DESCRIPTION

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.

-not_strict:

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.

-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.

-mo "META-TAG=VALUE":

Passes a metadata key and value to set on the output dataset if possible.

-co "NAME=VALUE":

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.

-quiet:

Suppress progress monitor and other non-error output.

-sds:

Copy all subdatasets of this file to individual output files. Use with formats like HDF or OGDI that have subdatasets.

src_dataset:

The source dataset name. It can be either file name, URL of data source or subdataset name for multi-dataset files.

dst_dataset:

The destination file name.

EXAMPLE

gdal_translate -of GTiff -co "TILED=YES" utm.tif utm_tiled.tif
