# gdalinfo

Lists information about a raster dataset.

## Description

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

The following command line parameters can appear in any order

`-json```

  Display the output in json format.

`-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 want 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.

`-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`

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

  `WKT1`

  `WKT2` (latest WKT version, currently WKT2_2018)

  `WKT2_2015`

  `WKT2_2018`

  New 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.

  New 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()`.

New in version 2.1.
