[OpenLayers-Users] Set extent for mapserver's layer with gmap(Chen kuja)

[Arnd Wippermann]

Hi Chen,
 
try this
var gsat = new OpenLayers.Layer.Google("Google Satellite", {type:
G_SATELLITE_MAP, 'sphericalMercator': true});        
instead of your line
var gsat = new OpenLayers.Layer.Google("Google Satellite", {type:
G_SATELLITE_MAP, },{'sphericalMercator': true});        



Mit freundlichen Grüssen

Thanks for the better code. But things getting weird here. my mapfile
displayed pretty well as epsg900913(i can see the different from epsg 4326)
under the "map.setCenter(new
OpenLayers.LonLat(12728934.108387556,3564373.2839840306), 15);" -- as it
should be, it's 900913. However, as for the gmap, it seems require "
map.setCenter(new OpenLayers.LonLat( 114.350503, 30.475874), 10);" --- the
normal lon&lat, not google's own coordinate system. It dizzied my for hours.
with this, it is impossible for me to integrate those two map.

I can't find much example like local mapserver file and gmap, so I wonder in
which steps i did wrong?
here is the code
  <script type="text/javascript">
             var map, layer;
           function init() {
 
    var options = {
        projection        : "EPSG:900913",
        maxExtent         : new OpenLayers.Bounds(-120037508.34,
-120037508.34, 120037508.34, 120037508.34),
     //   maxExtent         : new OpenLayers.Bounds(12727216.047735045,
3563238.963082024, 12731224.662598498, 3566021.113954254),
        maxResolution     : 156543.0339,
        maxZoomLevel      : 35,
        numZoomLevels     : 35,
        units             : "m",
        controls          : []
        };
            map = new OpenLayers.Map( 'map',options);
           //     var base = new OpenLayers.Layer.MapServer( "Base Layer",
"http://127.1/cgi-bin/mapserv.exe?",
             
            var gsat = new OpenLayers.Layer.Google("Google Satellite",
{type: G_SATELLITE_MAP, },{'sphericalMercator': true});        
            
          //  var gsat = new OpenLayers.Layer.Google("Google
Satellite",{type: G_SATELLITE_MAP, });
           map.addLayers([gsat]);
          //  map.addLayers([gsat]);
            map.addControl(new OpenLayers.Control.PanZoomBar(), new
OpenLayers.Pixel(2,30));
    map.addControl(new OpenLayers.Control.LayerSwitcher());
    map.addControl(new OpenLayers.Control.MouseDefaults());
    map.addControl(new
OpenLayers.Control.MousePosition({element:document.getElementById("rota"),
numdigits:3}));
      //  map.setCenter(new
OpenLayers.LonLat(12728934.108387556,3564373.2839840306), 15);
   map.setCenter(new OpenLayers.LonLat( 114.350503, 30.475874), 10);
       };
   
    </script>

ps. Last afternoon, a earthquake stroke South Sichuan, China. It's about
1000km away from my university, but still I can felt the terrible shaking
for 1 minute. It even spread to my home in Shanghai. I spent 3 hours, tyring
to call my friends in Chengdu&Chongqing. Luckily, they are all alright. But
I know ,  10 thousands had died, more still buried. GOD BLESS THEM
