I have a serve a number of wms Layers with ArcGIS Server (AGS) with the following coordinate system support - EPSG:25832, EPSG:31467, EPSG:4326 and CRS:84. As far as I can tell, AGS only supports 2 coordinate systems in the GetCapabilities document. Is this correct? Do I have another way to server wms layers in multiple Coordinate systems.
By default, only two coordinate systems are enabled. You'll need to log on to the server and edit a .cfg file to enable more coordinate systems. From the ArcGIS Resource Center:
Configuring the ListSupportedCRS parameter
The ListSupportedCRS parameter can be used to add additional spatial reference systems (such as EPSG:4267) to WMS services. By default, WMS services only list two spatial reference systems; EPSG:4326 (or CSR:84 for WMS 1.3.0) and the spatial reference of the map service that WMS is enabled on. By using the ListSupportedCRS parameter, you can advertise more reprojection options to WMS clients by specifying additional spatial references.
The ListSupportedCRS parameter is not listed as a service property when configuring WMS services in ArcCatalog or ArcGIS Server Manager. To add the ListSupportedCRS parameter to a WMS service, you must edit the service configuration file (.cfg) of the map service on which you enabled WMS.
