Wetlands styling

[kylebarron]

I noticed some disconnected streams (center of image), and discovered that it's because wetlands aren't currently given any styling. https://maputnik.github.io/editor/#15.27/44.10019/-71.576018

This is defined as class=wetlands within landcover in the OpenMapTiles schema (And as natural=wetland within OSM):

The default OSM basemap uses a custom pattern:

Should these polygons be given a style in OSM Liberty, and if so, what should it be?

Nice find @kylebarron

Should these polygons be given a style in OSM Liberty, and if so, what should it be?

Yes, we should style these. Currently we are using only a pattern for the road_area_pattern, for wetlands maybe using a light plain color or a sparse pattern which is less obtrusive?

Open for suggestions.

Maki does have a wetland icon: https://github.com/mapbox/maki/blob/master/icons/wetland-11.svg

It doesn't look very good to just add the wetland icon in the current sprite:

A simple wetland icon without the bordering circle might look good, but I haven't figured out how to edit the sprite yet.

There is a Maki editor: https://labs.mapbox.com/maki-icons/editor/ Or you could use https://inkscape.org to modify the SVG.

There is no need that it would be part of the iconset, because it is no POI. We are having also SVGs which are not part of the iconset, like the fill pattern for the pedestrian_polygon: https://github.com/maputnik/osm-liberty/tree/gh-pages/svgs/svgs_not_in_iconset

from: https://docs.mapbox.com/mapbox-gl-js/style-spec/#paint-fill-fill-pattern

For seamless patterns, image width and height must be a factor of two (2, 4, 8, ..., 512)

You could use https://github.com/mapbox/spritezero-cli, it is described here (bottom of that page): https://github.com/maputnik/osm-liberty#icon-design

What do you say about that ?

[pathmapper]

Hey @jpbede, thanks, looks promising!

Would you like to submit a PR so we could evaluate how the pattern behaves for different zoom levels?

[jpbede]

Sure. Created the PR 84
