[OpenLayers-Users] Bounding Box and Orthographic projection "AUTO2:42003,1,-75.,0."

Wed Mar 2 13:34:51 EST 2011

Hello, 

I dont really know how I solve it, but I start from scratch following the openlayers test page in geoserver, and this code did the trick:

		var map;
            var untiled;
            function init(){

                format = 'image/png';

                var bounds = new OpenLayers.Bounds(
                    -7800000, -7800000,
                    7800000, 7800000
                );
                var options = {
                    controls: [],
                    maxExtent: bounds,
                    maxResolution: 60937.5,
                    projection: "AUTO2:42003,1,-75.,0.",
                    units: 'm'
                };
                map = new OpenLayers.Map('map', options);

                // setup single tiled layer
                untiled = new OpenLayers.Layer.WMS(
                    "raster", "http://localhost:8080/cgi-bin/mapserv", 
                    {	
			map: '/opt/fgs/www/htdocs/esfericas/data/esfericas.map',
                        width: '660',
                        crs: 'AUTO2:42003,1,-75.,0.',
                        layers: 'mars_orbital',
                        height: '330',
			version: '1.3.0',
                        styles: '',
                        format: format
                    },
                    {singleTile: true, ratio: 1, isbase: true} 
                );

                map.addLayers([untiled,tiled]);
                 map.zoomToExtent(bounds);

}

Dear list,

I am having a bit of troube trying to set the bbox parameter in a wms request.

I want openlayers to request the following url (which works) (image in orthographic projection similar to the ones in http://glmapserver.sourceforge.net/test/layer_test.html)

http://localhost:8080/cgi-bin/mywms?LAYERS=mars_orbital&VERSION=1.3.0&EXCEPTIONS=INIMAGE&SERVICE=WMS&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&CRS=AUTO2%3A42003%2C1%2C-75.%2C0.&BBOX=-7800000.,-7800000.,7800000.,7800000.&WIDTH=512&HEIGHT=256

But all I can get is this (which does not work)

http://localhost:8080/cgi-bin/mywms?LAYERS=mars_orbital&VERSION=1.3.0&EXCEPTIONS=INIMAGE&SERVICE=WMS&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&CRS=AUTO2%3A42003%2C1%2C-75.%2C0.&BBOX=-360,-180,360,180&WIDTH=512&HEIGHT=256

The only difference is the bbox parameter. Openlayers keeps requesting BBOX=-360,-180,360,180 when I need BBOX=-7800000.,-7800000.,7800000.,7800000

I dont know how to set the extent, this is what I tried :

        function init(){
            var options = {
                projection: new OpenLayers.Projection("AUTO2:42003,1,-75.,0."),
                units: "m",
                maxExtent: new OpenLayers.Bounds(-7800000,-7800000,7800000,7800000)
            };
            map = new OpenLayers.Map('map',options);
            var ol_wms = new OpenLayers.Layer.WMS(
                "OpenLayers WMS",
                "http://localhost:8080/cgi-bin/mywms",
                {layers: 'mars_orbital',VERSION: "1.3.0"},
                {singleTile: true, ratio: 1});
            map.addLayer(ol_wms);
            map.addControl(new OpenLayers.Control.LayerSwitcher());
            map.zoomToMaxExtent();

Thanks in advance!!
