[mapserver-users] Changing to Layers.WMS from Layers.Mapserver

Fri Jul 17 07:22:04 EDT 2009

Hi,

there are several things wrong here.

'wms_srs' "epsg: 32119 epsg: 4326"

should be (uppercase EPSG for METADATA and no space in between):

'wms_srs' "EPSG:32119 EPSG:4326"

however Mapserver cannot reproject your data if you do not add a
PROJECTION block to your LAYER stating the projection in which your data
resides.

Also, in OpenLayers the syntax is (your map can only be in 1 projection):

{projection: "EPSG:32119"}

Best regards,
Bart
