I think there is currently no comprehensive list of practical direct effects this has. The most significant ones are likely various differences in the way polygons are interpreted and rendered. Of these differences the most prominent one is probably due to loading each multipolygon relation as a single feature into the rendering database (osm2pgsql -G option) rather than splitting it into separate components. This makes a strong difference w.r.t. rendering of labels for administrative boundaries. However this is not mainly what we are asking for feedback here since this is a change which is already well known and well tested in its effects. We are also aware that this change will likely require tuning the style in terms of label placement in the long term - which is however not a point of concern right now. Where feedback is most useful are the more suptle changes which will only have a visible effect in a smaller number of situations. See the PR Paul linked to for details. In particular it would be important to know if there are situations where the new database schema leads to incorrect mapper feedback through the the way things are rendered. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk
