NAME


gdalinfo - gdalinfo lists information about a raster dataset

SYNOPSIS


gdalinfo [--help-general] [-mm] [-stats] [-hist] [-nogcp] [-nomd]
[-norat] [-noct] [-nofl] [-checksum] [-proj4]
[-listmdd] [-mdd domain|`all`]*
[-sd subdataset] 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.

-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.

-listmdd
(GDAL >= 1.11) List all metadata domains available for the dataset.

-mdd domain
Report metadata for the specified domain. Starting with GDAL 1.11, 'all' can be used
to report metadata in all domains

-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.
