19 The gdal_edit.py script can be used to edit in place various
20 information of an existing GDAL dataset (projection, geotransform,
21 nodata, metadata).
22 It works only with raster formats that support update access to
24 existing datasets.
25 CAUTION: depending on the format, older values of the updated
27 information might still be found in the file in a 'ghost' state, even
28 if no longer accessible through the GDAL API. This is for example the
29 case of the GTiff format (this is not a exhaustive list)
30 --help-general:
32 Gives a brief usage message for the generic GDAL commandline
33 options and exit.
34 -ro:
36 (GDAL >= 1.11) Open the dataset in read-only. Might be useful for
37 drivers refusing to use the dataset in update-mode. In which case,
38 updated information will go into PAM .aux.xml files.
39 -a_srs srs_def:
41 Defines the target coordinate system. This coordinate system will be
43 written to the dataset. If the empty string or None is specified, then
44 the existing coordinate system will be removed (for TIFF/GeoTIFF, might
45 not be well supported besides that).
46 -a_ullr ulx uly lrx lry:
48 Assign/override the georeferenced bounds of the dataset.
49 -tr xres yres :
51 Set target resolution. The values must be expressed in
52 georeferenced units. Both must be positive values.
53 -unsetgt:
55 Remove the georeference information.
56 -unsetrpc:
58 (GDAL >= 2.4) Remove RPC information.
59 -unsetstats:
61 (GDAL >= 2.0) Remove band statistics information.
62 -stats:
64 (GDAL >= 2.0) Calculate and store band statistics.
65 -setstatsmin max mean stddev:
67 (GDAL >= 2.4) Store user-defined values for band statistics
68 (minimum, maximum, mean and standard deviation). If any of the
69 values is set to None, the real statistics are calclulated from the
70 file and the ones set to None are used from the real statistics.
71 -approx_stats:
73 (GDAL >= 2.0) Calculate and store approximate band statistics.
74 -a_nodata value:
76 Assign a specified nodata value to output bands.
77 -unsetnodata:
79 (GDAL >= 2.1) Remove existing nodata values.
80 -scale value:
82 (GDAL >= 2.2) Assign a specified scale value to output bands. If a
83 single scale value is provided it will be set for all bands.
84 Alternatively one scale value per band can be provided, in which
85 case the the number of scale values must match the number of bands.
86 If no scale is needed, it it recommended to set the value to 1.
87 Scale and Offset are generally used together. For example, scale
88 and offset might be used to store elevations in a unsigned 16bit
89 integer file with a precision of 0.1, and starting from -100. True
90 values would be calculated as: true_value = (pixel_value * scale) +
91 offset Note: these values can be applied using -unscale during a
92 gdal_translate run.
93 -offset value:
95 (GDAL >= 2.2) Assign a specified offset value to output bands. If a
96 single offset value is provided it will be set for all bands.
97 Alternatively one offset value per band can be provided, in which
98 case the the number of offset values must match the number of
99 bands. If no offset is needed, it recommended to set the value to
100 0. For more see scale.
101 -colorinterp_X red|green|blue|alpha|gray|undefined:
103 (GDAL >= 2.3) Change the color interpretation of band X (where X is
104 a valid band number, starting at 1)
105 -gcp pixel line easting northing [elevation]:
107 Add the indicated ground control point to the dataset. This option
108 may be provided multiple times to provide a set of GCPs.
109 -unsetmd:
111 (GDAL >= 2.0) Remove existing metadata (in the default metadata
112 domain). Can be combined with -mo.
113 -mo 'META-TAG=VALUE':
115 Passes a metadata key and value to set on the output dataset if
116 possible. This metadata is added to the existing metadata items,
117 unless -unsetmd is also specified.
118 -oo 'NAME=VALUE':
120 (GDAL >= 2.0) Open option (format specific).
121 -a_ullr, -tr and -unsetgt options are exclusive.
123 -unsetstats and either -stats or -approx_stats options are exclusive.
