Transformation between coordinates incorrect

Hi,

I have data stored in EPSG:27700 which I am displaying in M.App Enterprise Apps (Desktop, Browser) against OpenStreetMap so I am either creating a vectorset of the data in EPSG:3857 or specifying a EPSG of 3857 when creating a Map View.

 

The data is not transformed correctly when compared with the same transformation run through GeoMedia WebMap and displayed in Geospatial Portal against OpenStreetMap. See screenshots below. Source data is the same, Oracle table with geometries stored in EPSG:27700.

 

Desktop App - Shift shown with red arrow. Boundary of polygon should align with street centre.

Geospatial Portal - Showing correct alignment of data.

Thanks,

Re: Transformation between coordinates incorrect

Hi has anyone seen any transformation issues with M.App Enterprise?

Any response on how this issue should be handled by the Hexagon Geospatial support?
