You'd need a very fine grained elevation model for that to be the case. One reason people want steep inclines marked is to determine wheelchair access. A stretch of even 5 metres at 15% is important. And still important even if it's under trees or a building or wherever, out of reach of an elevation-surveying satellite. Steve
