Re: [talk-au] Adding lane tags to major roads

[Martijn van Exel]

Thanks. Because you cannot edit the Overpass query for an existing challenge, I 
created a new one that has the LPI imagery as default backdrop.
The challenge lives here: https://maproulette.org/mr3/browse/challenges/3387 
 
It has 9800+ tasks. 
I deleted the old one.
Thanks for the suggestions!

 Could you filter out ways that have lanes:forward and lanes:backward?
 eg. https://maproulette.org/mr3/challenge/3375/task/6686753 
  which
 shouldn't need a redundant lanes tag as you can just add them up.

I just checked again, it looks like you haven't corrected this yet, so a
friendly reminder it would be nice to have this fixed.
I think it's also a good idea to include the NSW LPI Imagery as the
default background layer for this task. I just filed
https://github.com/osmlab/maproulette3/issues/572 in relation to this.
