@Serializable

@SerialName(value = "MultiPolygon")

data class MultiPolygon(val polygons: List<CachedGeometry.Polygon>) : CachedGeometry

A composite of N independent polygons that belong to one feature (GeoJSON MultiPolygon, GPKG MULTIPOLYGON). Consumers fan it out into N renderables that share one properties map.

Functions

envelopeCenter

fun CachedGeometry.envelopeCenter(): Pair<Double, Double>

Envelope-center (longitude, latitude) of this geometry — a deterministic representative point. Used to assign a feature to a single tile (the one containing its center), so a geometry that straddles a tile boundary renders in exactly one tile instead of every tile its envelope touches.
