So you have said repeatedly. I know this is hard for native English speakers but you need to accept that tags in OSM do not generally mean what the English language terms they use mean. intermittent=yes in OSM currently means quite precisely what the OSM wiki says it means: "The intermittent=* key is used to indicate that a body of water does not permanently contain water." This includes at least a few 100k features you would define as ephemeral. You can't change that with a proposal. There is a reason why such a broad and undifferentiated tag has become popular in OSM despite there being more differentiated concepts in existence: Because more differentiation here is in many cases practically non-verifiable. No matter if mappers observe on the ground or via images, the usual case is they see the waterbody in a dry state but see clear indications of recent water cover or water flow hence they can assume a non-permanent waterbody. This is what you can currently indicate via intermittent=yes. But requiring mappers to guess what kind of time pattern the change from dry to water cover follows does not work. Offering this as an option in case mappers have more in depth knowledge is a good idea, i said that in the past. But making it mandatory is bound to fail. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
