The low (web friendly) resolution of the image coupled with the further, cascading loss of resolution going through QGIS's geo-reference tool meant that near to +- 1 kilometre accuracy. After about 10 attempts I only have 3 roads running along the wrong side of coastline and several coinciding with their counterparts in the historic=roman_road data. I had lost the link to that site so thanks for that. mick _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
