在英國彈道勘測OpenSpace地圖上添加地圖疊加

Question

有沒有人有代碼示例如何將圖像疊加添加到Ordnance Survey OpenSpace地圖？

The documentation是不完全的綜合:)

謝謝！

開敞空間使用openlayers，這是非常強大的，有據可查的

下面的代碼從樣品那兒剽竊

<script type="text/javascript"> 
    var map; 
    function init(){ 
     map = new OpenLayers.Map('map'); 

     var options = {numZoomLevels: 3}; 

     var graphic = new OpenLayers.Layer.Image(
      'City Lights', 
      'http://earthtrends.wri.org/images/maps/4_m_citylights_lg.gif', 
      new OpenLayers.Bounds(-180, -88.759, 180, 88.759), 
      new OpenLayers.Size(580, 288), 
      options 
     ); 

     graphic.events.on({ 
      loadstart: function() { 
       OpenLayers.Console.log("loadstart"); 
      }, 
      loadend: function() { 
       OpenLayers.Console.log("loadend"); 
      } 
     }); 

     var jpl_wms = new OpenLayers.Layer.WMS("NASA Global Mosaic", 
      "http://t1.hypercube.telascience.org/cgi-bin/landsat7", 
      {layers: "landsat7"}, options); 

     map.addLayers([graphic, jpl_wms]); 
     map.addControl(new OpenLayers.Control.LayerSwitcher()); 
     map.zoomToMaxExtent(); 
    } 
</script>
