Polygon is Not Closed Challenge

Hello, Netherlands community

When we last wrote in August, it was to halt editing on a group of “quality checks” about which there were serious concerns. As promised, we have overhauled our approach and have made a number of improvements, including re-engineering our logic and re-writing our MapRoulette project and challenge descriptions and work instructions. Then, we restarted editing in a few areas, while performing an extra round of quality checks on 100% of our edits. The result is that we believe that our data and our challenges will now meet your standards.

And so, here is a MR challenge for “polygon is not closed.”


Please let us know if you have any concerns or feedback.

If you really want to improve the map, learn people how to map. I solved at least 20 of this challenge, all but one or two made by the same mapper.

And that mapper happen to live in Pune? :grinning:

Dunnow, he’s famous for his “Not so good mapping.” at DWG.
