IIRC, OpenRailwayMap team was evaluating this option last year but eventually decided to use another approach. Nevertheless, updating a database with specific tags only (in this case railway=*) or a certain bbox should still be feasible. If you're interested, check out [1]. There's also 'Show me the way' [2] as one well known user of Augmented diffs. Obviously this is not in any way related to updating a local db. hth, mmd [1] https://github.com/drolbr/Overpass-API/issues/139 [2] https://osmlab.github.io/show-me-the-way/ _______________________________________________ dev mailing list [email protected] https://lists.openstreetmap.org/listinfo/dev
