Re: [Talk-ca] New MapRoulette challenge to address highway class flip-flops

Harald — you can go into your User profile and change the Default Editor 
setting to ‘Edit just features in JOSM’. This will load just the ‘abnormal’ 
highway. You can then load more data around if if needed. If you don’t want to 
change the setting globally you can use keyboard shortcut ‘y’ to trigger this 
type of loading in JOSM on a task by task basis.

Hope this helps, 
Martijn

Hi Martijn:
I just tried the challenge, and all of the first four tasks that came up
produce an "area too big" error in JOSM (long highways in very rural
areas). Is there any way to fix this? Or maybe warn people to not use JOSM
for this challenge?
 Harald.

Just as an addendum, you may find false positives like this one 
https://maproulette.org/mr3/challenge/3588/task/11055949 
 where a service road 
connects to residential roads in a perfectly valid way. You should mark these 
as ’not an issue’ in MapRoulette.

[Talk-ca] New MapRoulette challenge to address highway class flip-flops

[Martijn van Exel]

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 
 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 
 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.
