[mapserver-users] Trouble when serving mapcache WMTS to ArcMap clients - custom

[Passmore, James H.]

I see you have in the GetCapabilities file <ows:SupportedCRS>urn:ogc:def:crs:EPSG:6.3:103744</ows:SupportedCRS>

That's surely wrong, as 103744 is not a valid EPSG code, but one defined by ESRI (https://github.com/Esri/projection-engine-db-doc/blob/master/proj4/esri)

I'm not sure if it would work if you stated it like  urn:ogc:def:crs:ESRI::103744 or just ESRI::103744, but it's possible that ArcMap is trying to do an EPSG lookup, failing and reverting to WGS84

Subject: [mapserver-users] Trouble when serving mapcache WMTS to
ArcMap clients - custom county projection for Minnesota?

Hello,

I am having trouble serving a Mapserver / Mapcache WMTS service to ArcMAP clients when using my counties projection which is 103749 for Lyon County, MN.  At most tile zoom levels the air photo are further South than where they should otherwise be located.  The only exception is that around 1:6000 the image lines up perfectly.  When I connect ArcMAP to the Mapcache Service using WMS the service works fine however ArcGIS wants to consume the service in WGS_84 instead of county projections.

Is there anything I need to do so that my WMTS service works better between MapServer(Mapcache), ArcGIS, and possibly QGIS?

Thank You!
Sincerely,
