<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> I am using OpenLayers to display a map that has about
20 different layers. Currently, I request all 20 layers during the ‘init’
function and display them as baselayer. I read the API and saw there are some “zoomBar*”
event functions that get called when various actions related to zooming take
place, but I wasn’t sure how to overload them, or if that was the proper
thing to do. Is there a “zoom Level Changed” event for a map where
I could define a function that updates the map to have different base layers
that vary according to the zoom level?<o:p></o:p></span></font></p>
