+1, I noticed this in Rome too. I think It is almost impossible to correct the errors of badly conversed/rectified/stiched pictures, or in other words: if the original picture is too big you will get noticable artefacts when assembling them. Easiest to notice are curvy lines that are straight in reality, as you pointed out. cheers, Martin _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
