Using the great OSM maps over the last years, I remarked recently a confusion of the Red Cross Sign (used on medical institutions in OSM) and the Swiss Flag. When travelling around the world, the Swiss Flag (red ground, white cross on it) is often used in health care contexts instead of the Red Cross (white ground, red cross on it).
Ok, Thank you for reply. I can see that this has already been discussed before. Still I think that replacing (“inversing”) the sign would be useful. But I certainly understand the problem of protectivity by the red cross (although it does not really make sense for them to protect their own sign, does it?)
