walls_and_buildings

[object Object]

Special builtin layer providing all walls and buildings. This layer is useful in presets for objects which can be placed against walls (e.g. AEDs, postboxes, entrances, addresses, surveillance cameras, …). This layer is invisible by default and not toggleable by the user.

• This layer is shown at zoomlevel 18 and higher
• This layer is not visible by default and must be enabled in the filter by the user.
• This layer is not visible by default and the visibility cannot be toggled, effectively resulting in a fully hidden layer. This can be useful, e.g. to calculate some metatags. If you want to render this layer (e.g. for debugging), enable it by setting the URL-parameter layer-=true
• Not visible in the layer selection by default. If you want to make this layer toggable, override name
• Not rendered on the map by default. If you want to rendering this on the map, override mapRenderings
• This layer will automatically load entrance into the layout as it depends on it: a calculated tag loads features from this layer (calculatedTag[0] which calculates the value for _entrance_properties)
• This layer is needed as dependency for layer advertising
• This layer is needed as dependency for layer artwork
• This layer is needed as dependency for layer clock
• This layer is needed as dependency for layer defibrillator
• This layer is needed as dependency for layer entrance
• This layer is needed as dependency for layer surveillance_camera
• This layer is needed as dependency for layer facadegardens
• This layer is needed as dependency for layer ghostsigns
• This layer is needed as dependency for layer parking_spaces_disabled
