You could override the values in a VRT produced by gdal_translate -of VRT source_dataset out.vrt But it is dubious that changing the original values reported by the driver is going to produce something correct. > > I want to make sure that there are not any pixel shifts during > re-projection. > If gdalwarp.exe is not a good option for it, what are other methods for it? > I want to reproject a MODIS file. There have been recent discussions about why GDAL warping is not appropriate for datasets that have bow-tie : http://osgeo-org.1560.x6.nabble.com/gdal-dev- gdalwarp-problems-with-MODIS-L1B-td5206583.html There are a few hints in http://stackoverflow.com/questions/27968890/reproject- and-mosaic-modis-level2-using-gdal-python At that time, I see you were looking for a fast(er) gdal_grid. Recently I've added in trunk (post 2.0) a linear interpolation method which runs several magnitude of order faster than the other methods.
