In the UK and I suspect most places where people live a river is a constrained channel of water. It is mapped on OSM like a road and the reality is that that mapping is a very good representation. However... in a wilderness, rivers may not be so polite. For example, a river that carries melt water may be 50m in width in winter and 300m across in summer. I have been mapping the 300m size as the riverbank ... but should I be? asked 30 Jan '12, 12:40 RobChafer |
