The gdal_translate utility can be used to convert raster data between different formats, potentially performing some operations like subsettings, resampling, and rescaling pixels in the process.

-ot: type
For the output bands to be of the indicated data type.
Do'nt be forgiving of mismatches and lost data when translating to the output format.
-of format:
Select the output format. The default is GeoTIFF (GTiff). Use the short format name.
-b band:
Select an input band band for output. Bands are numbered from 1 Multiple -b switches may be used to select a set of input bands to write to the output file, or to reorder bands.
-expand rgb|rgba:
(From GDAL 1.6.0) To expose a dataset with 1 band with a color table as a dataset with 3 (RGB) or 4 (RGBA) bands. Usefull for output drivers such as JPEG, JPEG2000, MrSID, ECW that don't support color indexed datasets.
-outsize xsize[%] ysize[%]:
Set the size of the output file. Outsize is in pixels and lines unless '' is attached in which case it is as a fraction of the input image size.
-scale [src_min src_max [dst_min dst_max]]:
Rescale the input pixels values from the range src_min to src_max to the range dst_min to dst_max. If omitted the output range is 0 to 255. If omitted the input range is automatically computed from the source data.
-srcwin xoff yoff xsize ysize:
Selects a subwindow from the source image for copying based on pixel/line location.
-projwin ulx uly lrx lry:
Selects a subwindow from the source image for copying (like -srcwin) but with the corners given in georeferenced coordinates.
-a_srs srs_def:
Override the projection for the output file. The srs_def may be any of the usual GDAL/OGR forms, complete WKT, PROJ.4, EPSG:n or a file containing the WKT.
-a_ullr ulx uly lrx lry:
Assign/override the georeferenced bounds of the output file. This assigns georeferenced bounds to the output file, ignoring what would have been derived from the source file.
-a_nodata value:
Assign a specified nodata value to output bands.
Passes a metadata key and value to set on the output dataset if possible.
Passes a creation option to the output format driver. Multiple -co options may be listed. See format specific documentation for legal creation options for each format.
-gcp pixel line easting northing:
Add the indicated ground control point to the output dataset. This option may be provided multiple times to provide a set of GCPs.
Suppress progress monitor and other non-error output.
Copy all subdatasets of this file to individual output files. Use with formats like HDF or OGDI that have subdatasets.
The source dataset name. It can be either file name, URL of data source or subdataset name for multi-dataset files.
The destination file name.
