NAME

gdalinfo - lists information about a raster dataset

SYNOPSIS

 
 gdalinfo [--help-general] [-mm] [-stats] [-nogcp] [-nomd]
          [-noct] [-checksum] [-mdd domain]* 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.
-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 the ones.
-nomd
Suppress metadata printing. Some datasets may contain a lot of metadata strings.
-noct
Suppress printing of color table.
-checksum
Force computation of the checksum for each band in the dataset.
-mdd domain
Report metadata for the specified domain

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.
