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: 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.
- -mo 'KEY=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.
- -mo 'META-TAG=VALUE':
- Add the indicated metadata values to the output dataset.
- -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:
- Supress progress monitor and other non-error output.
- -sds:
- Copy all subdatsets 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
