I would like to raise the issue of tags for *waterway=river*, *waterway=stream* and* waterway=wadi.* The problem that exists with the existing tags is that there is no visual difference on the map for a stream (perennial) and a stream (intermittent) and the only other option is wadi which gives a blue pecked line. Accepted mapping standards for this would be to show:- all perennial rivers and streams as a continuous solid blue line (indicating that there is flowing water all year round) all non-perennial rivers and streams as a continuous blue pecked line (indicating that there is flowing water during the wet season but not the whole year). A wadi would be depicted with a continuous pecked brown line (indicating that it is dry watercourse and could be dry for years at a time...only flowing if there is a flash flood or unusually heavy rain). This would then convey the correct meanings with symbols on the map and make reading the map a lot easier. The categories would still be searchable and distinguish between the three categories of water flow. The proposed tags would then be *waterway=river* ...... *waterway= stream* ...... continuous solid blue line *waterway=river_intermittent ...... waterway=stream_intermittent ..... *continuous pecked blue line *waterway=wadi* ..... continuous pecked brown line (a wadi can be so wide that another tag would be needed similar to the tag for river banks) *waterway=wadi_bank* which would still be a brown pecked line. This would then ease the path for introducing the tags for perennial lakes with a solid blue outline and lighter blue fill, intermittent lakes with a blue pecked outline and a light blue fill and dry pans with a brown pecked outline with a brown stipple fill. I can figure out a single tag proposal on wiki but do not know how to do this more complex proposal as it entails changing all the tags at the same time along with their map symbols. If it is deemed appropriate is there someone who could do this? Reference...... http://pubs.usgs.gov/gip/TopographicMapSymbols/topomapsymbols.pdf
