OpenLayers 10c unitsがddとmeterのレイヤ

続いて、WMSサーバの設定をします。
マップの投影を元にもどします。
それから、WEB オブジェクトの METADATA と railroad と public_facilities レイヤ（LAYER）の METADATA を次のようにします。

Eclipse を起動して wms_meters.html を開き、次のように layer3 を追加します。

---
<script type="text/javascript">
    var map, layer1, layer2, layre3;
---
        layer3 = new OpenLayers.Layer.WMS( "RailRoad mlit WMS",
                "http://localhost/cgi-bin/mapserv?",
   {
     map: '/home/user/mapfile/kanagawa_mlit_pgis.map',
     layers: 'railroad',
     transparent: true,
     format: 'image/png'
   },
   {
     projection: 'EPSG:4612'
   }
  );

       map.addLayer(layer3);
       map.addLayers([layer1, layer2]);
       map.addControl(new OpenLayers.Control.LayerSwitcher());
       map.zoomToMaxExtent();
    }
</script>
