Sorry - I think my previous email came across badly... anyway: You make a good point - I was thinking of the number of points in terms of the quality of the output I want but it probably makes more sense to think in terms of the reliability of the input data. A guideline of 'the limit of the quality of your GPS / data source' sounds like very good advice. It comes down to that fundamental conflict of the whole OSM project - what we capture is data but what most of us want out of the end is good quality maps! -- Brian _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
