I started with some low-res images of roads from Bill Thayer's "LacusCurtius" site: http://penelope.uchicago.edu/Thayer/E/Roman/home.html and after a dozen or so tries managed to get a layer that varied between 10 metres and 5 km error and am in the process of re-aligning that with the sections of Roman roads from OSM (results from using the search for "roman" in QGIS->attribute table). I am also working through "Roman Roads in Britain" by Thomas Codrington to find useful information. I must have had a "blond moment" when I tried searching for "start_date" as I got no results there. I have a small list of references to search for but I just thought/hoped some mappers might have bits they have done that don't fit the "visible on the ground" requirement. Copyright and licencing is a concern as I don't really understand the relevant laws. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
