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.
