==========================
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.
