I want to overlay some data whose projection is WGS-84 on Google map layer in OpenLayers. But I just can't make them in the right place. I did as follows:
map = new OpenLayers.Map('map', { numZoomLevels: 20, projection: new OpenLayers.Projection("EPSG:900913"), displayProjection: new OpenLayers.Projection("EPSG: 4326") });googlelayer = new OpenLayers.Layer.Google("Google street", {sphericalMercator: true});map.addLayer(googlelayer);veclayer = new OpenLayers.Layer.Vector("vector", { projection: map.displayProjection };var geojson_format = new OpenLayers.Format.GeoJSON();veclayer.addFeatures(geojson_format.read(jsonData));Though I have assigned veclayer in 4326 projection, but it is still interpreted as 900913, and the display coordination system is also 900913, though I set displayProjection to 4326. What mistake do I make?
