OpenLayers. Layer.OSM

This layer allows accessing OpenStreetMap tiles. By default the OpenStreetMap hosted tile.openstreetmap.org Mapnik tileset is used. If you wish to use a different layer instead, you need to provide a different URL to the constructor. Here’s an example for using OpenCycleMap:

new OpenLayers.Layer.OSM("OpenCycleMap",
  ["http://a.tile.opencyclemap.org/cycle/${z}/${x}/${y}.png",
   "http://b.tile.opencyclemap.org/cycle/${z}/${x}/${y}.png",
   "http://c.tile.opencyclemap.org/cycle/${z}/${x}/${y}.png"]);

Summary

OpenLayers. Layer.OSM	This layer allows accessing OpenStreetMap tiles.
Properties
name	{String} The layer name.
url	{String} The tileset URL scheme.
tileOptions	{Object} optional configuration options for OpenLayers.Tile instances created by this Layer.
Constructor
OpenLayers. Layer.OSM

Properties

name

{String} The layer name. Defaults to “OpenStreetMap” if the first argument to the constructor is null or undefined.

url

{String} The tileset URL scheme. Defaults to

http://[a|b|c].tile.openstreetmap.org/${z}/${x}/${y}.png

(the official OSM tileset) if the second argument to the constructor is null or undefined. To use another tileset you can have something like this:

new OpenLayers.Layer.OSM("OpenCycleMap",
  ["http://a.tile.opencyclemap.org/cycle/${z}/${x}/${y}.png",
   "http://b.tile.opencyclemap.org/cycle/${z}/${x}/${y}.png",
   "http://c.tile.opencyclemap.org/cycle/${z}/${x}/${y}.png"]);

tileOptions

{Object} optional configuration options for OpenLayers.Tile instances created by this Layer. Default is

{crossOriginKeyword: 'anonymous'}

When using OSM tilesets other than the default ones, it may be necessary to set this to

{crossOriginKeyword: null}

if the server does not send Access-Control-Allow-Origin headers.

Constructor

OpenLayers. Layer.OSM

Parameters

name	{String} The layer name.
url	{String} The tileset URL scheme.
options	{Object} Configuration options for the layer. Any inherited layer option can be set in this object (e.g. OpenLayers.Layer.Grid.buffer).
