How can I fix the overlaid of the Geotiff Ordnance Survey maps with the XYZ Google Maps?
I know, that Google uses the EPSG:4326 WGS84 ordinance system, whereas Ordnance Survey uses OSGB British National Grid EPSG 27700. I know also where to change the CRS, but if I change the CRS in my project reference it still comes with the wrong overlay. Unfortunately, the difference is too big, over 2m.
I have an option to transform my coordinates, but I don't know which one should be correct.
Transforming Google Maps overlay to fit Ordnance Survey projection shows pretty much the opposite of what I am trying to do.
