[OpenLayers-Users] WFS, what EPSG use???

Thu Oct 29 11:32:53 EDT 2009

Hi,

looking at 
http://www.aplicanet.gob.mx:8080/geoserver/wfs?version=1.0.0&request=GetFeature&typename=sde:DTYT.SSC_RUTAS_2009&maxfeatures=10 
I see that your native SRS is EPSG:32614.

Also, it seems you want your base layer in EPSG:900913. But your 
setCenter is in EPSG:4326, and your map also is.

Why don't you use Layer.Vector with a BBOX strategy and a WFS protocol? 
Layer.WFS is a bit old school. Look at 
http://www.openlayers.org/dev/examples/wfs-protocol.html for an example.

Your config should look like this:

    var layer = new OpenLayers.Layer.Vector("WFS", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url:  "http://www.aplicanet.gob.mx:8080/geoserver/wfs",
            featureType: "DTYT.SSC_RUTAS_2009",
            featureNS: "http://geoserver.sf.net",
            version: "1.1.0",
            srsName: "EPSG:4326"
        })
    });

Regards,
Andreas.
