Sorry, I did not get it. How saving only vertexes is better than having a polygon (made out of those vertexes)? Full geometry is required to be able to calculate label positions on all scales. For small scales this could be a simple curved line (calculated from polygon geometry), for large scales it could be a lot of labels placed/scattered on the same polygon geometry and approximating (simplifying) such polygon too much would decrease number of labels placed or labels would be placed outside of an object which is even worse. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
