Hello everyone, This is a small issue that came up recently in Brazil. In my understanding, the layer tag has no specific meaning other than to specify a rendering order. The wiki, however, states that it is wrong to tag a whole river with layer=-1. The reason for that, as far as I could figure, is because current validators (such as JOSM's or KeepRight's) will not issue a warning on a waterway x highway crossing when their layers are different, leading some users into tagging the river with layer=-1 in order to get rid of warnings about missing bridges and tunnels. So, I think that the validation rule is inadequate: it should warn when a waterway crosses a highway that has no bridge or tunnel tag, regardless of the value in the layer tag. (Fords are the only exception, AFAIK.)
Do you agree that the river can be tagged with layer=-1 as long as this value is correct in relation to the layer of other nearby/crossing ways? -- Fernando Trebien +55 (51) 9962-5409 "The speed of computer chips doubles every 18 months."
