GPXTileServer

enum GPXTileServer : Int

Configuration for supported tile servers.

Maps displayed in the application are sets of small square images caled tiles. There are different servers that provide these tiles.

A tile server is defined by an internal id (for instance .openStreetMap), a name string for displaying on the interface and a URL template.

  • CartoDB tile server

    Declaration

    Swift

    case cartoDB

  • CartoDB tile server (2x tiles)

    Declaration

    case cartoDBRetina

  • OpenTopoMap tile server

    Declaration

    Swift

  • String that describes the selected tile server.

    Declaration

    var name: String { get }

  • URL template of current tile server (it is of the form http://{s}.map.tile.server/{z}/{x}/{y}.png

    Declaration

    Swift

    var templateUrl: String { get }

  • In the templateUrl the {s} means subdomain, typically the subdomains available are a,b and c Check the subdomains available for your server.

    Set an empty array ([]) in case you don’t use {s} in your templateUrl.

    Subdomains is useful to distribute the tile request download among the diferent servers and displaying them faster as result.

    Declaration

    Swift

    var subdomains: [String] { get }

  • Maximum zoom level the tile server supports Tile servers provide files till a certain level of zoom that ranges from 0 to maximumZ. If map zooms more than the limit level, tiles won’t be requested.

    Typically the value is around 19,20 or 21.

    This limits the tiles requested based on current zoom level. No tiles will be requested for zooms levels lower that this.
