difference in area styling between forest tagged as natural=wood and landuse=forest is much greater than between landuse=forest and landuse=farmland

[mkoniecz]

What steps will reproduce the problem?

1. edit in area where some mappers used landuse=forest for forested area and some used natural=wood for forested area
2. start adding landuse=farmland

What is the expected result?

Map in edit mode is readable

What happens instead?

Map in edit mode is highly confusing

Please provide any additional information below. Attach a screenshot if possible.

I think that the same or at least very close color for landuse=forest and natural=wood would be preferable as there is much smaller (if any) difference between landuse=forest and natural=wood

In image on the right distinguishing pale green representing forests and pale green representing fields is nearly impossible.

real data example is from ​https://www.openstreetmap.org/#map=15/49.5793/21.9036 region

Or make landuse=farmland a little more yellowish? (#ccd280 for this example)

Top: natural=wood, landuse=forest, modified landuse=farmland
Bottom: natural=scrub, landuse=grass, leisure=park

[mkoniecz]

Yellowish should solve that...

Yellowish would be close to schools and parkings but this features have completely different shapes and are typically not next to fields.

BTW, is it possible to apply pattern to areas rendered in JOSM? Maybe tree pattern like in OpenStreetMap Carto would help?

And thanks for reminding about other vegetation!

I see one more problem: natural=scrub and natural=wood are extremely close (if I would look at it for the first time I would expect these two to represent natural=wood and landuse=forest) (but it may be solved as a separate issue) - landuse=forest is much closer to natural=wood than to landuse=grass or natural=wood is to natural=scrub and rendering should reflect it.

I didn't have success in fill-image and fill-color at the same time https://josm.openstreetmap.de/wiki/Help/Styles/MapCSSImplementation#Areastyles

It looks like the pattern stands out and we can't use a background with some color.

area[natural = wood] {
        fill-color: green;
        fill-image: "tree";
        fill-opacity: 0.5;
} 

(tree is just a simple tree.png file with a small tree)

I am unsure it JOSM doens't support this or if I don't know how to properly specify the style :-)

See #17095 which is about ​https://pasharm.github.io/New_basic_style_for_JOSM/New_basic_style.mapcss

I am planning to work on it finally, though I am aware that forest topic is quite controversial and some people are convinced that there is meaningful difference in how landuse=forest and natural=wood are used.

So, question to JOSM developers: is it OK top remove distinction between landuse=forest and natural=wood in JOSM map style rendering?

[skyper]

I'd prefer a similar but not the same rendering like same icon but little different outline color.

[Klumbumbus]

For most map renderers it probably makes sense to use the same color/style for landuse=forrest and natural=wood. For editors like JOSM I think it makes more sense to have an distinction so that users can see what is actually tagged.

I planned to make the farmland yellowish like already suggested.

[mkoniecz]

area[landuse=farmland] {
    fill-color: farmland#b8e0b1;
}

Any idea what farmland before #b9e0b1 is doing?

I tried looking at https://josm.openstreetmap.de/wiki/Help/Styles/MapCSSImplementation#Areastyles but I jave not found an answer, the on;y case of something similar was default: colorDisplayCustomPref#FF00FF; but it has no explanation from what I see.

[Klumbumbus]

Replying to mkoniecz:

Any idea what farmland before #b9e0b1 is doing?

It creates an entry in the color preferences wiki:/Help/Preferences/ColorPreference, so users of the style can easily adjust the color themself if needed. We use this for all colors in source:/trunk/resources/styles/standard/elemstyles.mapcss​
