Hi Martijn
"MapRoulette challenges have been designed specifically with the
armchair mapper in mind - no local knowledge should be required to fix
what MapRoulette asks you to fix"
There's the fundamental flaw in these types of sites. Of course you need
local knowledge.
Please provide "factual evidence" that it adds to OSM accuracy.
Please provide "factual evidence" that they are actual "fixes".
"MapRoulette gets help to some of the remote, forgotten places."
If they're that remote do they need "helping". Who's going to go there?
& again prove the edits in those locations are accurate & genuine.
OK. First random from your site:
http://maproulette.org/#t=IT_WaterCrossings/IT_RXING_11.333811432368_43.474069354879
How can anyone who doesn't live in area (I tried to copy/paste the
location but the info box disappeared!) possibly know which is correct?

Supposed missing soccer pitch in France. I mean, really?
I believe these sites add more inaccuracy than accuracy.

If you can provide factual evidence that MapRoulette (or its new
cousin MapBoxRoulette) are causing significant harm to OpenStreetMap
data, please let me know and - at least for MapRoulette - I can see
about appropriate measures. These could include providing better
instructions, or even taking down a particular challenge - as I have
done in the past.
My extensive experience preparing MapRoulette challenges, listening to
feedback from its users and looking at lots and lots of edits made by
MapRoulette users all point to the conclusion that this is a good way
to get a lot of eyes on particular problems, and get them fixed much,
much faster than would otherwise have been possible.
In a perfect world, we’d have local mappers everywhere. In the real
world, we can use all the help we can get. MapRoulette gets help to
some of the remote, forgotten places.

Subject: Re: [OSM-talk] Detrimental to the OSM database (was: Ways
needing smoothing back on track)
Hello All
Please include all replies to OM-Talk:
I was meaning to start a separate thread on this subject, but this
seems the appropriate time & place.
This website, along with http://osmlab.github.io/to-fix/ ( & maybe
others) are encouraging errors to be introduced to the OSM database.
For obvious reasons there's a discouragement of armchair mapping.
These sites take it another step into inaccuracy by asking you to
randomly correct a supposed error ( & I /really/ want to emphasise
'supposed') that the user can have no factual knowledge of whether
the error is true or not.
I live in the UK. How can I possibly know if there's genuinely a
"sharp angle" in Arizona or there's something less than 2 metres away
from another object that should be connected in Cambodia?
IMO these websites are detrimental to the OSM database & should be
rescinded.

Hi all - just wanted to let you know that the ‘Ways Needing
Smoothing’ MapRoulette challenge is finally being updated again. It
used to consist of mostly false positives for the past week, and
there still are some, but there should be some fun to be had there
still :)
http://maproulette.org/#t=waysneedingsmoothing/
It’s still U.S. only :( but we’re getting closer to being able to
doing it for other countries as well.
