<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">When I add a layer with OSGB36 (epsg:27700) projection to a project in QGS84 (epsg:4326), I am given an option to select the coordinate transformation to use. There are multiple options:
<a href="https://epsg.io/27700">https://epsg.io/27700</a>. The best includes a custom correction grid, OSTN15_NTv2.<br>
<br>
Once the layer has been added, is there a way to see which transformation was used?<br>
<br>
It isn’t mentioned in the Coordinate Reference System section of the layer properties. The definition of OSGB36 in the project projection selection dialog doesn’t mention the custom transformation grid. Is there a way to see it in the project XML?<br>
