layerId
The id for an operational layer in the map. This allows LevelLayerInfo to refer to an operational layer that contains level features. When configuring a floor-aware map manually, as opposed to configuring it in ArcGIS Pro, this value needs to be set with the ID value from the appropriate Layer object, whether a FeatureLayer or SceneLayer.
shortNameField
The field name from the layer that defines the level short name of a feature. The level short name supports floor filtering in floor-aware apps. Some floor-aware apps only display a short name in the floor filter, others may use the longNameField or allow toggling between the two.
verticalOrderField
The field name from the layer that defines the order of display and reference to floors in the Indoor Positioning System. It uses a zero-based ordering system to define the floor order. The ground level of each facility is represented as zero. Positive values represent floors above ground, and negative values represent floors below ground. Values must be continuous and a value in the sequence cannot be skipped.
