I was able to add a raster layer in GRIB2 format (NCEP global meteorological data). The longitude values range from 0 to 360 degrees. I’m able to view and do calculations on the data with no problem. I also added shaded relief and coastline data from Natural Earth. This data has longitude values from -180 to 180 degrees. So from -180 to 0 degrees I only see the Natural Earth data, from 0 to 180 degrees I see both datasets and from 180 to 360 degrees I only see the GRIB2 data. I want both datasets to be referenced the same with regards to longitude (-180 to 180, 0 to 360 or whatever). It seems like this should be a fairly easy problem to fix by either adding 180 degrees to longitudes from the Natural Earth data or subtracting 180 from the GRIB2 longitudes, but I can’t figure out how to do it.<br class="">
<br class="">
I’m using QGIS version 3.4.1-Madeira. The CRS I’m working in is what QGIS put the GRIB2 data into when I added it: * Generated CRS (+proj=longlat +a=6371229 +b=6371229 +no_defs)<br class="">

Thanks,<br class="">
