Hi all,
Per Matthew Darwin’s request on Twitter, my team prepared a MapRoulette
challenge for ‘highway class flip-flops’. What does this mean? Consecutive ways
that have a suspicious change from one highway= value to another and then back
to the former. This happens sometimes when mappers change the highway= value
for some way but miss a bridge somewhere. An example is
https://www.openstreetmap.org/way/53514358#map=19/51.23309/-116.65373
<https://www.openstreetmap.org/way/53514358#map=19/51.23309/-116.65373> where
the bridge is marked as residential but the two adjoining ways are marked as
unclassified.
You can find the challenge at https://maproulette.org/mr3/challenge/3588
<https://maproulette.org/mr3/challenge/3588> and your feedback is very
welcome.There are ~300 tasks.
If you have other ideas for challenges to clean up / review existing data let
me know and we can discuss.
Martijn
