Hello
Users
I am using mapserver3.5 which is working nicely and
displaying
the multiple layers, labels etc in the browser.
Now I want to add the functionality of layer_select, Pan
, Zoom
etc based on the layer selected by a user. I have written two
files one
map file another template file.But in the browser window the
layers are
not displayed, Also Is it necessary to have a raster image on the
background when i use layer_select , pan , zoom etc. Even no
error
message is given in the browser.you can assume that the path names
are correct. If anyone read this mail plz just tell me what is the
wrong with it?and how to to do that by plain mapserv.exe or
mapserv. Also is it necessary to have a mapscript for this type of
example. I am generating the maps using the tutorials provided in
the http://terrasip.gis.umn.edu/tutorial
My map file is like:-(BASED ON THE TUTORIAL PROVIDED IN THE ABOVE
URL)
