Openlayers设置ESPG900913作为影射算法
Geoserver默认的地图影射方式是EPSG:4326,但是对于常用的WebGIS来说,常用的影射方式是EPSG:900913,下边的代码用来设置openlayers,通知geoserver使用新的映射算法
var options = {
projection: new OpenLayers.Projection("EPSG:900913"),
maxResolution:156543.0339,
maxExtent: new OpenLayers.Bounds(-20037508.3427892,-20037508.3427892,20037508.3427892,20037508.3427892),
units: "m",
numZoomLevels: 17,
displayProjection: new OpenLayers.Projection("EPSG:4326"),
controls: []
}
var map = new OpenLayers.Map('map', options);
