# 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.
