[OpenLayers-Users] how to add a non-base layer?

Thu Mar 5 20:02:45 EST 2009

Hi Melvin

Just include them in the layers parameter with commas between in your WMS call eg:

var topowms = new OpenLayers.Layer.WMS( "Topos",
                          "http://10.64.20.120/cgi-bin/gsswms.exe?",
                          {layers: ['nzislands','nznoaa','nz1mtm','nz250ktm','nz50ktm','linz_orthos'], format: "image/png"},
                          {singleTile: true, minResolution: 1000} );

Cheers,

Robert

hi all,

how do you add an overlay layer to openlayers? i have 7 ESRI shapefiles (POINT) that i want to display. So far i only get examples on google map layers, but i don't see examples on how to add more than 1 non-base layers in a shapefile format. Below is my simple code:

<html>
<head>
<title>OpenLayers Example</title>
<script src="http://openlayers.org/api/OpenLayers.js"></script>
</head>
<body>
<div style="width:100%; height:100%" id="map"></div>
<script defer="defer" type="text/javascript">
var map = new OpenLayers.Map('map');
var wms = new OpenLayers.Layer.WMS( "Background Layer",
"http://localhost/cgi-bin/mapserv.exe", {map: 'C:\ms4w\Skripsi\coba.map'},
{isBaseLayer: true} );
map.addLayer(wms);
map.zoomToMaxExtent();
</script>

</body>
</html>

Cheers,
Melvin
