[mapserver-users] WMS cascading

[Rahkonen Jukka]

Hi,
 
When you cascade WMS services the LAYER is defining the remote service. The result of using "wms_srs"  "EPSG:23033" in the nasa layer metadata means that your Mapserver is using EPSG:23033 when sending requests to wms.jpl.nasa.gov.  That is not what you want to do.
Use EPSG:4326 at layer level.  The output projections you want to have are described at MAP level WEB - METADATA section, that is the place to insert EPSG:23033.  At least this is how I understand the how-to documents "WMS clients with Mapserver" and "WMS servers with Mapserver".
 
Regards,

	Hello everybody,
	I am trying to serve, with my wms server, a layer coming from NASA WMS. The source projection is 4326 and I need to reproject to 23033; inside the metada I put the  wms_srs  value, but it's not working..I just just a white  image. Any idea?
	
	Thanks 
	Luca
