Mart Roumen; FAO-SWALIM; Madmappers-SOM-2008-01’”. Most of them are not more visible through many satellite imageries, sometimes cross water or residential areas regardless of any feature on the ground.
I know Somalia and other territories can change very quickly but it looked me strange that so many areas changed dramatically. So, when I have no evidence of them I delete them.

(as an example to find who created something like this) I searched taginfo for part of that string and then clicked through to an overpass turbo query on part of Somalia.
As an example, that found this way which was added in this changeset. If you comment there an email will go to the user, but as they haven’t been active in 11 months they may not see your message.
These roads were added 7 years ago, so I suspect that there isn’t a problem with deleting ones that don’t exist in any currently available imagery and don’t have GPS traces backing up their location.

Yes I think so, I’ve written that just to let know why I’ve deleted so many road.

Hi I found this diary through a google search…I have come across these roads as well. I noticed that a lot of them don’t align to any of the default imagery (Bing, Digital Globe or ESRI). I will go ahead and delete them or correct them as well!

Delete them? Why you should delete a (maybe) disaligned geometries? If you are pretty sure are misaligned you’re welcome to correct them, but you shouldn’t delete.

To clarify I am not deleting the ones that are slightly misaligned ones…just deleting ones that are very obviously wrong. For example if they are not near roads in any of the available imagery and cut through whole neighborhoods.
