I have a really basic question which I can't wrap my head around.

I have a GeoTIFF of the world and a shapefile containing the oceans. The problem is that the GeoTIFF is centered at -180° longitude while the shapefile is centered at 0° longitude.

Looking at their SRS info using gdalsrsinfo it looks like they use exactly the same basic WGS84 projection.

How can I get them to overlap?

  • The GeoTIFF seems centered at +180 longitude (instead of -180), its coordinates seems to go from 0 to +360.

  • Please decide whether you wish to ask about QGIS or GDAL in this particular question. You can always ask about the other in a separate question.

  • Ah sorry, didn't know this is a problem. Thanks for pointing it out.

  • @GabrielDeLuca so it's a coordinates issue and not a projection issue? Is there a gdal command to fix that?

  • @Flavio, The shapes overlaps, therefore seems to be well projected. I don't know if can be fixed with one command. But "copy the raster with a -360 shift in x coordinate, merge both rasters and clip within the extents" process, should be posible.
