<div>Hello fellow chameleon users.</div> <div> </div> <div>I would to seek your help regarding turning on and off layers.<BR><BR><SPAN class=quoted1>In my map, I am aiming to have two views: a graphical view </SPAN><SPAN class=quoted1> and an aerial view. How do I</SPAN><SPAN class=quoted1> make it such that a user will only have to click a link in </SPAN><SPAN class=quoted1> the page and will transform </SPAN><SPAN class=quoted1> the view from a graphical one (shape files) to an aerial one </SPAN><SPAN class=quoted1> (aerial pphotograph). I have</SPAN><SPAN class=quoted1> seen a campus map of MIT (<A class=fixed href="http://mail.up.edu.ph/horde/util/go.php?url=http%3A%2F%2Fwhereis.mit.edu%2Fmap-jpg&Horde=37be496d6af69b5651d122cd40b96a90" target=_blank>http://whereis.mit.edu/map-jpg</A>) </SPAN><BR><SPAN class=quoted1> that employs this kind of</SPAN><SPAN class=quoted1> method.</SPAN><BR><SPAN
class=quoted1> </SPAN><BR><SPAN class=quoted1> I believe the principle here is that I only have to turn off </SPAN><SPAN class=quoted1> the graphical layers and then</SPAN><BR><SPAN class=quoted1>turn on the aerial photograph layer when the view is </SPAN><SPAN class=quoted1> switched... But how will I do it? How</SPAN><SPAN class=quoted1> do I make a link in my html file that will turn on the photo </SPAN><SPAN class=quoted1> layer and turn off the</SPAN><BR><SPAN class=quoted1>others, and vice versa?</SPAN><BR><SPAN class=quoted1> </SPAN><BR><SPAN class=quoted1> I tried having two sets of map files.. one for shape file </SPAN><SPAN class=quoted1> layers and the other for the</SPAN><BR><SPAN class=quoted1>aerial photograph.. However, I think it was not useful </SPAN><SPAN class=quoted1> because when the view is switched,</SPAN><SPAN class=quoted1> the scale at which the map is displayed before the switch was </SPAN><SPAN
class=quoted1> not preserved.</SPAN><BR><SPAN class=quoted1> </SPAN><BR><SPAN class=quoted1>I consulted Jacob Delfos about this and he said the solution is though the use of javascripts. But I am nowhere at javascript.</SPAN></div> <div><SPAN class=quoted1></SPAN> </div> <div><SPAN class=quoted1>Please help.</SPAN></div> <div><SPAN class=quoted1> </div> <div><SPAN class=quoted1>By the way I'm using MS4W.</SPAN></div> <div></SPAN><SPAN class=quoted1></SPAN> </div> <div><SPAN class=quoted1>Thanks in advance.</SPAN></div> <div><SPAN class=quoted1></SPAN> </div> <div><BR><SPAN class=quoted1> </SPAN><BR><SPAN class=quoted1> </SPAN><BR><SPAN class=quoted1> Regards,</SPAN><BR><SPAN class=quoted1> </SPAN><BR><SPAN class=quoted1> </SPAN><BR><SPAN class=quoted1> Jojin</SPAN><BR></div><p>
