[mapserver-users] cannot change coordinate system when using MapCache to serve to ArcGIS clients

Hi Mark,

Is your WMS service advertising "county coordinates" as a supported CRS?


If the WMS default CRS is WGS and no other is advertised then (in my limited experience) Arc will only request content in an advertised CRS - so your default of WGS is the only one it will request.

Hello,

For some reason ArcGIS will only consume my MapCache WMS service in GCS_WGS_1984.  This causes the air photos to be reprojected once on the server (County Coordinates-->WGS) and again on the ArcGIS client ( WGS --> County Coordinates).  I would to avoid reprojecting my air photos.  Unfortunately, nothing happens when I open "Change Coordinate System" in ArcMap then select County Coordinates.  Is this an ArcGIS issue, or is there a problem with MapCache?  

Thanks
