<DIV><FONT face=Arial size=2>I may be wrong, but I'm not sure that Mapnik yet
supports the tag waterway=riverbank, which may be why there is such a jumble of
tags applied to the ways making up the Thames.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In theory (leaving aside the question of tagging
tidal rivers) the only required tagging is waterway=riverbank, but if
Mapnik doesn't support it I assume people have being adding natural=water, and
in places natural=coastline to try and force the rendering in
mapnik.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>This has led to some ways being tagged as natural =
water, natural = coastline, waterway = riverbank.</FONT> <FONT face=Arial
size=2>When you throw in the fact that ways tagged as natural = coastline
don't need to be in relations to correctly show islands, but it is suggested
that relations be used on the tags waterway = riverbank you get a complete
mess.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Whilst the relevant ways could be tidied up,
and just tagged as waterway = riverbank, there seems little point in doing so
until Mapnik supports this tag, as someone I am sure will come along and retag
natural = water, natural = coastline to try and force the rendering
again.</FONT></DIV>
