[landcover] rendering natural=wetland, wetland=* differently

The tag natural=wetland can be used with additional wetland=wetland_type tags (wetland=bog, wetland=mangrove, ...). I produced a set of bitmaps for seamless rendering that possibly could be used for wetland rendering and uploaded them to wiki.openstreetmap.org

So far, apparently wetland=bog (and the old natural=marsh) are rendered. If you find my bitmaps suitable, I would be happy if you could implement the rendering of the respective wetland types.

Thanks for your attention!
All the best, Ulf

The area in

may serve as a test case; areas tagged with wetland=mangrove and wetland=marsh are currently invisible. An area where I did not change the older tagging (natural=marsh) is rendered.

landuse=wetland rendering has been in since June. Renders the same as natural=marsh.

For natural=wetland, wetland=tidalflat which the wiki describes as "Tidally inundated areas of bare mud, sand or similar sediments", I'd prefer a solid colour looking something like wet sandy mud if possible, please. I've been using the OS Opendata to try marking the Mean High Water as coastline and the Mean Low Water as an outer way of a natural=wetland, wetland=tidalflat multipolygon and it needs something a little more solid to make the Mean Low Water level clearer - the marsh symbol currently rendering for natural=wetland is just a bit vague. http://osm.org/go/0EH4HacT-- is an example, but as I write still shows old coastlines. Thanks.

I agree with EdLoach that it is important that natural=wetland is not all rendered the same.

It is incredibly frustrating trying to get local mappers to use natural=wetland along with for example wetland=tidalflat when all natural=wetland renders just as marsh (wetland=marsh). There are over 450 uses of wetland=tidalflat in OSM for example, often covering large areas - these areas deserve better rendering.

I agree with the sentiment of this ticket. I would however, suggest that the renderings be given a non-transparent background. It would help to delineate the area and a suitable choice of colour would add more meaning to the rendering. e.g. the existing rendering for "natural=mud" would work just fine for the "wetland=tidalflat" tag.

Below two emails by Lennard and Steve, explaining mapnik-team's next step. Steve has contacted Twain asking whether he could design some appropriate wetland fills.

has been in the pipeline for a very long time. What can we do to get
this resolved?

Thanks for considering ...

I've asked steve8 if he could look into that one, a while ago. The
problem was twofold: wetland=* needed to be imported as a tag (this part
is done IIRC), and the supplied example bitmaps were not entirely to taste.

Steve, do you remember how far along you got with this?

This is now being discussed on Github: gravitystorm/openstreetmap-carto#545
Therefore, I will close the issue here.

This is in fact different from the issue on Github, so I reopen it here.
