[mapserver-dev] Problem with zooming

Sat Aug 27 10:10:14 EDT 2011

Hello, I am from Sri Lanka and currently developing web based GIS .I am
using OpenLayers for map viewing purpose . I have been facing a problem when
zooming the map. When i zoom the map using control in OpenLayer API , map is
not zoom but giving several images of the land. Can anyone give me a
suggestion to fix this problem ?

*OpenLayer code*

<!DOCTYPE html>
<html lang='en'>
<head>
    <meta charset='utf-8' />
    <title>Map of New Airports in Sri Lanka</title>
    <script type='text/javascript' src='OpenLayers.js'></script>
    <script type='text/javascript'>

    var map;

    function init() {
    map = new OpenLayers.Map('map_element', {});

    var wms_layer_airports = new OpenLayers.Layer.WMS (
     'New Airports in Sri Lanka',
     '
http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/airports.map&layer=boundary&layer=new_airports_in_srilanka&mode=map
',
     {layers:'new_airports_in_srilanka'},
     {isBaseLayer:false}

     );

     var wms_layer_boun = new OpenLayers.Layer.WMS(
    'Boundary layer',
    '
http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/mapfilemangrooves25label1.map&layer=boundary&mode=map
',
    {layers:'boundary'},
    {isBaseLayer:true}

    );

         map.addLayers([wms_layer_airports,wms_layer_boun]);
         map.addControl(new OpenLayers.Control.LayerSwitcher({}));

        if(!map.getCenter()){
            map.zoomToMaxExtent();
        }
    }

    </script>
</head>

<body onload='init();'>
    <div id='map_element' style='width: 500px; height: 500px;'>
    </div>
</body>
</html>
