You have some conflicting goals here - you want to maintain the OSM tagging information on the way level so you need to maintain the individual ways - which however limits what you can do in terms of rendering - dashing is not consistent for example where a boundary is split and you have problems doing geometry processing (like the all popular ST_Simplify()). IMO a process that merges the ways where it is non-ambiguous would be more useful. And most cases where tagging varies in an admin boundary without there being a junction that is a tagging error. The maritime attribute based on tagging is currently of very limited use since it is not consistently applied. On admin_level 2 a better way would be to classify this based on topology - i.e. all boundaries that are only part of one admin_level 2 relation are maritime boundaries. On the higher admin levels this is more complicated of course and not easy to solve. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ dev mailing list dev@openstreetmap.org https://lists.openstreetmap.org/listinfo/dev
