## Description

gdalinfo program lists various information about a GDAL supported raster dataset.

The following command line parameters can appear in any order

--help

  Show this help message and exit

--help-general

  Gives a brief usage message for the generic GDAL commandline options and exit.

-json

  Display the output in json format. Since GDAL 3.6, this includes key-value pairs useful for building a STAC item , including statistics and histograms if `-stats` or `-hist` flags are passed, respectively.

-mm

  Force computation of the actual min/max values for each band in the dataset.

-stats

  Read and display image statistics. Force computation if no statistics are stored in an image.

-approx_stats

  Read and display image statistics. Force computation if no statistics are stored in an image. However, they may be computed based on overviews or a subset of all tiles. Useful if you are in a hurry and don't need precise stats.

-hist

  Report histogram information for all bands.

-nogcp

  Suppress ground control points list printing. It may be useful for datasets with huge amount of GCPs, such as L1B AVHRR or HDF4 MODIS which contain thousands of them.

-nomd

  Suppress metadata printing. Some datasets may contain a lot of metadata strings.

-norat

  Suppress printing of raster attribute table.

-noct

  Suppress printing of color table.

-nonodata

  Added in version 3.10.

  Suppress nodata printing. Implies `-nomask`.

  Can be useful for example when querying a remove GRIB2 dataset that has an index .idx side-car file, together with `-nomd`

-nomask

  Added in version 3.10.

  Suppress band mask printing. Is implied if `-nonodata` is specified.

-checksum

  Force computation of the checksum for each band in the dataset.

-listmdd

  List all metadata domains available for the dataset.

-mdd <domain>|all

  adds metadata using:

  `domain` Report metadata for the specified domain.

  `all` Report metadata for all domains.

-nofl

  Only display the first file of the file list.

-wkt_format WKT1|WKT2|WKT2_2015|WKT2_2018|WKT2_2019

  WKT format used to display the SRS. Currently the supported values are:

  `WKT1`

  `WKT2` (latest WKT version, currently WKT2_2019)

  `WKT2_2015`

  `WKT2_2018` (deprecated)

  `WKT2_2019`

  Added in version 3.0.0.

-sd <n>

  If the input dataset contains several subdatasets read and display a subdataset with specified `n` number (starting from 1). This is an alternative of giving the full subdataset name.

-proj4

  Report a PROJ.4 string corresponding to the file's coordinate system.

-oo <NAME>=<VALUE>

  Dataset open option (format specific).

-if <format>

  Format/driver name to be attempted to open the input file(s). It is generally not necessary to specify it, but it can be used to skip automatic driver detection, when it fails to select the appropriate driver. This option can be repeated several times to specify several candidate drivers. Note that it does not force those drivers to open the dataset. In particular, some drivers have requirements on file extensions.

  Added in version 3.2.

The gdalinfo will report all of the following (if known):

- The format driver used to access the file.

- Raster size (in pixels and lines).

- The coordinate system for the file (in OGC WKT).

- The geotransform associated with the file (rotational coefficients are currently not reported).

- Corner coordinates in georeferenced, and if possible lat/long based on the full geotransform (but not GCPs).

- Ground control points.

- File wide (including subdatasets) metadata.

- Band data types.

- Band color interpretations.

- Band block size.

- Band descriptions.

- Band min/max values (internally known and possibly computed).

- Band checksum (if computation asked).

- Band NODATA value.

- Band overview resolutions available.

- Band unit type (i.e.. "meters" or "feet" for elevation bands).

- Band pseudo-color tables.

## C API

This utility is also callable from C with `GDALInfo()`.

Added in version 2.1.
