I second that, GNS in Ireland is a little bit like TIGER in the USA: good to have at the time, but showing its poor quality today. GNS data can correspond to different "modern" OSM data, from cities to uninhabited localities. Whenever you can, you should improve the GNS data by moving it into proper position, or even replacing it with the corresponding townland or residential area if it matches (one shouldn't have two osm objects for the same physical thing). Concerning the tags, all the "gns:"-prefixed ones are either redundant or useless, and can be deleted if you happen to be modifying the node. Same goes for "created_by" (I think josm removes that one automatically) and the note. Keep the source tag, but don't hesitate to amend it if you used other sources this time around. _______________________________________________ Talk-ie mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-ie
