[Chameleon] Projection and ZoomAllLayer fail

[Delfos, Jacob]

Thio,
 
The projection definition in your layers should not be set to auto, because the source data is only ever in one projection. Just because you shift a map to another zone, for instance, does not cause your source data to change. MapServer (Chameleon) mus know where to re-project the data FROM (not TO). Therefore, IF your source data is in zone 49s, put this in your layers:
 
    PROJECTION
      "init=AUTO:32749"
    END
 
Make sure to find out what projection your source data is in. If in doubt, send us an example coordinate.
 
I suppose you could put the automatic projection in your mapfile. But it may confuse users if they can see coordinates without knowing what they are in. 
 
Best regards,
 
Jacob

	Dear forumers..
	
	
	[Projection fail]
	I'd try to configure my map file with a fixed projection. I use the UTM WGS84 49S for my data, so i decide to use "auto:42001". But those configuration is fail, my browser only shows : 
	
	Warning: [MapServer Error]: msProcessProjection(): No such file or directory in C:\ms4w\apps\chameleon\htdocs\common\wrapper\map_session.php on line 215
