OsmBuilding

data class OsmBuilding(val id: String, val outerRing: List<Position>, val innerRings: List<List<Position>> = emptyList(), val height: Double, val minHeight: Double = 0.0, val name: String? = null, val tags: Map<String, String> = emptyMap())

One OSM building feature, normalized to a simple extrusion model: an outer ring (and optional holes), with height meters above minHeight.

Constructors

constructor(id: String, outerRing: List<Position>, innerRings: List<List<Position>> = emptyList(), height: Double, minHeight: Double = 0.0, name: String? = null, tags: Map<String, String> = emptyMap())

Properties

val height: Double

Top of the building, in meters above terrain.

Source identifier (e.g. OSM way/relation id, prefixed with type).

val innerRings: List<List<Position>>

Optional inner rings (holes) in the same coordinate convention as outerRing.

val minHeight: Double

Base of the building, in meters above terrain (non-zero for upper-floor extrusions like a tower built on top of a podium).

val name: String?

Optional display name from name tag.

val outerRing: List<Position>

Closed outer polygon ring. The list MAY repeat the first point at the end.

val tags: Map<String, String>

Original OSM tag bag for downstream styling (color, roof, etc.).
