For simulation purposes. Aerial photographs can be used too, of course, but it is quite time consuming to measure the distances that way. Curves are also an issue that I hope the GPS will do away with. > and how do > you intend to distinguish them from a lateral track defect? I don't know if it can be done automatically. The idea is to detect the common crossing as the wheels pass over it, and maybe you can tell from the accelerometer readings that only wheels on one side ran over something or perhaps the data show a particular signature from the common crossing that a lateral track defect doesn't have. -- Rask Ingemann Lambertsen Danish law requires addresses in e-mail to be logged and stored for a year _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
