[OpenLayers-Users] Openlayers and Mapnik loading problem

Fri Nov 2 08:31:05 PDT 2012

it seems, that the url is hardcoded in 
OpenLayers.Layer.OSM.Mapnik.initialize
and not changeable by the constructor.

you have to overwrite OpenLayers.Layer.OSM.Mapnik to provide your url.

Betreff: [OpenLayers-Users] Openlayers and Mapnik loading problem

I'm running my own Openstreetmap server with Mapnik installed.
I tried a simple example but the tiles are not loaded.
The online version works (without the Mapnik part and the url's)
I can load a tile from my server e.g.
http://xxx.xxx.xxx.xxx/osm_tiles/18/137213/91823.png

Please provide me a working sample. (I'm stuck for days)

My code;

<!DOCTYPE HTML>

<html>

<head>

<title>OpenLayers Simplest Example</title>

</head>

<body>

<div id="Map" style="height:600px"></div>

<script src="OpenLayers.js"></script>

<script>

    var lat            = 47.35387;

    var lon            = 8.43609;

    var zoom           = 18;

    var fromProjection = new OpenLayers.Projection("EPSG:4326");   //
Transform from WGS 1984

    var toProjection   = new OpenLayers.Projection("EPSG:900913"); // to
Spherical Mercator Projection

    var position       = new OpenLayers.LonLat(lon, lat).transform(
fromProjection, toProjection);

	var url =   ["http://xxx.xxx.xxx.xxx/osm_tiles/${z}/${x}/${y}.png", 

   "http://xxx.xxx.xxx.xxx/osm_tiles/${z}/${x}/${y}.png", 

   "http://xxx.xxx.xxx.xxx/osm_tiles/${z}/${x}/${y}.png"];

    map = new OpenLayers.Map("Map");

    var mapnik         = new OpenLayers.Layer.OSM.Mapnik("Mapnik", url);

    map.addLayer(mapnik);

    var markers = new OpenLayers.Layer.Markers( "Markers" );

    map.addLayer(markers);

    markers.addMarker(new OpenLayers.Marker(position));

    map.setCenter(position, zoom);

</script>

</body>
