Hello
I got a reply to my message stating that " GDAL ignores a flag in the GEOTIF
specification that says whether the coordinates are for the center or the
lower-left of each pixel. "
Is this true? It's exacly what I am obtaining and what Markus Neteler explained
me (about the useage of NN method)
Can anyone confirm me?
Luisa,
Prior to GDAL 1.8 the "PixelIsPoint" information was not considered to
affect the Geotransform. This was corrected in 1.8 and is described in
this RFC:
http://trac.osgeo.org/gdal/wiki/rfc33_gtiff_pixelispoint
Note that this does not have a different result depending on the warper
resampling kernel used.
Best regards,
