That's too bad. More than 90% of node ids are completely useless as they refer to only one way. This is a significant drag on the database, and especially on imports (especially under the current .osm format which requires a huge sort and join in order to import into a form suitable for rendering). Node ids could still be kept for nodes which reference more than one relation/way, as well as for POI nodes, but 90% or so of them could still be eliminated/recycled with very few changes. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
