All UK ways and relations tagged with either amenity=school or amenity=college will get picked up by my tool at http://robert.mathmos.net/osm/schools/ . I then attempt to match these OSM objects with the schools on the official lists. Any ref:edubase, ref:seedcode and ref:deniirn values are used on a first pass, but after that there is a second pass that matches each unmatched school on the official list to the nearest OSM object within 1km that hasn't yet been matched. In rural areas (schools generally more than 1km apart) this works very well. In urban areas the tool can often match things the wrong way. But a match will still correspond to a school in OSM being counted, even if it's an incorrect match. So apart from some of the matches in the tool being wrong, almost everything should still be counted. (The exception is if there's a missing postcode in the official data, or the actual location of the school is more than 1km from the postcode centroid. Then the match won't happen.) Hope that helps, Robert. -- Robert Whittaker _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
