==========================
Gdalinfo
==========================
**What it does**        

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

It 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.

|

**How to use it**

Select from history a suported raster file and choose either Json or Text format for result display.

An additional option can list available subdatasets.

|

**Other options, advanced usage**


*-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*

    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 

|

*-proj4*

    Report a PROJ.4 string corresponding to the file's coordinate system.
