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

[Mark Volz]

Brent.

Here is the SRS and Server information.

SRS: 103744, 900913, 103749, 26915, 4326, 3857.   103749 is Lyon county coordinates and it is used by ESRI.

If this is the correct way...  GetCapabilities Document: http://geomoose.lyonco.org/mapcache/cgi-bin/mapserv?map=LyonAirPhotos&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities

Server:  http://geomoose.lyonco.org/mapcache?

So what SRS's are advertised in the MapCache capabilities document?

Is the URL for that publicly available?

Brent and Bobb.

I am using EPSG 103749, which is ESRI's custom version for our county coordinates.  I added those coordinates into MapServer and MapCache.  MapCache advertises the county coordinates, UTM 15, Google, and apparently GCS_WGS_1984.
-I tried using UTM 15 which is a more common projection.  That did not work.
-I should also mention that I can connect directly from an ArcGIS client to MapServer using county coordinates.  The only coordinate system that MapServer advertises is in our county coordinates.

Thanks
