Hi all
I'm trying to start a map using the following function. I want to open using
some prescribed bounds that are in long, lat (ESPG:4326) but i'm using
google maps for the baselayer so the projection is EPSG:900913. I thought
the following code would work ok but it just loads a blank map.
Regards
Matt
function init(){
// Map is in mercator this time, so over-ride the default
// options that assume lat/lon.
var options = {
projection: new OpenLayers.Projection("EPSG:900913"),
displayProjection: new OpenLayers.Projection("EPSG:4326"),
units: "m",
numZoomLevels: 20,
maxResolution: 156543.0339,
};
var extent = new OpenLayers.Bounds(-7.423, 50.102,
-0.383, 60.988).transform(
new OpenLayers.Projection("EPSG:4326),
new OpenLayers.Projection("EPSG:900913)
);
// Create the map object
map = new OpenLayers.Map('map', options);
// create Google Maps layer
var gmap = new OpenLayers.Layer.Google(
"Google Streets", // the default
{'sphericalMercator': true, numZoomLevels: 20}
);
// create Google Satellite layer
var gsat = new OpenLayers.Layer.Google(
"Google Satellite",
{type: G_SATELLITE_MAP, 'sphericalMercator': true, numZoomLevels: 20}
);
// create WMS Atrina layer
var wmslayer = new OpenLayers.Layer.WMS(
"Atrina",
"http://localhost:8080/geoserver/wms";,
{'layers': 'DASSH:Atrina', 'format':'image/png',
'transparent':'true'},
{'opacity': 1.0, 'isBaseLayer': false, 'visibility': true}
);
map.addLayers([gmap, gsat, wmslayer]);
map.addControl(new OpenLayers.Control.LayerSwitcher());
// Coordinate display at bottom of map
map.addControl(new OpenLayers.Control.MousePosition());
map.setCenter(extent, 5);
}
