[mapserver-users] Mapcache WMTS - imagery is offset in ArcGIS when using WMTS services.

Hello,

I noticed that WMTS services are extremely fast when using Mapcache to serve tiles to ArcGIS clients.  However, the imagery appears to be shifted down significantly from the actual location.   I did notice that Mapserver and Mapcache use a 72 DPI while ArcGIS is using a 90.714 DPI.  In addition the image is the correct width and height.  In addition, when I use WMS the imagery appears in the correct location, however it is not as fast as WMTS.

Please let me know if there is a way to get ArcGIS to place imagery in the correct location when using WMTS and Mapcache.

Thanks

Sincerely,
Mark Volz, GISP
