Your right, my mistake. There is no need to add 'natural=water' to the 'waterway=riverbank' tag.
And that sounds right, the land that is partly covered has and 'surface=undefined', so natural=marsh would not fit, nor wetland=marsh. (local folks would know) http://wiki.openstreetmap.org/wiki/Tag:waterway%3Driverbank "I like to mark riverbanks on its high-water extent, including sandbanks. Therefore non-permanent islands (sandbanks) are also included, only permanent islands are marked. " It seems that is just a matter of opinion (like everything else), . ... since we have the data, and it would help river canoeists to know where these are. .. i think it should be added. ... (if i was canoeing down that river (with a remote control - gps guided canoe) .... would be nice not to get stuck in sand... ... except my eyes shouldn't be on the device while paddling... but that is not the point :-) ... a nicer looking map is.. ..... perhaps since we know that it is "undefined" .. why not tag it as "fixme=surface is undefined" ...? But i do think that 2 separate proposal pages need to be made for 'water=intermittent' and 'water=tidal', & splitting the examples would help, as we can explain the reasoning for each on 2 pages. So it becomes 2 sub-values for waterway=riverbank ... thats all i got for now. .. this is a tuff one.. :) ... hopefully someone can help with this/these proposal page(s) Sam On 3/23/10, Bégin, Daniel <[email protected]> wrote: > Hi Sam, and others! > > Sam wrote "I worked on a sample here, just outside of Empress, Alberta (in > Saskatchewan) [...] So i think that waterway=tidal should be used, with > natural=water".
