Shades of green are confusing
Open, NormalPublic

Description

The current map style has confusing shades of green



It's not obvious from the cartography what the five different shades mean. I can't identify what some of them mean, and I'm familiar with both map rendering and the area being rendered.

For reference, in this screenshot the top-right is national park, bottom-left is wooded area, and the other corners are the two combined.

In the second screenshot from the top the top-left has graveyard and buildings in graveyard. The third screenshot has buildings in park (non-national).

Not shown are buildings in woods and building in woods+park, each of which have their own tints of green.

The cause of many different shades is using transparency, and the design anti-pattern of using a strong colour and toning it down with transparency.

Starting with the national parks, since I've just added them to brighmed:

One of the better styles I've seen for national parks is a strong outer line and line inside the border, and very light green shading inside.

The US NPS uses this

As does OpenStreetMap Carto, which uses it only for national parks and nature reserves, not leisure parks.

For webmap cartographic conventions, it varies.

  • Google has switched around a few times, using all possible combinations of showing trees and showing national parks. They also change for the different style variations and zooms.
  • Michelin does a light green fill for parks and shows no physical landcover features
  • Stamen Terrain shows terrain and no national parks

My preference is for the NPS style if we're going to show national parks. It makes the quasi-administrative nature of the polygon clearer and the boundaries, and also works much better with parks that have water inside them.

This was to be done in the new style stuff, which is no more, so it's now an issue again.
