We are having some problems loading a WMS layer pushed to Geoserver with NAD27 (EPSG:4267), When it is opened in QGIS, it shows a shift of around 20 m. My doubt here is, what are the parameters QGIS is using to this transformation?
Looking into qgis's srs.db, the prefered transformation is one with the 7 parameters of molodensky transformation, can I assume that that's what it's being used if not asked to the user? How about grids? In Osgeo4w installation seems to be a few grids available in the shared folder including a "conus" file that could be useful for transformation. Could we use it? Thanks!
