It does not provide height, but it provides ordering. Which is still real world data, just less granularity. >> In the case of tag saying what angle to draw something, that's a >> specific drawing instruction, and I don't think it belongs. > > Along with an angle, a position tag for the label would be useful to > avoid annoyances where it renders outside the perimeter of > irregular.shaped polygons. So would saying that a particular object should be green. Once you add specific drawing instructions, I don't see how to draw the line. Can this really not be computed by renderers? It just seems like an optimization problem. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
