[OpenLayers-Users] Why won't this map re-center?

[Andreas Hocevar]

Hi,

you have to pass the coordinates in the map's SRS (EPSG:900913 for the
OSM layer) to setCenter, and you can combine setCenter with zoomTo. So
the following will center your map at and zoom to zoom level 2:

var wgs84 = new OpenLayers.Projection("EPSG:4326");
var mercator = new OpenLayers.Projection("EPSG:900913");
map.setCenter(
    new OpenLayers.LonLat(-98.4375,39.774769).transform(wgs84, mercator),
    2
);

Andreas.
