Dave, OSM is by far the best free geographic database in the world, but we have anomalies which need to be addressed. MapRoulette helps address these kinds of problems and brings to light errors which might not otherwise be seen or fixed.
Many tasks do require local knowledge, but there are also many which only require some common sense, or ability to read a photograph. MapRoulette taps into that community potential and has incredible results to show for it. MapRoulette is not substitute for going out and mapping, but no one has argued that it is. I did not see much in your email that was actionable. That is, I didn't see any practical suggestions for improving MapRoulette. Perhaps if you have some, you can share them with us and we can integrate those ideas. - Serge On Fri, Aug 22, 2014 at 9:03 PM, Dave F. <dave...@madasafish.com> wrote: > 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.
