I am using QGis 1.8 and I want to build overviews (pyramids) for satellite imagery using the Gdal Tool. I would like to use the resampling method “cubic convolution”, but the option doesn’t exist although it is listed in the online help (http://www.gdal.org/gdaladdo.html). Two other options are in my list that don’t show up in the online help however: “nearest” and “mode”.
Does anybody know why “cubic” isn’t there or can recommend me one of the other methods for use with satellite imagery?
Thanks a lot in advance,
Elena
