<div>Hi Martijn<br>
<br>
"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"<br>
<br>
There's the fundamental flaw in these types of sites. Of course
you need local knowledge. <br>
<br>
Please provide "factual evidence" that it adds to OSM accuracy.<br>
Please provide "factual evidence" that they are actual "fixes". <br>
<br>
"MapRoulette gets help to some of the remote, forgotten places."<br>
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.<br>
<br>
OK. First random from your site:<br>
<a href="http://maproulette.org/#t=IT_WaterCrossings/IT_RXING_11.333811432368_43.474069354879" target="_blank">http://maproulette.org/#t=IT_WaterCrossings/IT_RXING_11.333811432368_43.474069354879</a><br>
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? <br>
<br>
<a href="http://maproulette.org/#t=osmose-8170-147-soccer/osmose-8170-147-soccer-None-d19295cc3e005283ae80b66bde86f474" target="_blank">http://maproulette.org/#t=osmose-8170-147-soccer/osmose-8170-147-soccer-None-d19295cc3e005283ae80b66bde86f474</a><br>
Supposed missing soccer pitch in France. I mean, really? <br>
<br>
I believe these sites add more inaccuracy than accuracy.<br>

<div>Hello All<br>
<br>
Please include all replies to OM-Talk:<br>
<br>
I was meaning to start a separate thread on this
subject, but this
seems the appropriate time & place.<br>
<br>
This website, along with <a href="http://osmlab.github.io/to-fix/" target="_blank">http://osmlab.github.io/to-fix/</a>
( & maybe others) are encouraging errors to be
introduced to
the OSM database.<br>
<br>
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. <br>
<br>
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?<br>
<br>
IMO these websites are detrimental to the OSM database
& should
be rescinded. <br>

Hi all - just wanted to let you know that the ‘Ways

used to consist of mostly false positives for the past

there still are some, but there should be some fun to

still :)</div>
