no it is not (only, IMHO), it is an attribute to get some depth into a 2D-model (our database). It is a tag that indicates which object lies above which in the real world, but a renderer could well decide to render stuff in different order (e.g. for a tunnel you can decide to render it above all other stuff with appropriate line style, so you can see it, there is not always sense in rendering stuff to the drawing in the stacking order the stuff is arranged in the world). cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
