This was meant as an example - i did not specifically have this application in mind. Using the coastline to determine the distance of some object to the coast would be equally suited. The point i am trying to make is that for applications other than map rendering consistent placement of the coastline-river transit is important as well. Using water salinity as a criterion will not work since there often is no continuous transit from freshwater to saltwater but a layering with freshwater on top and the heavier saltwater below. Apart from that fast flowing rivers can reduce the salinity quite far out into the ocean. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
