MapServer draws all layers in order in the mapfile from bottom to top - =
that is, each layer in turn is drawn on top of all preceding layers. =
Put your annotation layer as the last layer in the file.

Subject: [Mapserver-users] How to Draw Annotation Layer Last
Hello,
I have searched through the archives w/o much luck on determining what I =
am doing wrong. =20
I am using MapServer v3.5 and am trying to draw an annotation layer so =
it is always the last layer to be drawn and shows on top of all other =
layers. Right now it is always drawn under my other layers and is not =
seen. I also use PHP/Mapscript to create the maps and have tried to =
force this layer to be drawn last, w/o success. Can anyone clue me in =
on the method to ensure this layer is always draw last, either via the =
map file only or via php/mapscript? Below is the map file entry for the =
layer and the php/mapscript snippet.
Thanks!
