Vector Tiles

You can specify where to load MVTs (which sometimes have .pbf extension) by creating a TileSet object with template parameters (for example {z} which will be replaced with the zoom level).

MapMetrics has a repo with some example vector tiles with the OpenMapTiles schema around Innsbruck, Austria. In the example we load these MVTs and create a line layer for the road network.

val tileset = TileSet(
    "openmaptiles",
    "https://demotiles.mapmetrics.org/tiles-omt/{z}/{x}/{y}.pbf"
)
val openmaptiles = VectorSource("openmaptiles", tileset)
style.addSource(openmaptiles)
val roadLayer = LineLayer("road", "openmaptiles").apply {
    setSourceLayer("transportation")
    setProperties(
        lineColor("red"),
        lineWidth(2.0f)
    )
}
