Roland, I believe gdal_grid takes an ogr file as input and creates a raster from a point layer. If you just want to resample a raster, try gdalwarp, without the warping:
kyle@local$ gdalwarp -ts 118 188 -r cubicspline coarse.tif fine.tif where -ts is 'target size' and -r is resampling method. See gdalwarp documentation for info: http://gdal.org/gdalwarp.html also here is the gdal_grid info: http://gdal.org/gdal_grid.html /** * * Kyle Shannon * ksshan...@gmail.com * */ On Wed, Dec 21, 2011 at 04:13, RolandB <rba...@gmail.com> wrote: > Dear users, > > I want use gdal for some file transformation. > Any help in solving the issue is greatly appreciated by me!
