SYNOPSIS


gdalinfo [--help-general] [-json] [-mm] [-stats] [-hist] [-nogcp] [-nomd]
[-norat] [-noct] [-nofl] [-checksum] [-proj4]
[-listmdd] [-mdd domain|`all`]*
[-sd subdataset] [-oo NAME=VALUE]* datasetname

DESCRIPTION

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

-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
(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.
-oo NAME=VALUE:
(starting with GDAL 2.0) Dataset open option (format specific)

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

Starting with GDAL 2.1, this utility is also callable from C with GDALInfo().
