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