AW: [OpenLayers-Users] Difference between WMS and WFS on the sameGeoserver Layer

[Arnd Wippermann]

You should change your map options, so that they meet the choosen
projection:

var options = {
	controls: [],
	projection: new OpenLayers.Projection("EPSG:4326"),
	displayProjection: new OpenLayers.Projection("EPSG:4326"),
	units: 'dd',
	numZoomLevels: 16,
	maxResolution: 1.40625,
	maxExtent: new OpenLayers.Bounds(-180,-90,180,90)
};

Perhaps that solves it.

Betreff: [OpenLayers-Users] Difference between WMS and WFS on the
sameGeoserver Layer

Hi there,

the point features in these two layers differ for about 300 meters.
They use the same Geoserver (2.1.1) layer. Native SRS  is EPSG:900913,
Declared SRS is EPSG:4236. The WFS is correct. What's wrong with the WMS? 

var options = {
	controls: [],
	projection: new OpenLayers.Projection("EPSG:4326"),
	displayProjection: new OpenLayers.Projection("EPSG:4326"),
	units: 'm',
	numZoomLevels: 18,
	maxResolution: 156543.0339,
	maxExtent: new OpenLayers.Bounds(-20037508, -20037508,
20037508,20037508.34)
};

var flaglayer = new OpenLayers.Layer.WMS("WMS",
	"http://domain/geoserver/basic/wms",
	{layers:"basic:gis_elemente",transparent:true});
map.addLayers([flaglayer ]);    

var prueflayer =new OpenLayers.Layer.Vector("Vector", {
	strategies: [new OpenLayers.Strategy.BBOX()],
	protocol: new OpenLayers.Protocol.WFS({
		url:  "http://domain/geoserver/wfs",
		featureType: "gis_elemente",
		featureNS: "http://domain/geoserver/basic",

	})
				
});
map.addLayers([prueflayer]); 

Thanks for answering.

Gabriele
