Penso che questo riguarda direttamente il nostro "territorio" ---------- Forwarded message ---------- From: Frederik Ramm <frede...@remote.org> Date: 2 May 2017 at 11:05 Subject: [Tagging] Very large multipolygons To: "Tag discussion, strategy and related tools" <tagg...@openstreetmap.org>
Hi, I have removed three very large multipolygons from OSM today. * I DELETED a "place=sea" for the Adriatic Sea (http://www.openstreetmap.org/relation/4590486) because I think we shouldn't even start with that kind of thing (place=ocean name=Atlantic anyone?). * I CHANGED a "type=multipolygon, place=peninsula" to "type=boundary, boundary=land_area" for the Italian Peninsula ( http://www.openstreetmap.org/relation/4056532). * I CHANGED a "type=multipolygon, place=region" to "type=boundary, boundary=region" for the Alps (http://www.openstreetmap.org/relation/2698607) even though I have a feeling this should be deleted altogehter (the Alps are not an area as sharply defined as this relation suggests). I became aware of these because a while ago I've started including cross-border multipolygons in the extracts I publish on download.geofabrik.de, and these huge multipolygons are somewhat of a disturbance, leading to the Switzerland extract containing the Danube river in Vienna (which forms part of the "Alps" boundary), or the Austria extract containing the outline of all of Italy because of the "peninsula" multipolygon. I realize that what I've done here is close to "mapping for the data extractor" and I'm offering these decisions for discussion here. I definitely think none of the three areas qualifies as a proper "multipolygon" and *if* these huge areas need mapping, then some solution based on "boundary" is better.
