Dynamic Viewpoint Symbols
Two years ago i showed a new design concept for rendering trees in maps. This used a combination of hand designed components with automatic geometry processing to depict different types of trees of different sizes in a way the symbols naturally overlap in a well readable way when the trees are close to each other.
OSM-Carto has rendered viewpoints with a static point symbol for a long time, but is not taking into account the direction tag. This ensures a good readability of the fairly fine grained symbol design above strongly structured backgrounds – which are common near viewpoints with elements like natural=cliff, barrier=retaining_wall or natural=bare_rock polygons. The main POI ( amenity-points) layer is rendered with the viewpoints being represented by zero opacity placeholder markers, that have a suitable anchor-set parameter to document successful symbol placement.
