The issues are real, but we disagree on how big they are. I'm of the opinion that they aren't worth fussing over, but YMMV. > * design a sophisticated computer algorithm to calculate the size of bays > and derive bay importance from this Finding the size of an area is actually much simpler than your proposed algorythm. It's implemented in stock PostGIS. It doesn't involve tuning or heuristics. It's aready used in many places in the default osm rendering (osm-carto). It is done at import time and is "free" from the map designer's POV. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
