[Talk-GB] 10 fascinating facts about OSM & OSGB - 2014

[Robert Norris]

Happy 10th Birthday OSM!

For a 10th birthday present - I thought I'd reprise SK53's 10 fascinating facts posting from April 2013[1],
 to see where OSM GB is at, at of the beginning of August 2014 compared to Ordnance Survey GB(OSGB)[2] (values not updated).

So here's the comparison with the changes in OSM in that period.

   Object: OSGB ; OSM ; OSM Change since April 2013

   1. Pylons: 80,517 ; 69,562 ; +11,075
(<http://taginfo.openstreetmap.org.uk/search?q=tower#values>)

   2. Post Boxes: 93,728 ; 47,501 ; +4,759

   3. Camp sites: 8,908 ; 3,826 ; +644
( 1493+3+1+1camp_site<http://taginfo.openstreetmap.org.uk/search?q=camp_site#values>)

   5. Bus Stops: 354,099 ; 220,490 ; +4,770

   6. Residence within 500m of a football ground: 2,115,006 ; Not analysed ; Not analysed [3]

Of course there is no guarantee we are comparing like for like.

All values from UK taginfo (except for road length[4], which is sum of the lengths of the following highway types:

living_street          250.9 km

trunk                27320.7 km
trunk_link            1716.6 km
unclassified        128275.3 km

[3] Some SQL query code may be needed to perform this one - for OSGB given the high number of homes, presumably they are considering any football pitch (not just league football grounds). I still haven't gotten around to doing any DB things...
