NAME
       gdalinfo - gdalinfo lists information about a raster dataset

SYNOPSIS
       gdalinfo [--help-general] [-mm] [-stats] [-nogcp] [-nomd]
                [-noct] [-checksum] [-mdd domain]* datasetname

DESCRIPTION
       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.

       -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 the ones.

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

       -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

       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.
