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.

       -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.
