[gdal-dev] Raster Scaling

[m k]

Im not sure if you are looking to rescale a whole map, or just individual rasters. If just rasters, I believe what you are looking for is: 
gdal_translate -outsize xsize[%] ysize[%] [file source] [file output]

Subject: [gdal-dev] Raster Scaling

Hi list,
I've recently found an interest in scaling rasters. Mainly because of poor georeferencing techniques that the users applyed a few years ago.
I've written a python script using gdal to alter the transformation parameters thus scaling the map.

Is there any tool in gdaltools that does this kind of task? If now, Is there any interest in using this (really simple) code?
