<p class="MsoNormal"><span lang="EN-US">I have a small GRIB file whose coordinate system is GRIB-specific, and it spans the whole world, from longitude 0 to 360. I would like to read this raster from an EPSG:4326 perspective, so I’m using gdalwarp to warp it
to a VRT :<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When I inspect the VRT using GDAL 2.4.0 (the one shipped with QGIS 3.4) I notice that the geotransform is correct. When imported in QGIS, it correctly spans the world from longitude -180 to 180.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">However, the same VRT generated with GDAL 2.3.0 gives a completely different geotransform. Actually it seems that the original geotransform was not modified at all, and I cannot correctly import it in QGIS, since it spans
from 0 to 360, and thus is not aligned properly with other layers in the EPSG:4326 SRS (which span from -180 to 180)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Were there any modification to gdalwarp from 2.3.0 to 2.4.0 ? different default options ?<o:p></o:p></span></p>
