Hi,<br><br>I want to have a base layer that is made up of three layers, the relevant layer showing depending on what scale we are zoomed in at.<br>Example:<br>var base = [<br>new OpenLayers.Layer.WMS( "map_1", WMS_URL, {layers: 'map_1', format: 'image/png' }),<br>
new OpenLayers.Layer.WMS( "map_2", WMS_URL, {layers: 'map_2',format: 'image/png'},<br>{minScale: 5000,maxScale: 500,units:'degrees'}),<br>new OpenLayers.Layer.WMS( "map_3", WMS_URL, {layers: 'map_3,format: 'image/png'},<br>
{minScale: 500,units:'degrees'})<br>];<br><br>Is there a way i can change the base layer as i zoom in on the map?<br><br>Thanks for your help<br><br>Justin<br>
