TileJSON¶

A vector, raster or raster-dem source can point at a TileJSON 3.0.0 document with its url property. MapLibre extends TileJSON with the keys below. A value set on the source in the style takes precedence over the same key in the TileJSON.

emptyResponse¶

vector, raster, raster-dem¶

Optional enum. Possible values: blank, missing. Defaults to "blank".

Experimental. What an empty tile response (HTTP 204, or no tile data from an archive such as PMTiles) means in this tileset.

• blank: The tile is in the tileset and has nothing at that place.
• missing: The tileset has no tile there at that zoom level, and a renderer may use a tile from another zoom level in its place.

encoding¶

vector¶

Optional enum. Possible values: mvt, mlt. Defaults to "mvt".

The encoding used by this source. Mapbox Vector Tiles encoding is used by default.

• mvt: Mapbox Vector Tiles. See http://github.com/mapbox/vector-tile-spec for more info.
• mlt: MapLibre Vector Tiles. See https://github.com/maplibre/maplibre-tile-spec for more info.

raster-dem¶

Optional enum. Possible values: terrarium, mapbox, custom. Defaults to "mapbox".

The encoding used by this source. Mapbox Terrain RGB is used by default.

• terrarium: Terrarium format PNG tiles. See https://aws.amazon.com/es/public-datasets/terrain/ for more info.
• mapbox: Mapbox Terrain RGB tiles. See https://www.mapbox.com/help/access-elevation-data/#mapbox-terrain-rgb for more info.
• custom: Decodes tiles using the redFactor, blueFactor, greenFactor, baseShift parameters.

tileSize¶

raster, raster-dem¶

Optional number. Units in pixels. Defaults to 512.

The minimum visual size to display tiles for this source.
