Mapscript Re-Projection on-the-fly

[Delfos, Jacob]

Stefan,
 
Your question is not entirely clear. You can not re-project an
individual layer on-the-fly, because php_mapscript does not re-write the
dataset (hence its projection will always be the same); you CAN however
change the projection of the map (using setProjection, as you did),
which means all layers in the map get re-projected (the dataset remains
unchanged, though). For this, it is required that your layer has a
projection object with the native projection of that layer. This will
cause the layer to be reprojected along with the map. Is this what you
are trying to do? 
 
You *may* have to save your mapfile, or your session, in order for it to
take effect, depending on your setup.
 
regards,
 
Jacob

	Hey, 

	I can't imagine that such a question stays unanswered in the
mapserver community...

	I meanwhile added a:

	$map -> setProjection("init=epsg:26711");

	to my code, but nothing happens - meaning: no error message but
no reprojection either.

	Can anyone help me out?

	Thanks in advance.

	Stefan

		I couldn't find any precise information about how to
re-project layers on-the-fly via PHP Mapscript. Here and there (via
MailingList and Google) bits and pieces, but altogether it didn't help
me a lot. Though I would have said that this is a basic question. But
perhaps too basic, so everbody finds out by himself?
		
		
		So, can anyone let me know - giving a coding example -
how to re-project a mapfile on-the-fly from for example Lat/Long (global
view) to Lambert or Robin? 
		
		
		Thanks a lot for your help!
