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

-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.

-nrat

Suppress printing of raster attribute table.

-noct

Suppress printing of color table.

-checksum

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

-mdd domain

Report metadata for the specified domain

-nofl

(GDAL >= 1.9.0) Only display the first file of the file list.

-sd subdataset

(GDAL >= 1.9.0) If the input dataset contains several subdatasets read and display a subdataset with specified number (starting from 1). This is an alternative of giving the full subdataset name.

-proj4

(GDAL >= 1.9.0) Report a PROJ.4 string corresponding to the file's coordinate system.

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.
