water stroke is too thick at low zooms

[almccon]

Probably not necessary at low zooms. I recall that we depend on water outlines at high zooms, but I don't remember exactly why.

@almccon could you clarify this?

[almccon]

The water outlines are the same color as the water, so they're hard to spot, but at this zoom they are so fat that they spill onto the land. Denmark, for example, looks almost totally flooded.

Ah, okay that should be an easy fix (fingers crossed) thanks for clarifying.

@almccon seems like the culprit could be here: https://github.com/stamen/terrain-classic/blob/master/map.mss#L84-L92

However I'm not able to replicate this issue. When i change the color of the stroke it seems like it's already fairly thin. I do think the coastline generalization should change though. For example we should probably use the ne_50m_ocean at lower zooms for the coastline rather than the ne_10m_ocean which looks a little too detailed.

this is zoom level 4:

Yes, maybe it is thin, but even with those thin lines, they still wash out the land when they're the same color as water. Check out how wet Finland looks at that zoom:

But it's true that the problem isn't that bad at zoom 4. Zoom 3 is worse. Maybe we need to remove the lines entirely at zoom 0 through 4. Shouldn't have any unexpected consequences, I hope.

@almccon I feel that leaving out the stroke for water polygons at low zooms would be fine.

Alternatively we could play with using the ne_50m_ocean layer which has a more generalized coastline and/or making the coastline a darker stroke.

[clhenrick]

@almccon changing the water line stroke to 0, map background color to water for low zooms and using the ne_50m_ocean layer for the coastline seems to resolve this:

Works for me. :ocean:
