Or where the elevation dataset doesn't include a deep canyon, which causes a straight bridge to appear curved. If it's a railroad, you can be pretty sure it isn't. If it's a road bridge, you have to rely on what you saw when you were there. -- --my blog is at http://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
