[OpenLayers-Users] Adding a Mapserv Layer

Sat Nov 17 14:43:38 EST 2007

Just would like to add that I changed the code following some more tutorials
I found / examples thanks to Chris, and this is the new code :

<html>
<head>
<title>OpenLayers Example</title>
<script src="http://yancho.no-ip.org/~yancho/OpenLayers.js"></script>

<script defer="defer" type="text/javascript">
//var lon = 164;
//var lat = 162;
var map, layer;

function init(){
var options =
{
maxExtent: new OpenLayers.Bounds(625102.34974933861,215593.742071 ,
656343.383138 ,239014.742071),
maxResolution: 302051/1024,
zoom: 0,
projection: "EPSF:4326",
//'controls': [],
units: "m",
numZoomLevels: 12
};
map = new OpenLayers.Map("map", options);
//map.addControl(new OpenLayers.Control.MousePosition());
map.addControl(new OpenLayers.Control.LayerSwitcher());

layer = new OpenLayers.Layer.MapServer( "Streets Layer",
"
http://yancho.no-ip.org/~yancho/cgi-bin/mapserv?map=\\home\\yancho\\public_html\\nc\\sample.map&",
{layers : 'streets'}, {gutter: 15});
map.addLayer(layer);

//map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
map.addControl( new OpenLayers.Control.LayerSwitcher() );
}

</script>
</head>
<body onload="init()">
<div style="width:800px;height:600px" id="map"></div>

</html>

Pastebin : http://pastebin.com/f50f62c3f

The problem is that when I load the page, there is just the controls, and
the map is not loading. There are no JavaScript errors and I think its just
a problem of the loading of the map.

Link to page : http://yancho.no-ip.org/~yancho/openl.html

Link to how I load the map on mapserv :
http://yancho.no-ip.org/~yancho/cgi-bin/mapserv?map=%2Fhome%2Fyancho%2Fpublic_html%2Fnc%2Fsample.map&imgext=637373.285472+230666.856430+647786.963271+238473.856432&imgxy=200.0+150.0&zoom=0&layer=hospitals&layer=streets&layer=firestations&layer=majorroads&layer=railroads&mode=browse&img.x=164&img.y=62

Any help will be much appreciated. Thanks

Regards
