# gdal_translate

converts raster data between different formats

Usage:

    gdal_translate [--help-general]
           [-ot {Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/
                 CInt16/CInt32/CFloat32/CFloat64}] [-not_strict]
           [-of format] [-b band] [-outsize xsize[%] ysize[%]]
           [-scale [src_min src_max [dst_min dst_max]]]
           [-srcwin xoff yoff xsize ysize] [-projwin ulx uly lrx lry]
           [-a_srs srs_def] [-a_ullr ulx uly lrx lry] [-a_nodata value]
           [-gcp pixel line easting northing]*
           [-mo "META-TAG=VALUE"]* [-quiet] [-sds]
           [-co "NAME=VALUE"]*
           src_dataset dst_dataset

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 file name.
dst_dataset:
  The destination file name.

Example:

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