In some areas we are beyond the aerial imagery so as long as people KNOW that the fine detail they are being shown is wrong then OK, but this may well be well mapped detail not something that actually NEEDS 'smoothing' ... especially when the selection of imagery available does not always line up exactly with one another. I'd rather not see some of the list on maproulette applied to the UK and I'm sure other European countries would feel the same? We have some very fine detail now being mapped and any smoothing algorithm wuold have to be very cleaver not to affect that. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
