rendering of restricted areas

[quantenschaum]

All restricted areas look the same in OSM. There should be different borders (and/or semi-transparent fillings) to make them distinguishable. Most important from my point of view (proposed style):

• no entry (red fill)
• restricted entry areas (yellow fill)
• nature reserves (green line)
• military areas (diagonal stripes fill or military symbol on line)

@malcolmh this one is for you.

My renderer adheres to the basic INT1 rendering.

[quantenschaum]

Sure, this is fine, but it would substantially improve the usability if the graphical representation of areas of different type was a bit more meaningful.

The current appearance of these areas is very basic, even the INT1 has more symbology for restricted areas, especially for nature reserves (green) and no entry areas. Often there are text note in the charts explaining the restriction.

While I worked on the JOSM maprender of seamarks, I tried to include different restriction zones and nature reserves, but since the subcategories of such areas does not fully correspond with the tagging scheme at that time, it was impossible to make it correct.

I havn't looked at this for a very long time, but unless tagging scheme and data completeness is up to par, such rendering is impossible and/or impractical

[quantenschaum]

You probably can't make it 100% correct, but adding more visual information to the map would be useful. The tagging is sufficient IMHO.
seamark:type=restricted_area seamark:restricted_area:restriction
seamark:restricted_area:category
These tags can be used to style the areas as proposed. name and description could also be displayed, as well as presta/perend.

[quantenschaum]

At least a no entry zone should be visually identifiable as such.
