Agreed that routing is a really important use for place nodes. Many settlements have an obvious 'centre point'. In Oxford it's Carfax, in Cambridge it's the Market Place / Great St Mary's, in Gloucester it's the main crossroads, in Leicester it's the Clock Tower, in Peterborough it's the square outside the Cathedral, here in little old Charlbury it's the crossroads by the Rose & Crown, and so on. London's routing centre is famously Charing Cross. A place node is a good way of mapping this. But when a place node is arbitrarily situated, or isn't present, routing instructions tend to start/finish at an obscure alley somewhere. I've recently moved several place nodes to these centre points for exactly this reason. I'd slightly modify Philip's advice, though. I don't think accessibility of car parks should be a consideration. OSM data is used for all modes of transport and we shouldn't make value judgments that favour motor traffic. Better to choose the established/historic centre point - i.e. a factual approach rather than simply "tagging for the router". :) cheers Richard -- View this message in context: http://gis.19327.n5.nabble.com/Missing-place-city-nodes-Manchester-Leeds-tp5758812p5758845.html Sent from the Great Britain mailing list archive at Nabble.com. _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
