I thought that we’d imported the NAPTAN dataset, which should mean we have ALL the bus stops in the UK? So why do OSGB have more?

I thought it would be fun to compare with OSM 1. Pylons: 80,517 ; 58,487 (OSM<http://taginfo.openstreetmap.org.uk/search?q=tower#values>) 2. Post Boxes: 93.728 (OSGB); 42,742 (OSM<http://taginfo.openstreetmap.org.uk/search?q=post_box#values>) 3. Camp sites: 8,908 (OSGB); 1 274 (camp_site<http://taginfo.openstreetmap.org.uk/search?q=camp_site#values>) + 1 918 (caravan_site<http://taginfo.openstreetmap.org.uk/search?q=caravan#values>) = 3,192 (OSM) 4. Buildings: 35,397,754 (OSGB); 1,890,835 (OSM<http://taginfo.openstreetmap.org.uk/search?q=building>) 5. Bus Stops: 354,099 (OSGB); 215,720 (OSM<http://taginfo.openstreetmap.org.uk/search?q=fuel#values>) 6. 2,115,006 (OSGB); 7. Petrol Stations: 7,702 (OSGB); 5,197 (OSM<http://taginfo.openstreetmap.org.uk/search?q=fuel#values>) 8. Addresses: 27,341,262 (OSGB); 532,886 (OSM<http://taginfo.openstreetmap.org.uk/keys/addr:housenumber>) 9. Electricity Poles: 183, 987 (OSGB); 94,199 (OSM<http://taginfo.openstreetmap.org.uk/search?q=pole#values>) 10. Road length: 407,532 km (OSGB); 522,627 (OSM) Of course there is no guarantee we are comparing like for like (although its only power=pole which looks suspiciously high, I suspect we map low power lines not included by OSGB). All values from UK taginfo (except for road length, which I queried from a snapshot schema), no data merging or need to query multiple sources, and certainly no need for an IBM Netezza appliance. I thought I'd add a few more quirky OSM values: 1. 5<http://taginfo.openstreetmap.org.uk/tags/royal_cypher=EVIIIR> post boxes with Edward VIII's royal cypher 2. only 110<http://taginfo.openstreetmap.org.uk/tags/memorial=war_memorial> War Memorials 3. 1830<http://taginfo.openstreetmap.org.uk/search?q=police#values> Police and 1518<http://taginfo.openstreetmap.org.uk/search?q=fire#values> Fire Stations 4. 847 Fire Hydrants (see above) 5. 1378<http://taginfo.openstreetmap.org.uk/search?q=real_ale> establishments purveying Real Ale, and 156<http://taginfo.openstreetmap.org.uk/search?q=cider> Real Cider out of 32,624 Pubs <http://taginfo.openstreetmap.org.uk/search?q=pub#values> and 1717 Bars<http://taginfo.openstreetmap.org.uk/search?q=bar#values> (including 1 with ale_supply_limited, and ONLY 1 with osm:london=approval<http://taginfo.openstreetmap.org.uk/keys/osm%3Alondon#overview>) 6. 4771<http://taginfo.openstreetmap.org.uk/keys/bicycle_parking> Bicycle Parking locations 7. around 300http://taginfo.openstreetmap.org.uk/search?q=hide#values bird/wildlife hides 8. 2<http://taginfo.openstreetmap.org.uk/search?q=knitting#values> knitting shops (shows gender of mappers I suspect) 9. 5552<http://taginfo.openstreetmap.org.uk/keys/stile#values> stiles 10. 1774<http://taginfo.openstreetmap.org.uk/search?q=lock> canal locks Jerry Please Note: Any views or opinions are solely those of the author and do not necessarily represent those of Independent Television News Limited unless specifically stated.
