Doesn't mean they shouldn't be updated/added if there is a better tag... > The suggested term floodgate would be more intuitive for me as a none native > speaker - if the term fits for native speakers as well. I actually think we need some way to indicate scale, wikipedia seems to indicate sluice gates are usually on the small side of things, spillway gates are usually much larger, for a good example of spillway gates see the photos Liz linked to of Wivenhoe and Somerset, those dams were specifically built to reduce or prevent Brisbane (state capital of Queensland Australia) from flooding. In fact Wivenhoe was upgraded in recent times to hold 200% normal operating capacity. As for floodgates these aren't usually closed except in times of flooding and should be tagged differently again so they can be rendered differently for those that care about such things. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
