I am thoroughly bemused by the widespread attitude of "if it isn't in OSM, it doesn't exist". OS OpenData is a fantastic resource and, believe it or not, you can use it outside OSM. In most ways it's easier to use than OSM: the data quality is consistent, everything is neatly layered, you don't get some roads drawn at 1pt/500m and others at 1pt/2m, the .shp format is an industry standard, and, of course, OS/CO chose a sane licence. And people _are_ using it. I spotted a major national charity the other day which has just started using VectorMap District. There are iPhone apps using it. I produce three or four maps for Waterways World every month using Meridian2, and am just about to make a couple of cycling maps for West Oxfordshire District Council using VectorMap District. So. The data consumer has two choices. a) They can have consistent, reliable data with national coverage right now. That's OS OpenData. b) Or they can have glorious rich data which doesn't have national coverage _yet_. That's OSM. If we import OS OpenData into OSM, then OSM becomes national *but* is no longer rich. Because no-one is out there trudging the streets, because no-one cares for the data, it becomes sterile. I note, once again, that the Worcester estates that someone "helpfully" traced from StreetView last year are still bereft of most of the footpaths and half of the road names. So we lose the chance of a real, community-built map of the UK. Meanwhile we have helped precisely no-one, because the complete data *already* exists and is *already* usable. Can't we actually have a go at doing it ourselves and finishing the UK this year? Say "right, let's look at a bot in spring 2012, but we have a year to get this right"? I'll do a town this weekend if you will. cheers Richard -- View this message in context: http://gis.638310.n2.nabble.com/Adding-a-further-250-000-UK-roads-quickly-using-a-Bot-tp5986539p5992349.html Sent from the Great Britain mailing list archive at Nabble.com. _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
