BRAVO ! I started a talk on the same idea on the french osm-dev-fr list.
About relations, the need to reconstruct their geometry is depending on their final use where ways geometry are mostly needed and I feel they are more resource hungry. A few questions... When the change on a node or way is just a tag change and does not involve geometry change, are the diff still providing all linked nodes/ways ? It would be great to have a clue in the diff that it is just a tag edit and not a geometry edit, this would save the geometry reconstruction processing... Next step is to update osm2pgsql and similar tools ;) 2012/8/27 Roland Olbricht <[email protected]>: > Dear all, > > > > Overpass API now offers Augmented Minute Diffs.
