Greetings
I'm using GDAL to pre-process a few GRIB files and compare it with
tkdegrib and I realized that GDAL processing GRIBs have a displacement
of a nearly 0,5 pixel SE. I'm using GDAL 1.7.1, released 2010/02/08 . Is
there any fix for this issue/problem?
António,
You could try filing a ticket with the file, and a description of why
you are convinced it is off by half a pixel. Keep in mind that GDAL's
georeferencing model has the origin at the top left corner of the top
left pixel while some raster data/products treats the origin as being at
the center of the top left pixel (or you can think of it as considering
the pixels as point).
Best regards,
