I disagree. As I understood it, monitoring:water_level is for regularily *monitoring* of the level, whereas the tagging searched for is for markers of exceptionell historic high water levels. Of course, sometimes the high water marks are placed at water level monitoring stations, but often they are placed at buildings that are quite distant from the water, to display the impact of the high water. IMO historic=memorial + memorial:type=plaque is the right direction. meillo _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
