check out the d.rhumbline, d.geodesic, r.transect, r.profile, and m.cogo modules. also install the "proj-bin" package (assuming linux) and you get the "geod" program which will calculate the start and end points for you using a great-circle calculation. are you using a lat/lon location? how large an area will your plot cover? continental?
