Tile json

Source: R/tile_json.R
tile_json.Rd

Intended for use as the data parameter of mvt_layer(). Creates a tile json url from a tileset_id and tile_service. Tile service defaults to getOption("rdeck.tile_service") %||% "mapbox".

The created url will be fetched and parsed with jsonlite::fromJSON().

Usage

tile_json(tileset_id, tile_service = NULL)

Arguments

tileset_id

<string> The tileset_id, may be one of the following

  • a tileset identifier, e.g. "mapbox.mapbox-streets-v8"

  • a tileset identifier.json, e.g. "mapbox.mapbox-streets-v8.json"

  • a url, e.g. "mapbox://mapbox.mapbox-streets-v8", or "https://mytileserver/tileset"

tile_service is unused if a url is supplied.

tile_service

<string> The tile service name, defaults to `getOption("rdeck.tile_service") %||% "mapbox".

Note

Authentication via mapbox_access_token() occurs when tile_service = "mapbox", or tileset_id uses the mapbox scheme (i.e. mapbox://).

Examples

if (FALSE) {
tile_json("mapbox.mapbox-streets-v8", "mapbox")
tile_json("mapbox.mapbox-streets-v8.json", "mapbox")
tile_json("mapbox://mapbox.mapbox-streets-v8")
tile_json("mapbox://mapbox.mapbox-streets-v8.json")
tile_json("https://mytileserver/tileset.json")
tile_json("tileset.json", "https://mytileserver")
}
